Science Vs - Vaccines: Does Europe Do Them Better?

Episode Date: January 15, 2026

The U.S. just made a big change to its vaccine recommendations, cutting back on the number of shots it will routinely recommend for kids. The government says it wants to "better align" with countries like Denmark. But is following Denmark’s lead a fairy tale come true — or a nightmare in slow motion? Plus, we find out what this new schedule could mean for kids’ vaccines in the U.S. We hear from Professor Jens Lundgren and pediatrician and researcher David Higgins. Find our transcript here: https://bit.ly/ScienceVsVaccineSchedules  In this episode, we cover: (00:00) The growing turmoil around vaccines in the U.S. (02:20) Why did the CDC change its vaccine recommendations?

Hi, this is Merrill Horan in for Wendy Zuckerman, and you're listening to Science Verses. This is the show that pits facts against filling up babies with shots. Today on the show, vaccines. In the U.S., there's been a ton of turmoil around vaccines. The Department of Health and Human Services is being led by a longtime vaccine skeptic, Robert F. Kennedy, Jr. He's been accused of firing the head of the CDC for not rubber-stamping his vaccine policy. He's also added a ton of vaccine skeptics to this big vaccine advisory committee. And President Trump has chimed in here saying that we've been giving kids way too many shots.

They pump so much stuff into those beautiful little babies. It's a disgrace. And last week, the CDC announced a big change, saying they've got new vaccine recommendations for kids. New guidance from the CDC reducing the number of vaccines recommended for children. They have scaled back the number of vaccines. vaccines now only recommending 11 vaccines. The CDC is now saying that some shots that were given to kids routinely instead should be given on a case-by-case basis, like to quote high-risk groups. And to back up these new recommendations, the government has pointed to what some other

countries are doing. They say that when you look at the U.S. versus similar countries, some of them don't give kids nearly as many shots. And there's one country in particular that's gotten to. pointed to a ton. Denmark. Denmark. I hear Denmark a lot. They're a pretty healthy country. Why shouldn't we copy Denmark? Yeah, the CDC seems to me modeling its new recommendations on Denmark. So, is this a fairy tale come true for the U.S.? Or is it more like a nightmare? Today we're going to find out why do some other countries recommend fewer vaccines than the U.S.?

Does it make sense to follow their lead? And we'll look at what the fallout could be. Because when it comes to vaccines, there's a lot of beautiful little babies. And then they're science. Science versus is coming up after the break. I was guilty of multiple skin care crimes. Two counts of sleeping and makeup. One count of using disposable wipes.

I knew my routine had to change. So I switched to Garnier-Missler water. It gently cleanses, perfectly removes makeup, and provides 24-hour hydration. Clear away the evidence with the number one Missler Water Worldwide by Garnier. Welcome back. This is Merrill Horn. I'm here with my fellow senior producer, Rose Rimler. Hey, Rose. Hi, Merrill. So, we're talking about this vaccine news today. What have you been seeing about this?

I haven't been following it super closely. I have been following it a little bit. And one thing I saw on social media that was going around was this infographic where there were like two cartoon babies. One cartoon baby is. surrounded by syringes, you know, a handful of syringes, but the other cartoon baby is completely encircled with syringes, I guess, full of vaccines. And I think it was from Trump. And it says, like in the text it says, in the U.S., babies get 72 shots. And I was like, is that true? That does seem like kind of a lot. Yeah. But the graphic was just so ridiculous, too. So, yeah, I've been following it. I don't know. I don't really know what's true.

it's not true. We looked into that one. So, yeah. I mean, it is true that babies get more shots today than in the past. Than in the past. Yeah. But like, but they're not getting like 72 shots. So the number we did the, you know, we added them up.

And it seems like if you add up all the individual shots that someone gets by the time they're 18 years old, including getting, you know, a flu shot and COVID shot every year, then you get 72. Oh, that's where they got that from. Yeah. So it's sort of true, but it's not that babies are getting 72 shots. Right. And then if you just look at the number of diseases that kids are getting vaccinated against, of course, that number is much lower, right?

Because it doesn't include all the booster shots. So how many diseases is it? So before this change, the CDC was recommending that every kid get vaccinated against 17 diseases. Now it's just 11. So they took away six vaccines that they recommend for everybody. Which ones? Okay, so the recommendations changed for hepatitis A and B, meningitis, RSV, rotavirus, and flu. Okay.

