Ep 172 Childhood Vaccine Schedule 1: Let’s give it a shot

00:00:00
Speaker 1: A calamity of the most serious kind has swept down upon this beautiful group of islands, and its ravages will have to be computed not by the hundred, but by thousands. A most extraordinary scene was presented of whole towns, with the houses closed, the lanes and squares silent as death, and the inhabitants all down, old men and infants, young men and mothers of families, one heap of illness. The destroying angel had silenced every dwelling, and there was a weird quiet about the place that struck very peculiarly upon one's feelings. Daily the canoes were to be seen carrying the dead to their breezy resting places on the opposite shore, and day and night was the death drum beating, and the wails of the mourners rose on the air. Strong winds and heavy rains added to the horrors of the situation, and the bowens almost starved for food, the people being unable to get to the mainland, where their gardens were hard worked in the day and with broken rest at night. I passed through some weeks the like of which I hope never to see again at home in our own land. There is always a large proportion of healthy persons who act as a relief to the many stricken by prevailing disease. But here you have a whole country down, all sick men, women and children dying all around you every day, your best friends among the people dying.

00:02:16
Speaker 2: It's so horrific erin, it's awful.

00:02:20
Speaker 3: It is.

00:02:22
Speaker 1: Almost unfathomable. And yet that is a first hand account. That is what really happened. That is a diary entry from the Reverend AJ Webb, who was a missionary in Fiji at the time of the eighteen seventy five outbreak that killed a quarter of the population of measles from sorry, yes, of measles, measles, measles, measles.

00:02:49
Speaker 2: Yeah, it is really terrifying.

00:02:51
Speaker 3: And yeah, so it makes me so thankful that we have a vaccine, Like I truly cannot imagine living in a time when this was reality.

00:03:00
Speaker 1: Should not be forgotten, like it can't be. Hi, I'm Aaron.

00:03:05
Speaker 2: Welsh, and I'm Aaron Allman.

00:03:06
Speaker 1: Updike, and this is this podcast will kill you.

00:03:09
Speaker 2: And we're coming at you with season eight. Season eight.

00:03:14
Speaker 1: Yeah, Season seven was like literally yesterday, And so if you did notice a long break between seasons that is by design, that is intentional.

00:03:26
Speaker 2: There wasn't a break. There wasn't you know.

00:03:28
Speaker 1: Given all of the disturbing and widespread changes that are happening to public health and the sciences here in the US, we decided, you know, maybe we should just like keep things rolling, trying to stay on top of some of these horrific changes and provide you all with clear info and reliable sources for some of the things that you're seeing splashed across headlines, things like devastating funding cuts to scientific research, outbreaks of vaccine preventable illnesses, including measles, the intentional concealment of vital public health information, massive cuts to healthcare access, a profiteer of vaccine disinformation at the helm of the most significant public health institution in the US. The list goes on. Yeah, yep, misinformation is everywhere, and it's growing by the second.

00:04:20
Speaker 2: It really is.

00:04:21
Speaker 3: And the truth is, we are all all of us susceptible to it, every one of us, even me and you, even if we think we aren't or we like to think we aren't. So what do we do about it?

00:04:37
Speaker 2: What do we do about it? Well, we'll tell you what we're going to do about it.

00:04:42
Speaker 3: What we are going to do is, through this podcast throughout the season, continue to be sources of reliable information about issues in health and medicine, to continue to provide historical context about scientific developments, and to explore the current research shaping the future of health on planet. That is what we have done, that is what we will continue to do. Our list for this season is long and so far includes fun things like raw milk, SSRIs avian influenza, we hear you, We're doing it, and fluoride and literally so many more.

00:05:18
Speaker 2: It's a long list.

00:05:19
Speaker 1: Do you notice a trend? Yeah.

00:05:22
Speaker 3: So, to help us fill out the schedule for this season and prioritize our focus, we wanted to ask you, guys all for your help. What do you want to learn about? What topics are you seeing misinformation about? Which episodes that we've done in the past. Would you like an update on? Yes, let us know reach out. The best way to do that is through the contact us form on our website this podcast will kill You dot com, or you can send us an email to this podcast will Kill You at gmail dot com.

00:05:48
Speaker 1: Yep, Yes, we can't wait to hear from you. Yeah, it's going to be a it's going to be a season full of info.

00:05:57
Speaker 2: It's going to be a season period moving on on. What are we doing now? What are we doing now?

00:06:03
Speaker 1: Yes, this week and next week we are going to be talking about the childhood vaccine schedule, especially the one that we have here in the US. And this actually it's funny because like we ended the pregnancy series and we were like, oh, well, and we'll talk about childhood stuff some other times. We'll talk about infancy some other time, and actually this is like kind of a follow up.

00:06:24
Speaker 2: It's a nice it's almost like we planned it. It is.

00:06:28
Speaker 1: And part of the reason that we decided to do this is because, you know, you may have come across the news that RFK Junior, who is longtime anti vaccine activist and now the Secretary of the US Department of Health and Human Services, has indicated that he intends to investigate the childhood vaccine schedule, after saying previously that he would not. What are the possible consequences of this investigation. That's what we're going to explore.

00:06:56
Speaker 2: That's what we want to know.

00:06:57
Speaker 1: Yes, And so to do this, we're splitting this topic into two episodes because we want to first just do a general review of how vaccines work, what these childhood vaccines protect us against, and what these vaccinations do for us as individuals and as members of a community. And then in our second episode, we're going to go deeper into.

00:07:19
Speaker 2: The schedule itself.

00:07:20
Speaker 1: You know, what vaccines do kids get and when, how we decided upon this vaccination schedule, how and why it differs from schedules and other parts of the world. Some of the latest trends and outbreaks of vaccine preventable diseases. And finally, just some strategies on how to talk with people who might be on the fence about vaccines.

00:07:39
Speaker 2: Just a few small topics for us to cover in two episodes. We no problem fast.

00:07:45
Speaker 3: Before we get into all of that, it is quarantine any time is aaron.

00:07:51
Speaker 1: This week we're drinking Boosted Boosted. What's in boosted because I have already forgotten?

00:08:00
Speaker 3: So it's a delicious little bev gin lemonade and raspberries raspberry.

00:08:07
Speaker 2: Lemonade at gin.

00:08:08
Speaker 1: If you prefer easypasy, delicious, crazy squeezy.

00:08:15
Speaker 3: We'll post the full recipes on our website This podcast will Kill You dot com, as well as our social media channels.

00:08:21
Speaker 2: If you're not following us, you should be.

00:08:23

00:08:43
Speaker 3: Wealth of information, goodness, say business, welcome back, good to see.

00:08:51
Speaker 2: You, welcome back.

00:08:52
Speaker 3: It's been so long, All right, let's start right after a short break.

00:09:13
Speaker 1: Childhood vaccine schedules have been, for quite some time a major target of anti vaccine propaganda. Vaccine disinformation spreaders want people to question, why do we need so many? Don't these vaccines overwhelm our immune systems?

00:09:29
Speaker 2: Do they aerin? No?

00:09:34
Speaker 1: Long story short, you're right. Rather than declaring vaccines unsafe just across the board, these anti vaccine activists seek to reach a broader audience by normalizing vaccine hesitancy and making it more palatable. You know. They reframe their position from anti vax, which is more alienating it's extreme, to pro safe vaccination, because who doesn't want safe vaccines, right, we all want safe vaccines.

00:10:02
Speaker 2: We have vaccines. Safe vaccines is the thing. I want that, and we have that, and we have them.

00:10:08
Speaker 1: And the truth is that the vaccines we have, the schedule we use, these things are safe and they have been proven to be so over the decades, with so much data to back this up. And we'll get more into that in these episodes. Parents want the best for their children. They want to set them up for a happy and healthy life. Every decision that you make seems fraught with the potential for harm. Things like which crib to choose, what sleeping schedule is going to be the best.

00:10:40
Speaker 2: Belong to you even I don't know, I have no.

00:10:46
Speaker 1: Idea, But you want to do the right thing for your child. Wanting to make the right decision and worrying about the outcome is completely understandable. To help you decide what to do, you may ask your doctor, You may talk with your trusted friends, or you may you know, ask the internet.

00:11:05
Speaker 2: Consult the tickto consult TikTok. Oh, gosh, no, don't consult TikTok.

00:11:12
Speaker 1: But each of these things might advise you differently, or they might see the balance of risks and benefits differently. When it comes to vaccines, finding reliable information on the internet is increasingly challenging, and given our medical system here in the US, finding the time to make an appointment with your doctor to fact check some of the things that you've read about vaccines on the internet that can be next to impossible.

00:11:35
Speaker 2: Yeah right. Or let's say that you.

00:11:38
Speaker 1: Do find the time and you find the money to make an appointment to talk with your doctor, and somehow, in that ten minute appointment, you managed to squeeze in a couple of questions about vaccines, and your doctor just scoffs and condescends to you, making you feel bad for asking these questions in the first place. And maybe you can't shake that little seed of doubt planted by a TikTok video that you saw that was spouting vaccine misinformation, This video that makes you ask what if? The what if that anti vaccine activists the question that they try to plant is what if these vaccines are not safe? When really the what if should be what if my child gets measles? Yeah, disinformation spreaders minimize that future threat of being unvaccinated, and they falsely amplify the minuscule risks posed by vaccinations, or they just invent risks altogether. Choosing not to vaccinate gives you the illusion of control, when in fact, it takes it away entirely because you cannot predict whether your child will be the one to die in a measles outbreak, or one of the ones to die in a measles outbreak, or it is it's so tremendously sad. You can't predict whether they'll have permanent lung damage after about of whooping cough, which they also transmitted to a baby that was too young to be vaccinated. We want to start these episodes with the message that we get it right. It is easy to fall prey to this vaccine disinformation because of the way that it plays on those specific fears, because it gives you this illusion of control, because it tells you that you're doing right by your child. Vaccine disinformation is specifically engineered to do this.

00:13:27
Speaker 2: Right, and not just on TikTok. I feel like we no, no, I know we lasted poor TikTok a few times.

00:13:32
Speaker 1: Yes we have, yeah, but it's everywhere in everything.

00:13:36
Speaker 2: Yeah.

00:13:37
Speaker 1: And addressing each one of the invalid claims that are made by anti vaccine activists, it can actually breathe more air into their movement. And so rather than doing targeted mythbusting, what we're going to do in this and next episode is we're going to present the factual information about vaccines, the diseases that they prevent, and why we have childhood vaccine schedule that we do.

00:14:02
Speaker 2: Yeah.

00:14:02
Speaker 1: So first, Aaron, let's start back at the beginning.

00:14:05
Speaker 2: What are vaccines and.

00:14:07
Speaker 1: How do they work?

00:14:08
Speaker 3: I can't wait to get into this, Aaron. It's really just like an appreciation of our immune system for a moment here.

00:14:15
Speaker 1: Ready, love our immune system.

00:14:18
Speaker 3: Every single time that we breathe in, everything that we put in our mouths, that we wipe across our snotty noses that we rub into our eyes, all of this exposes us to antigens. And antigen is just the fancy medical word for stuff that our immune system can recognize as not me right, not self. We are exposed to these antigens all the time, from literally the minute that we're born and we take our first breath and we open our eyes, and once these antigens enter our body, they get recognized by white blood cells, whose job is antigen recognition.

00:14:58
Speaker 2: That's their title.

00:15:00
Speaker 3: Then they present that antigen to other white blood cells in our lymph nodes. Some of these white blood cells in our lymph nodes make antibodies, and antibodies are like little Lego flags that are hyper specific markers that can recognize and lego click onto one single antigen or like one part of one single antigen.

00:15:25
Speaker 1: I love, I love the visual of a lego flag.

00:15:27
Speaker 2: It's just, you know, and they they really do. He and key in lock can't lock.

00:15:34
Speaker 3: Lego and they they basically flag it for destruction. That's what an antibody is doing. But the part that actually protects us in the long term is that these antibody producing cells stick around in our bodies so that if that particular antigen ever dares to show its face in our body again, we're ready for it, right. These memory cells can suit quickly make a whole bunch more of these Lego flags and just stick them all over any anigens that dare to enter before that virus or bacteria or whatever it is can make us sick. And this process is how our antibody mediated immune response, which is just one of our incredible immune system things.

00:16:21
Speaker 2: That's how it works across the board.

00:16:23
Speaker 3: When we are sick with a viral infection or a bacterial infection like the flu or something else, our immune system is running through this whole immune response, but it's doing so while the virus is replicating, and then we get super super sick.

00:16:39
Speaker 2: Yeah, and we can die exactly.

00:16:43
Speaker 3: We're protected from a repeat infection. But there is a cost, right, some of us will get very sick, we might be hospitalized, we might even die from this infection. So what vaccines do is just allow us to produce these antibodies that will protect us from a future your infection without ever having to get sick in the first place.

00:17:05
Speaker 1: That's what they do.

00:17:06
Speaker 2: Like, it's just truly incredible. It is.

00:17:09
Speaker 1: It is.

00:17:10
Speaker 2: Vaccines are so I love them.

00:17:14
Speaker 1: I'm like, it's simply put.

00:17:18
Speaker 2: It's simply put.

00:17:19
Speaker 3: Because vaccines are just introducing these antigens in a very small amount in a in a specific time and place.

00:17:29
Speaker 1: It's a shortcut that saves lives and saves saves permanent injury and illness and even just short term right, right, like being miserable with the flu.

00:17:42
Speaker 2: You don't have to feel that, right.

00:17:44
Speaker 3: It's They're incredible, And there are a number of different types of vaccines that we use. There are things like live attenuated vaccines. There are killed virus or killed bacteria vaccines, There are toxoid vaccines, there are mRNA vaccines, and there are lots of other types of like specific.

00:18:02
Speaker 1: Vaccines, subtypes and whatnot.