Wow. And they had actually already stopped recommending the COVID shot last year for every kid. So now those ones are only recommended to either high-risk groups or, quote, based on shared clinical decision-making, unquote. The, you know, which is basically the idea that you have a conversation with your doctor and decide together instead of it being routine. Do more work to get the shot. Yeah, it's not as automatic.

And they do say that insurance will still cover these vaccines if people want them. But, you know, on the whole, yeah, it makes it more messy. Okay, Merrill, so in addition to the babies encircled with syringes, it is apparently bogus, another thing I saw, I was reading a little bit about these changes that came down. And in the article, it said, this will bring us in line with a... Denmark's policy and I was like, Denmark. Like, I mean, that's interesting because I think a lot of people in the U.S. like idolize Scandinavia and like everything they do is better thought out and smarter and

better for children than whatever we're doing in the U.S. Especially when it comes to health care. We're often like, oh, look at these Scandinavian countries we should do that they're doing. Yeah. That's like this utopia of everybody on their wooden bicycles or whatever. So, yeah, I mean, that made me sort of stop and think. Like, why Denmark, basically. Yeah, exactly.

Let's start there. Like, a big reason the U.S. government says that it's making this change, it's not because there's a bunch of new vaccine science saying that, like, vaccines aren't safe anymore. It is because we're trying to match up with what other countries are doing, like Denmark. So to find out how Denmark thinks about all of this, we went directly to the source. the Danish I had for breakfast. Mawp Wamp. Merrill, go to your room.

Unacceptable punning. We actually talked to Jens Lundgren. He's a professor of... He's a Danish? Yes, he's a professor of infectious diseases at the University of Copenhagen. And Yens actually advises the Danish health authority on which vaccines to recommend to the Danes.

Do you remember the first time you heard that the U.S. was kind of using Denmark as a model, and what you thought when you heard that? No, I felt that was very surprising to make that analogy and then just uncritically adopted. So that was surprising to me, I have to say. Yeah, do you know why we used Denmark in particular? That's probably more for you to answer than me.

Right. So, yeah, I went back and did my homework. And so there was this memo from the White House in December where President Trump praised death. Denmark, along with a few other high-income countries, basically for just doing fewer childhood vaccines. And then Trump called for a review on the U.S. schedule to see if it should make any changes. And, of course, you know, they did. So let's, I want to understand, yeah, like, why does Denmark recommend vaccinated against fewer diseases?

Yeah, I have that question. Yeah. And Yen said that, you know, a bunch of things factor into this decision for them of whether or not to recommend a vaccine. So how effective the vaccine is, the cost. And then there's how common the disease is. So basically, you have to do a math problem to consider, you know, if you're trying to decide if everyone needs a certain vaccine, you need to think about how many cases of a disease you're going to prevent by vaccinating everyone in the population. We would argue that if the numbers that we need to vaccinate is extraordinary large in order to

reduce the risk for one person for contracting a disease. Then that's a legitimate discussion to have about whether it's worthwhile to induce a vaccine, although it is effective. Yeah, and so this is one reason why Denmark might not want to vaccinate every kid. Some diseases are pretty rare. So an example here that I think is helpful is meningococcal disease, which can cause meningitis. And this is one of the vaccines that the CDC just changed. the recommendations around. So if you look at the number of people who get meningitis every year,

it is less than one case in every 100,000 people, both in the U.S. and in Denmark. So what do you know about meningitis, by the way, Rose? That's the one that college students get when they live in the dorms, right? And it makes your brain swell. And it's actually very, very dangerous. Is that right? Yeah. Yeah, exactly. It's really terrible. It's often caused by a bacteria, and it can affect tissues around your brain, which can lead to this huge immune reaction, where it can basically make your brain puff up so much that you die. So when people get it in the U.S., maybe 10 to 15 percent of them will die, sometimes it happens really quickly, like within 24 hours. But, you know, that hasn't been enough for Denmark to recommend the vaccine for every kid. Here is Yenz.

It is scary, yes, and it's a serious condition, but it's also rare. And that, for having a Koggle vaccine, the question will become, do you vaccinate blanket-wise? So everybody? Or are you focusing your vaccination efforts if there's an outbreak? And we have chosen the latter. So basically, they'll go and vaccinate people surrounding the person that gets it. Yeah, that's the idea, kind of a more targeted approach there. I talked about this with another researcher, though, David Higgins.