00:18:04
Speaker 3: Yeah, we can link to so many detail more detail, but the bottom line is that each of these different types of vaccines has both pros and cons and some types of vaccines are going to work better for some diseases than others. And when people, meaning regulatory bodies, are deciding which vaccine is approved or included in our vaccine schedule, they're looking at things like efficacy, safety, and how well it produces an immune response. All of these things have to be considered. And every single vaccine, just like every single thing that we put into our bodies, medicine, food, quarantinies, all of it, as well as every single disease or pathogen that we're exposed to, has a potential for side effects. But the side effects of vaccines are generally quite mild.

00:18:55
Speaker 2: There are things like.

00:18:56
Speaker 3: A sore arm, swelling maybe around the injection site. Fever now fevers in children can sometimes cause seizures and while vaccines can cause a fever, febrile seizures after vaccination are actually quite rare, and you're far more likely to get a febrile seizure from an infection rather than a vaccination, right, And in general, any serious side effects from a vaccine, like, for example, the rash that can happen after an MMR or a veraricella vaccine, they tend to be milder versions of the same symptoms that you can have from the disease itself, But most of the time you can't then spread that to others the way that you can in the context of an infectious disease, right.

00:19:43
Speaker 1: Right.

00:19:44
Speaker 3: The only risk that exists with vaccination that doesn't really exist with what people call natural infections whatever that means, is the potential for an allergic reaction, and that mostly has to do with vaccine component rather than the antigens from that virus or bacteria itself. And it's estimated that there are one to two severe allergic reactions per million doses of vaccines. So when we're comparing risks and benefits, we have to compare apples to apples. One to two severe allergic reactions per million doses of vaccine. If we're looking at measles, for example, one in five kids with measles is hospitalized with severe infection, and one to three of every one thousand kids with measles will.

00:20:35
Speaker 1: Die, one to three for every one thousand kids.

00:20:40
Speaker 3: Yeah, and no kid should be dying from a disease that we can prevent.

00:20:44
Speaker 1: No, no, no.

00:20:47
Speaker 3: So that's like how vaccines work across the board, and a little bit of the risks and comparing the actual risks to risks of the diseases that we're preventing against. So, if we're talking about the childhood vaccinations schedule, what are the vaccines on that schedule and what are the diseases that we're actually able to prevent.

00:21:10
Speaker 1: Yes, let's go through it.

00:21:12
Speaker 3: Let's we're going to back and forth. This this is a fun this is not episode.

00:21:18
Speaker 2: It's been fun to put together.

00:21:20
Speaker 3: Yeah, but before we get into it, let's take a quick break and then we'll come back with all of these vaccines and diseases.

00:21:28
Speaker 1: Yeah.

00:21:29
Speaker 3: Wait, So when we're talking about protecting kids, which is what we're talking about in this episode, we actually can start before they're even born because there are some vaccines that we can give during pregnancy to provide passive immunity to the baby, which includes t DApp and we'll get into the diseases covered by that vaccine in a little bit, but it also includes RSV, And if you didn't get the RSV vaccine during pregnancy, there's another type of immunization works a little bit differently that your baby can get in the first week of life. So Aaron walk us through what is RSV? What is the RSV vaccine protecting us from?

00:22:22
Speaker 1: Okay, I am going to tell you all of that, but first I've realized we should probably mention that we have disease specific episodes for many of the diseases that we will cover, in addition to a two parter on vaccines right the history of their development and how they work, more detail about all of this, And so just as a little preamble to this section, we will link to all of these other episodes in the show notes for this one and on our website. And so if you want more info.

00:22:52
Speaker 2: We've got so much.

00:22:54
Speaker 3: I feel like we said that to each other so many times while we were working on this episode.

00:22:57
Speaker 2: That we forgot to say it. We're like, oh, it will obviously We'll say that a million times.

00:23:03
Speaker 3: Yeah, okay, but anyway, want more detail, We've got it.

00:23:07
Speaker 2: This is overview. Go.

00:23:09
Speaker 1: RSV is one of those we do have an RSV episode.

00:23:12
Speaker 2: Okay, Yeah.

00:23:13
Speaker 1: RSV stands for respiratory sensitial virus, and, as its name suggests, it is a respiratory infection.

00:23:20
Speaker 2: It sure is.

00:23:21
Speaker 1: It's transmitted via air and direct contact, and for most adults, infection with RSB is relatively mild, but in infants and in elderly adults or those who have lung issues, it can be deadly or it can lead to complications like repeat hospitalizations, long term lung impairment, and asthma, or recurrent weez There is no widely available treatment for RSV widely available, and each year this virus causes three point six million hospitalizations globally and an estimated one hundred thousand deaths in children under the age of five, one hundred thousand.

00:24:00
Speaker 2: Which is so s I know, I know it's going to be on repeat.

00:24:04
Speaker 1: Yeah, We're going to be repeating so many numbers. I feel like both the vaccine given to the pregnant person and the monoclonal antibody given to a newborn offer short term protection for the newborn until their lungs are a bit more developed, and then they're less likely at that point to have a severe infection that requires hospitalization.

00:24:22
Speaker 3: Yeah, and in general, people are recommended to get one or the other YEP. So if they didn't get the RSV vaccine during pregnancy, then that baby will get the monoclonal antibody imanization. But most babies, the first vaccine that they will get is actually hepatitis B, which is given right after birth, usually within the first twenty four to forty eight hours of life.

00:24:43
Speaker 2: Aarin. What's hepatitis B.

00:24:46
Speaker 1: Well, the hepatitis BE virus. It's a viral infection. It's transmitted via blood and bodily fluids, and it can be transmitted from mother to baby at birth. And the real risk with hepatitis B, especially for those who are infected at a young age, is chronic infection, which can lead to liver cirrhosis and liver cancer. So, just to like emphasize this, here's some numbers. So it's estimated that five percent of adults newly infected with the hep B virus will develop chronic hepatitis, but ninety five percent of children under five who have the virus will develop it, which is why vaccination is so critical. The three dose series of this vaccine is nearly one hundred percent effective in entirely preventing infection with this virus.

00:25:36
Speaker 2: Nearly one hundred percent. It's amazing.

00:25:39
Speaker 1: And even though we've had a hepatitis B vaccine since the early nineteen eighties and estimated two hundred and fifty four million people around the world are chronically infected with this virus, with around one point two million new infections every year and an estimated one point one million deaths in twenty twenty two.

00:25:59
Speaker 2: Yeah, that's why we vaccinate.

00:26:02
Speaker 1: That is why we vaccinate.

00:26:04
Speaker 3: After the birth dose of hepatitis B, the first round of shots, as it's often called for babies in the US, is at two months old. So at the two month well child visit, we get five different vaccines plus a second dose of the hepatitis B. So we get DETAP, which is diphtheria tetanus and acellular protessis. We get IPv which is the inactivated poliovirus, and we get hib or hemophalous influenza type B and PCV or the new macaccle vaccine. As well as rotavirus.

00:26:43
Speaker 1: So Aaron and the second dose oft beat in a second.

00:26:46
Speaker 3: I said that I did so Aerin. That's a lot all at once. Can you please walk me through what each one of these diseases are?

00:26:56
Speaker 1: These five, these five vaccines. It's amazing. Okay, you are protected from.

00:27:00
Speaker 2: So many things.

00:27:02
Speaker 1: I know. Let's start with rotavirus, right.

00:27:04
Speaker 3: So.

00:27:04
Speaker 1: Rotavirus is transmitted fecal, oral, or direct contact with an infected individual or through contaminated objects. Symptoms of rotavirus can include watery diarrhea, vomiting, and severe dehydration that can lead to death if rehydration therapy is not provided. Rotavirus is a major killer globally, with a two point five percent case fatality rate in children who are living in low income countries. And even though we've had a vaccine since two thousand and eight, rotavirus still causes a substantial burden of global death and disease. So, for instance, in twenty sixteen, rotavirus was estimated to cause two hundred and fifty eight million infections globally and one hundred and twenty nine thousand deaths in children under the age of five.

00:27:53
Speaker 2: It's just so sad. Eric and so hard vaccine preventable diarrheal disease. Okay, okay, next more diphtheria.

00:28:04
Speaker 1: So, diphtheria is our first bacterial disease on this list, and it's our first in a combo shot along with the vaccines for tetanus and protessis detap is what the vaccine is called, detap.

00:28:16
Speaker 2: Yeah, T tap for adults. Hey, yes, if anyone's confused about that.

00:28:20
Speaker 1: In my head, I've been saying T tap detap, Which one is? Detap?

00:28:24
Speaker 2: It's fine detap.

00:28:26
Speaker 1: Diphtheria is caused by a bacterium named Karinibacterium diphtheria. Karanibacterium is just a really fun word to say, isn't it.

00:28:34
Speaker 2: It is.

00:28:35
Speaker 1: It's another respiratory pathogen. It's transmitted through sneezes and coughs, and the symptoms of diphtheria can be things like sore throat, fever, swollen necklands, weakness. And I still vividly remember from our diphtheria episode years ago, like back in twenty eighteen, twenty seventeen.

00:28:53
Speaker 2: It's very old, twenty I don't remember anyway, I mean it was months apart. It's yeah, it's stuck in your mind, suck in my mind.

00:29:02
Speaker 1: And this is one of the hallmark symptoms of diphtheria. It is a gray, odoriferous membrane made up of dead tissue that coats your respiratory tract and this makes it super difficult to swallow and breathe, like makes it difficult to breathe. The bacterium also produces a toxin that can injure your heart and your nerves, leading to long term complications. Diphtheria is an incredibly deadly infection, with death occurring in thirty percent of unvaccinated individuals without access to treatment like antibiotics or serum. But even having those things is not a guarantee of safety, right. A study that looked at diptheria cases in unvaccinated individuals between nineteen fifty nine and nineteen seventy found that even when treated with antibiotics, antiitoxin, and supportive care, ten percent of people died.

00:29:57
Speaker 2: Yeah, yeah, dip theoria is a scary one. It really is.

00:30:01
Speaker 1: Okay, we've got a few more for this round, a lot more.

00:30:05
Speaker 3: The well child check is a big deal. It's like when it's no longer truly terrifying. If your child gets a fever because before this point, like they're in the emergency room, you're concerned for a very serious infection if they have a fever. And after this they're protected from so many of the things that used to kill babies all the time.

00:30:27
Speaker 1: All the time.

00:30:28
Speaker 2: So like tetanus my tetanus next on our list.

00:30:31
Speaker 1: This is another bacterial disease caused by Claustridium tetani and most people probably know that it's transmitted through exposure to spores of this bacterium, which can live in soil, ash, rusty tools, and in the intestinal tracts and feces of humans and mammals who are infected with this infection can occur when you have like a deep puncture wound, but most tetanus infections actually happen during birth, like if the umbilical cord was cut with a contaminated tool or if the pregnant person not been adequately vaccinated. The symptoms of tetanus include painful muscle spasms, trouble swallowing. Lock job is another name for tetanus, seizures, headache, fever, blood pressure changes, elevated heart rate, and death is quite a common outcome. Even with all that modern medicine can offer. Like you, you know, get tetanus symptoms, show you go to the hospital right away. You have all of the best treatment in the world. And twenty twenty five, ten percent of people with tetanus will die from the infection, and those that do recover are not protected from future infections. Only the vaccine gives you immunity, not the infection itself, which.

00:31:42
Speaker 3: Is so interesting and like you could do a deep dive on why that is. And it's because we are exposed to a much larger amount of the toxin, but it can't actually make us sick, whereas that it's so interesting, yes.

00:31:52
Speaker 1: Yeah, yeah, so in and this is still a major problem around the world. The WJO reported that in twenty eighteen, twenty five thousand newborns died from neonatal tetanus. That is a huge number. Yeah, but that number, twenty five thousand was a ninety seven percent drop from nineteen eighty eight, when seven hundred and eighty seven thousand babies died within their first month of life from tetanus.

00:32:19
Speaker 2: Oh my god, erin in nineteen eighty eight, that's the year I was born.

00:32:23
Speaker 1: Yeah, there's more, there's more. These vaccines protect you FROMPHS protesis.

00:32:30
Speaker 2: So this is protestis is.

00:32:32
Speaker 1: The last in our tee dap trio detap. Sorry see I have written detap in my head wants to say tea dap okay protestas.

00:32:43
Speaker 2: So this protestis is.

00:32:44
Speaker 1: A bacterial disease caused by Bordetella protessis. This is another airborne infection. It's spread when someone talks, sneezes, or coughs, and symptoms can include fever, running nose, and the characteristic hacking cough of this infection that gives it its their name whooping cough. Protesses can turn into a very serious illness, especially in infants, and this disease remained a major killer in childhood for many parts of the world into the mid twentieth century, with the case fatality rate of around ten percent. Antibiotics aren't very effective against protessis, even though this is a bacterial infection, and antibiotics are mostly used just to reduce the spread of the disease, not reduce the severity of an individual infection Like that's what they're most effective against.

00:33:31
Speaker 3: Yeah, preventing other people in the community who are unvaccinated or under vaccinated from getting sick.

00:33:37
Speaker 2: Yes.

00:33:38
Speaker 1: A study from the CDC showed that kids not vaccinated against protessis or sixteen times more likely to get the infection compared to vaccinated kids. Within a few decades of the protest's vaccine being introduced, mortality rates dropped around ninety percent.

00:33:55
Speaker 2: Wow. Yes, yeah.

00:33:57
Speaker 1: And since babies can't get the protesters vavaccine right at birth, they are super vulnerable to this infection, which is why pregnant people get the vaccine during the last weeks of their pregnancy and why it's so important to be vaccinated, to be up to date on your vaccines if you're going to be spending time near a newborn.

00:34:15
Speaker 3: Yeah, yep, got to get those chots next next day.

00:34:21
Speaker 2: And there's so many more, so many two months well child check. I love I love doing this. By the way, this is filling, this is yeah.

00:34:28
Speaker 1: I just I just love that like this we have we're naming all these really scary things and there were also there are ways to prevent them from right.

00:34:38
Speaker 3: We're not just saying these are scary things. We're saying these are scary things that we protect against. When your child is two months old, yes, protected two months yep.

00:34:47
Speaker 1: Like Hemophilus influenzae type B, so this is also known as hibs bacteria that can cause severe respiratory infections, especially in children under five years of age. These bacteria are common residence of our respiratory tract and in most people they don't cause any disease. They're just part of our microbiome. But if a baby or a child gets exposed, HIB can cause severe invasive disease. So what does that mean. It means meningitis, it means pneumonia, it means severe ear infections, epiglottitis, even sepsis. Complications of infection such as deafness, blindness, cerebral palsy, and hydrocephalus happened at high rates. So there was a study that looked at the global burden of HIB infections prior to the vaccine and found that more than five hundred and twenty thousand children died of HIB infections every year.

00:35:42
Speaker 2: Wow, every year, that's a half a million babies. Yes globally ugh.

00:35:49
Speaker 1: Yes. Between twenty twenty fifteen, the vaccine has been estimated to save over one point two million children from dying of HIB, which is a decline of ninety percent and again, like with protessis, diphtheria and tetanus, this is not an infection where you can rely on antibiotics. Antibiotic resistance has become a real issue with hib and the search for and effective medication can cost you precious hours.

00:36:13
Speaker 3: Yeah, and especially with meningitis or with epiglottitis, which is very that's an infection of like your throat that basically makes it so that you can't breathe. It like blocks off your track yet so that you cannot breathe. So it's it's very severe if it's not treated right away. Yeah, So antibiotic resistance is super scary.

00:36:35
Speaker 2: Yep. But there's a vaccine.

00:36:36
Speaker 1: But there's a vaccine, just as there is a vaccine for pnumococcal conjugates. So this vaccine protects against a bacterium Streptoccus deemonia that's commonly found in people's respiratory tracts, kind of like hib who don't appear sick, and it's also transmitted it just lives there. And this one is also transmitted via the respiratory route, and infants and young children are especially susceptible to severe disease from this bacterium. And like hibs. Strep pneumonia can cause pneumonia, meningitis, sinus infections, ear infections, bacteremia, and sepsis.

00:37:08
Speaker 2: Yeah.

00:37:09
Speaker 1: The deployment of these vaccines between twenty and twenty fifteen reduced deaths globally due to strep pneumonia by fifty one percent.

00:37:18
Speaker 2: Yeah. Again, antibiotic resistance.

00:37:20
Speaker 1: Is a growing concern that makes these vaccines ever more important.

00:37:24
Speaker 3: This one also really hits home for me because the Newmaccco conjugate vaccine wasn't approved for kids until the year two thousand and In nineteen eighty eight, my older brother got meningitis from newmacaccle from Streptoccus pneumonia and almost died, did not die, lost his hearing completely. So it's like very much a reality that's not that long ago.

00:37:49
Speaker 2: It's like that was the year.

00:37:51
Speaker 3: That I was born. So these and I mean, we get pneumonia and things. These bacteria circulate everywhere all the time. So the fact that we have this vaccine is phenomenal.

00:38:02
Speaker 2: It is. Yeah, it is amazing, And we have more and we have more polio polio.

00:38:11
Speaker 1: Polio is caused by poliovirus, sure is it is. This virus is transmitted through the air like coughing or sneezing, and through the fecal oral root. Those who aren't symptomatic can still shed virus into the environment and infect others. Polio can cause fever, fatigue, headache, vomiting, stiff neck, and classically can sometimes progress to paralysis that is usually permanent. Paralysis can be so extreme that five to ten percent of people who have this symptom can die as a result.

00:38:45
Speaker 2: Yeah.

00:38:46
Speaker 1: There is no.

00:38:46
Speaker 2: Treatment, none, none for polio. None.

00:38:51
Speaker 1: There is only prevention via vaccination. In the US, In nineteen fifty two, which is the year before the vaccine was introduced, there were more than fifty seven thousand polio cases, twenty one thousand paralytic, and three thousand fatal in the US and the US alone. In twenty twenty three, zero cases in the US. Yeah, yep, and similar amazing improvements have been seen around the world. In nineteen eighty eight, when the global campaign to eliminate polio started, three hundred and fifty thousand people globally were paralyzed due to polio. Since then, cases have dropped ninety nine percent.

00:39:33
Speaker 2: It's amazing, it is amazing, so close and yet so far from eradication of polio.

00:39:39
Speaker 1: I know it's hard to because it's environmental contamination and all that stuff.

00:39:43
Speaker 2: Yeah, yeah, exactly.

00:39:45
Speaker 3: So most of all of those vaccines that we've had so far require multiple doses to provide enough protection. So as we're going through our childhood vaccine schedule, the next well child check is usually yet four months, and at that visit you actually get all those same ones that we just talked about, minus hepatitis B.

00:40:07
Speaker 2: You don't need a third dose of hepatitis B quite yet, okay.

00:40:11
Speaker 3: And then again at the sixth month visit, you'll get a third dose of that de TAP, another dose of that pneumonia, the newmococcal vaccine, another dose of the polio vaccine, and a third dose of the hepatitis B vaccine. And then, depending on like vaccine manufactures, because there's a few different types, there might be another dose of HIB, there might be another dose of the rotavirus, or sometimes you don't need those, depending on which ones you got, which one your doctor's off has had. But at six months old is also when babies are finally old enough to get their flu and covid shots. So Aaron, we all know about this one right, most people.

00:40:51
Speaker 1: Are familiar with both of these, I think, but we'll just go over them again.

00:40:56
Speaker 2: Yeah. COVID, right, I think we.

00:40:58
Speaker 1: All know, we all do?

00:41:00
Speaker 2: We know? Yeah, y'all know.

00:41:01
Speaker 1: We all know. COVID is caused by stars COVID two coronavirus, and at this point in time, it has caused over seven hundred and seventy seven million reported cases worldwide since twenty twenty probably.

00:41:13
Speaker 2: Five years, okay, nine even five years, and it.

00:41:16
Speaker 1: Has killed over seven million people since twenty twenty. And this of course continues to circulate and cause significant morbidity and mortality. Yep, yep, that's covid influenza. Of course, we know, you know, we know Influenza. It's also caused by a respiratory virus causes seasonal outbreaks, and in the US in the twenty twenty four to twenty twenty five season so far, as of the week of February twenty second, influenza has already resulted in ninety eight pediatric deaths and has caused at least thirty seven million illnesses, four hundred and eighty thousand hospitalizations, and twenty one thousand deaths overall from flu season so far. In the US alone, I actually can't.

00:42:04
Speaker 3: Like, those numbers are so astounding to me. It's been a very bad flu season, a very bad flu season, but like still, yeah, oh goodness, yep, So.

00:42:14
Speaker 2: That's fluent COVID.

00:42:15
Speaker 3: You're eligible for those at six months during flu season. Obviously it might you might be older if it's not flu season. Anyways, after six months in the US, on our schedule, there usually aren't any other vaccines at the nine month well baby visit, which is typically the next time that you'll see your doctor, unless you missed any of your vaccines. So then the next round of vaccines is at twelve months of age, and at this visit there'll be a few of our old faves. Now you'll get either your third or fourth dose, your final dose of HIB whether it was three or four, depends on the manufacturer, the fourth dose of the newmacccle vaccine, and then three very important vaccines that a baby hasn't gotten yet. That's mmrzels, mumps, your bella verisala, chicken pox, and hepatitis A.

00:43:05
Speaker 2: So erin take it away.

00:43:07
Speaker 1: Let's start with MMR right, please, Okay, let's start with the first m which I am designating measles.

00:43:14
Speaker 2: It is always measles.

00:43:15
Speaker 1: Yeah, I mean it was the first of these vaccines to be developed.

00:43:19
Speaker 2: Oh okay, that makes sense. Yeah, it is the big one.

00:43:23
Speaker 1: It is the big one. Yeah, and so yes, measles is the first M in the MMR combo vaccine, and it's caused by a virus, the most contagious virus ever discovered.

00:43:33
Speaker 2: Period period one.

00:43:35
Speaker 1: Infected person can transmit the virus to fourteen to eighteen susceptible people.

00:43:41
Speaker 2: You'll probably know what do.

00:43:43
Speaker 1: You get that?

00:43:45
Speaker 3: That means for every one person who has measles, fourteen to eighteen people will get infected from that one person if they're all not vaccinated.

00:43:56
Speaker 1: Yep, yeah, this the are not I think that most of us are now familiar with that term thanks to COVID. Yeah, fourteen eighteen.

00:44:04
Speaker 2: Yep.

00:44:05
Speaker 1: It is staggering. It is staggering. Measles is airborne, and infectious particles can hang out in the air for hours, even after the infectious person has left. Infected individuals can spread measles to others before symptoms appear, which also contributes to its contagiousness. These symptoms include a runny nose, cough, red watery eyes, and the classic rash starting on the face and neck and then spreading throughout the whole body. Measles is not a mild illness. It can lead to complications such as blindness, encephalitis, ear infections, pneumonia, and death. Even if a child's course of illness seems minor, Measles can induce immune amnesia, which makes their immune system forget how to fight off infections that they've previously been exposed to, and this leaves them vulnerable to other pathogens.

00:44:58
Speaker 3: It wrecks you, It really really does.

00:45:02
Speaker 1: Before the measles vaccine was developed in the nineteen sixties, this infection was one of the most dreaded childhood infections and has throughout history led to enormous death tolls, especially in more isolated communities or ones under oppressive colonial rule like Fiji, which in eighteen seventy five, as you heard in our firstan account, lost a quarter of its population to measles.

00:45:26
Speaker 2: A quarter of its population.

00:45:29
Speaker 1: Before the vaccine was introduced in nineteen sixty three, the measles virus caused an estimated two point six million deaths each year globally, two point six million every year.

00:45:43
Speaker 3: I yeah, it's you can't you can't wrap your head around that, ye, kind of just destruction.

00:45:48
Speaker 1: Between two thousand and twenty twenty three, the measles vaccine as estimated to have prevented sixty.

00:45:55
Speaker 2: Million deaths due to measles.

00:45:57
Speaker 1: Sixty million deaths that didn't happen because we had this vaccine.

00:46:01
Speaker 3: Right, And that's not even just like that's not infections, because there's plenty of other complications that can arise just after an infection. That's sixty million people who are alive today because they had a measles vaccine.

00:46:15
Speaker 1: And because measles is so infectious, is so contagious, vaccine coverage has to be really high to prevent outbreaks and thus deaths, and unfortunately that isn't always achieved due to access and or choice, and each year the death toll remains high. The WHO estimates that over one hundred and seven thousand people, mostly unvaccinated or under vaccinated children under five, died of the disease in twenty twenty three alone. That's so sad, so many children. Yeah, and this is why measles infections often serve as a canary in the coal mine, because that indicates that vaccination coverage has waned, and we'll talk more about the current outbreak that's ongoing seems to be growing in the US. We'll talk about that next week. And I think just to really hammer home how infectious measles is and how much the vaccine protects you, there was a study from Johns Hopkins that found that unvaccinated children between the ages of five and nine were one hundred and seventy times more likely to contract measles compared to their vaccinated peers.

00:47:24
Speaker 3: Yeah, I mean, the measles vaccine is incredibly effective. Like one single dose is like ninety three percent effective, and two doses is like ninety seven percent effective.

00:47:33
Speaker 2: Yes, like it is. It is incredible.

00:47:36
Speaker 1: It is incredible. Yeah, yeah, Okay, moving on to the next m which is mumps. So the other this is the other m in MMR. Mumps is also a viral infection. It's transmitted via direct contact or airborne particles. Symptoms include body aches, headache, general cruddy feeling, low grade fever, and often these like big painful swellings of the prodded salvary glands.

00:48:00
Speaker 2: Down here, yeah, down here.

00:48:03
Speaker 1: Mumps can also lead to swelling of the testes and ultimately infertility.

00:48:07
Speaker 2: Yeah.

00:48:08
Speaker 1: Before the vaccine, mumps used to be incredibly widespread, and during World War II, the US Surgeon General called it one of the most disabling infectious diseases among new recruits. It really spreads well in a crowd, as do most diseases, many disease. Yes, Since the introduction of the vaccine in the late nineteen sixties, mumps cases have declined over ninety nine percent. Wow, over ninety nine percent since its introduction in nineteen sixty seven.

00:48:34
Speaker 2: That's incredible, Aaron, It is all right.

00:48:37
Speaker 1: Moving on to R This is rubella the R and MMR Lubella is also caused by a virus transmitted also through airborne droplets. Symptoms can consist of rash, fever, nausea, conjunctivitis, and swollen lymph glands behind the ears and in the neck. For most people who get infected, the illness is mild and self contained. But this virus poses a huge risk to pregnant people. This virus can cross the placenta and infect the fetus, which in eighty percent of cases will result in the death of the fetus or congenital Rubella syndrome, Yeah, which is very severe, very severe before the rubella vaccine was developed, cases of rubella numbered into the millions. For instance, in the US, in the nineteen sixty three to nineteen sixty five rubella epidemic, there were twelve and a half million cases of rubella in the US alone, in the US alone, leading to twenty thousand cases of congenital rubella syndrome, eleven thousand miscarriages and therapeutic abortions, and two thousand newborn deaths.

00:49:42
Speaker 2: Jeez, Louise Aaron yep.

00:49:45
Speaker 1: Just in a couple short years, Just a couple of years, yeah, right, and right before the vaccine came out. And since the introduction of the vaccine in nineteen sixty six, cases of rubella, congenital rubella syndrome, and miscarriage and neonatal death attributable to rebella have declined sharply in countries that have incorporated the vaccine into their schedule. Yeah, all right, MMR is done.

00:50:08
Speaker 3: Far.

00:50:09
Speaker 2: I'm sorry, Press the way you just breezed through all that air, I mean, the numbers way heavily. I know they do, don't they?

00:50:19
Speaker 1: All right, there's more. Next is Vericella. So Veriicella is also known as chicken pox. It's an infection caused by the Veriicella zoster virus. It's spread through the air from respiratory secretions or from the fluid of skin lesions, and also direct contact. Symptoms include fever, a general creddy feeling, and of course the classic itchy chicken pox rash which sucks.

00:50:41
Speaker 3: It sucks, can confirm speaking from experienced the vaccine. Oh, I do remember, yeah, And then I remember I think that I think my mom said we had appointments to get our chicken pox vaccine or something. It was like the year I think that the vaccine came out, but then we just got sick instead.

00:51:00
Speaker 1: I'm older than you, so my one hole. But you know, I think chicken pox. We have this idea of it potentially as this like mild infection, but it is not right. Here are severe complications that can arise after chicken pox infection or during chicken pox infection. And these things can be like secondary bacterial infections, pneumonia, encephalitis, and permanent nerve damage or visual impairment. Newborn's, elder adults, and immunocompromised individuals are especially at risk of severe infection with this virus and even if you have a mild infection in childhood, the virus will hide out in your nerve cells where it can become reactivated later in life and cause shingles. Before the vaccine was introduced, vericella caused and estimated four million cases in the US alone every year, leading to ten thousand, five hundred to thirteen thousand, five hundred hospitalizations and one hundred to one hundred and fifty deaths, primarily in children. Yeah, access and uptake of this vaccine is not very high globally, and so we do still see a substantial number of cases and complications. One hundred and forty million infections with four point two million hospitalizations and four th two hundred deaths around the world each year. Again hard to take.

00:52:23
Speaker 2: In, Hard to take in, erin a last at disappointment, Last disappointment.

00:52:28
Speaker 1: Hepatitis a HEPA like HEPB is a viral infection that affects the liver. It's spread fecal orally, often through food or water contaminated with the feces of someone who is infected with the virus. Symptoms include things like fever, feeling cretdy, appetite, loss, diarrhea, nausea, jaundice dark urine. Usually this infection is self limited, but it can progress to fulminent hepatitis, which can lead to death. There is no treatment for hepatitis A.

00:52:56
Speaker 2: None. None.

00:52:58
Speaker 1: But even though a vaccine has been available since nineteen ninety five, global cases of hepatitis A have been on the rise, with nearly one hundred and sixty million infections estimated in twenty nineteen.

00:53:10
Speaker 2: Yeah, huge number, huge number.

00:53:12
Speaker 1: And this rise is in part due to the vaccine not being included in routine immunizations in many countries which often have high rates of the disease.

00:53:21
Speaker 3: Yeah, so that was a lot, But that is also the vast majority of all of the childhood vaccines because by your twelve month visit, they're almost all done. Yay, because by twelve months, your baby is strong enough to kick when you try and give them their shots.

00:53:42
Speaker 2: Just saying.

00:53:44
Speaker 3: Usually at the fifteen month visit there's a fourth dose of the d TAP. That's usually when that one is given, and then at eighteen months is when you'll get the second dose of hepatitis A. That's a two dose vaccine series. But after that, after that eighteen months, it's annual flu in covid shots until a kid reaches school age, which is four to six depending on when you start school, and to enter kindergarten, kids will get a couple of other shots. They're all just booster doses essentially of the shots that they've already gotten. So it's a fifth dose of the d TAP, a fourth dose of the poliovirus, and a second dose of mmr and vericella, which sometimes can be given as one MMRV shot, So cool combined in one.

00:54:30
Speaker 1: Combo shots are great.

00:54:31
Speaker 3: I love combo shots. I wish we had more of them. Then during the rest of most of the rest of elementary school, it's just annual flu in COVID like just like what adults get, until age eleven to twelve years old, which is when kids will get their first dose of t DAP. We've said we'll mention it. It's basically just a different version of DTaP. It has like slightly different concentrations of things, okay, but t DApp has a booster for tetanus as well as protessis and the diphtheria in there. And then they'll also get two vaccines they haven't gotten yet, and that is HPV and the meninjacccle vaccine. So Aarin tell us about these to close us out on the childhood vaccination schedule.

00:55:21
Speaker 1: You know, I am so passionate about the HPV vaccine. It's it's yeah, so life saving, it is so life I mean they all are r I know, yes, but.

00:55:32
Speaker 3: I think it's because this one is the most recent for us, and so it feels like must.

00:55:36
Speaker 1: And it's also like uphill battle because of the way it was marketed, et cetera, et cetera.

00:55:40
Speaker 3: Yes, well it prevents cancer, which is so cool. All right, Sorry, we're getting ahead of ourselves.

00:55:46
Speaker 1: HPV, also known as human papillomavirus, is of course a virus a group of viruses that cause cervical cancer and also warts. This group of viruses caused nearly seven hundred thousand cases of cancer globally in.

00:56:01
Speaker 2: Twenty nineteen twenty nineteen.

00:56:03
Speaker 1: One year, including all cases of cervical cancer that were tested, and also upwards of eighty percent of anal cancers, up to fifty percent of penile cancers, thirty percent of orofer angeal cancers, also vulgar and vaginal cancers, lourngeal cancer, and more. Cervical cancer alone caused an estimated three hundred and fifty thousand deaths in twenty twenty two. This is a preventable can.

00:56:30
Speaker 3: Cancer, Yes, preventable cancer and so many I think that also gets under attension, yes, not enough attention is the array of cancers that can cause so many other times, I mean eighty percent of all anal cancers HPD associated.

00:56:46
Speaker 2: Yes, Hello, vaccination lastination all right, Meninja cockle.

00:56:52
Speaker 1: So the menina coccle vaccine protects against a bacterium known as Niceria meningititis, and this bacteria can cause severe infections, mostly meningitis and bloodstream infections. These are most common in children and adolescents. It is spread by respiratory droplets, and an estimated five to ten percent of people carry this bacterium in their nose without it causing illness.

00:57:15
Speaker 2: Just hangs out, just hangs out there.

00:57:17
Speaker 1: But when it does cause illness, it is often very severe, and even with antibiotic treatment, about ten to fifteen percent of cases result in death. Yeah, yep. It has also been on the rise in the US since at least twenty twenty one, with an estimated four hundred and thirty eight cases of invasive meningococcal disease in the US alone in twenty twenty three, and antibiotic resistance is on the rise.

00:57:42
Speaker 2: Yeah, me, Ninjococcus is no joke. It is no joke.

00:57:46
Speaker 3: Yes, but that is the childhood vaccine schedule.

00:57:52
Speaker 2: I also feel like.

00:57:53
Speaker 1: We should mention, or maybe I want to mention, is that if you didn't get one of these vaccines as a child, or if you didn't get them as the number of doses that we just mentioned, talk to your doctor. Yeah, and because these are not like things that you can only get in a narrow window. Even with HPV, they're expanding the age.

00:58:14
Speaker 2: It's up to forty two.

00:58:15
Speaker 3: Now you can get it covered by insurance up to age forty two for HPV vaccine used to only be twenty six. The new macacco vaccine didn't really exist when a lot of us that were adults were kids. And so we're that's also recommended for adults either over a certain age or if you have asthma or other commorbidities. So, yeah, like all of these vaccines, talk to your healthcare providers because yeah.

00:58:36
Speaker 1: If you're not sure if you were vaccinated, like, yeah, exactly.

00:58:41
Speaker 2: Love it. Okay, So it was a lot. It was a lot.

00:58:44
Speaker 1: Yeah, we just ran through what feels like a million, a million different vaccines and diseases, and you know, we've got all these facts and numbers that are swirling around in our heads. Yeah, it's a lot to take in.

00:58:56
Speaker 2: It can't be And we wanted to.

00:58:58
Speaker 1: Go through each of the disease is in the childhood vaccine schedule so that there's a sense of what each vaccine protects you from and what life was like or what life is like without these vaccinations. Because we have a short memory as a society, most of us have never met someone who was paralyzed from polio, or whose child died of measles, or who lost their pregnancy due to a rubella infection. And thank goodness for that, right Like that.

00:59:26
Speaker 2: Is amazing that we can say that, yes.

00:59:30
Speaker 1: Vaccines are in part a victim of their own success. They have been so effective in preventing disease and death that we take them for granted. Tragedies are obvious, we can easily observe them, we can see them, but a tragedy averted is nearly invisible. If you look around. A high school graduation in the US in the nineteen thirties, you would immediately see the impact of polio, crutches, wheelchairs, empty chairs. But if you do the same thing today, you'd don't see how many kids are alive and healthy and excited to start their future lives because of vaccines, because they didn't die or suffer permanent injury from polio or measles, or rubella or vericella or hybrid eptheria or tetanus or so many other vaccine preventable diseases.

01:00:16
Speaker 2: It's actually like genuinely making me cry.

01:00:18
Speaker 3: I know, it's like because that's an image we don't ever think about looking around us and thinking how incredible it is that we are all here and alive.

01:00:28
Speaker 2: Yes, and I mean it's not we do. We just take it for granted.

01:00:33
Speaker 1: We take it for granted so so much.

01:00:36
Speaker 2: Yeah.

01:00:36
Speaker 1: And also in this country, we take it country.

01:00:39
Speaker 2: Especially because that's not true everywhere. It's not.

01:00:42
Speaker 1: Yeah, in the US, in and other high income countries. Vaccines have given us profound freedom from infectious disease, and one of the greatest tragedies is that people use that freedom to choose not to vaccinate and hopefully.

01:00:59
Speaker 2: With our disease by disease.

01:01:00
Speaker 1: Shpiel of the facts. You know. We've shown you how deadly these diseases can be without vaccines, and why vaccines are the best way to ensure your child's health. But not every person can be vaccinated, or not every child who is vaccinated actually mounts an immune response. Vaccines don't just protect you, they also protect your community. When enough people in a community are vaccinated, these diseases can't spread. That's called herd immunity. But this herd immunity only works when a certain proportion of the population is vaccinated. As that proportion declines, as it has done in recent years, that leaves more people vulnerable to infection and allows outbreaks to happen. Speaking specifically about the US, although I'm sure that this applies elsewhere as well. We are infected with this idea of total freedom. It is what we deserve, it is what we have. This is a free country, mean me, yes, protect you. It's like the people in your immediate circle, like that's yeah, right, we should be able to do whatever we want, whenever we want, just like no consequences.

01:02:13
Speaker 2: Right. But that is simply not true.

01:02:15
Speaker 1: That is not true.

01:02:16
Speaker 2: It is false. It is not the reality of the world.

01:02:20
Speaker 1: No by living in a society by driving on the roads, the public roads that we drive on, but everything we have to abide by certain rules, by a social contract. We should want what's best not just for ourselves, but also for our neighbor. We're not on our own. We all depend on each other, and we are affected by the choices that we make, both individually and collectively. And what we need to do is reconnect with the truth that vaccines are a big part of what gives us this freedom. They don't take it away.

01:02:53
Speaker 3: Right because vaccines are preventing against diseases that spread through populations. They're not something that just affects an individual. Yes, they are not the same as a lot of other medical choices that people make.

01:03:11
Speaker 2: Mm hmmm yeah.

01:03:13
Speaker 1: And to bring it all the way back to what we said at the top of this episode, we understand, We understand the fear, the hesitancy, the confusion, the shame. This is not an easy thing to navigate when the overwhelming amount of conflicting information that is out there about this topic makes it really hard to know what to do, makes it really hard to sift through to find quality information and then recognize it when we find it. How do we even know that that is quality equality.

01:03:44
Speaker 2: Source, especially because most of the quality information is hard to read, hard to get through, yep, and TikTok videos are snappy. Not to again, I'm not just blaming TikTok.

01:03:56
Speaker 1: I don't know, are you though, Eric, No, But one of the biggest battles in this is just knowing who you can trust and where to find this information. And so I think on that note, I would like to bring it to the sources that we used for this episode, and.

01:04:13
Speaker 2: Let's prove you can trust us.

01:04:15
Speaker 1: Yeah, Aaron, I have like one million and one sources for them.

01:04:22
Speaker 2: That's wonderful.

01:04:23
Speaker 3: I don't have as many as I expected, but I also have a million old episodes that we did that I went back to my notes on so.

01:04:31
Speaker 1: Yes, largely, I would say, just like to not go through these million and one I used a lot of the for the individual diseases. I used a lot of the who website has a great for most of the diseases, great websites for pre vaccine mortality rates, and also like the symptoms, what this vaccine does when it was developed, all these types of things. And then also I found really just broadly speaking, there's a paper from twenty twenty four from the Lancet and I'm going to find it right now, and it is by Shaddock at All, twenty twenty four and it is titled Contribution of Vaccination to Improved Survival and Health Modeling fifty years of the Expanded Program on Immunization And just as like a bottom line of this, this paper found that since nineteen seventy four, vaccination has averted one hundred and fifty four million deaths around the world. Wow, And that includes one hundred and forty six million deaths among children younger than five. So vaccination saves lives millions and million, millions and millions of lives.

01:05:45
Speaker 3: I also use the World Health Organization and the CDC for a bunch of things, including like the side Effects from Vaccines. We'll link to that site that they have.

01:05:55
Speaker 2: The paper though, that I.

01:05:57
Speaker 3: Wanted to give a shout out to, was from two twenty twenty one in the journal Vaccines, called Vaccine Technologies and Platforms for Infectious Diseases, Current Progress, Challenges and Opportunities has a lot more deep dive on the different types of vaccines and what we use and why we use it, and those kinds of things, which I think is really helpful. But we have a lot, a lot more sources, so we'll post all of them from this episode and all of our other episodes on our website, this podcast will kill You dot Com under the episodes tab check it out.

01:06:29