He's a pediatrician and researcher in Colorado. and he said that if you want to give the vaccines, like only when you've got an outbreak, then like in order for this to work, you really have to have your little, like, healthcare ducks all in a row. You have to catch these diseases really fast. You have to quickly be able to find all of their contacts

and that ring around the cases to vaccinate them and get vaccines to them. That requires a health system, and a public health system that is really well-resourced, that doesn't have a lot of gaps and cracks in it where things can fall through. That requires really good access to health care. We don't have those things in the U.S.

Yeah, I could see how that would be harder to do here. There's a lot more cracks. Yeah, it's more fragmented, right? We don't have a national health care system like they do. And just a side note, the system doesn't work perfectly in Denmark either. So in 2024, Denmark had 26 known cases, of meningococcal disease.

And they did this contact tracing and found more than 100 people who were close contacts of people who got it and told them to get vaccinated. But they were only able to confirm that half of those people actually got the vaccine. And, you know, the fact that the U.S. has been vaccinating kids for meningitis routinely, it saved lives.

So one modeling paper estimated that the vaccine prevented about 500 meningitis cases and 54 deaths in young people. So that was over a period of about 15 years. Mm-hmm. Another thought I have, Merrill, is if we're talking about how rare diseases, sometimes diseases are rare because everybody or many people are vaccinated. Yeah. Yeah, no, that's another good point, right? We're kind of ignoring that fact when we just look at how rare it is today. Well, could you argue that Denmark is benefiting from the U.S.,

vaccinating more people in our population. So it's just suppressing meningitis around the world generally? Well, actually, a lot of other European countries do vaccinate for meningitis. And in some cases, they do it even earlier than the U.S. does. So Denmark is a freeloader off everyone else's vaccination status. Basically. So, yeah, that's kind of one factor that Denmark is looking at, though, you know, how common a disease is. Another reason, and I talked about with the ends for like why they might not recommend a vaccine for every kid is about how deadly the disease is. So an example of this would be rhodovirus.

Yeah, what is that, by the way? Like, I've only heard it in this context. I have never heard of that disease. I had no idea either before this episode. But, yeah, it's, well, first of all, it is really, really common. So in the U.S. before the vaccine, basically every kid was getting rhodovirus by the time they were five years old. Ah.

And this one, it infects your GI tract and can cause really bad diarrhea. And it can get so bad that it will land kids in the hospital. And so, yeah, I asked Yens about why they don't recommend vaccinating against this. And he said a lot of factors go into it, but one thing is that it is treatable. It's not something, at least in all contexts, that we see as a terribly serious disease. again, they're confident that a kid who has a bad case of rhodovirus can get to a hospital and be treated. Yeah, the health care system really matters for that too, right? And then, you know, if you look at the numbers in the U.S., vaccinating has kept a bunch of kids out of the hospital.

So the CDC is calculated that the vaccine prevents 62,000 emergency department visits and 45,000 hospitalizations every year from rhodovirus. which to me does make me glad that my kids are vaccinated against it, even if it's not going to kill them. I don't want them to go to the ER. Well, yeah, I mean, that's the thing with kids in getting sick. Kids get sick a lot, and you just hope that your kid is going to have an okay case and get over it, and this is part of life.

But you don't know if your kid's going to be the one that gets really, really sick from something. And if someone in the family has to go to the hospital, that's really disruptive and scary for the kid. And like, I'm thinking about vaccines for childhood diseases that are typically fairly not life-threatening, but very unpleasant. Yeah. So one that comes to mind for me is the chickenpox vaccine, which did not exist when I was little. Me neither, yeah. One of my earliest memories is, like, being in the bathtub and some kind of weird solution they give for being covered in soars, you know, pox. And being in the bathtub, my mom next to me and me just crying because I was so miserable.

Yeah. feeling awful and I got it, both my brothers got it, and the whole family was just like, so we were all fine and we got through it, but it's like, it'd be nice to not have that happen. Like, I don't see, like, that's good that you don't have to like be sick and covered in pot, which can scar you too. So, like. Right. Where now it's just this vaccine, which, by the way, is still recommended for everyone.

Yeah, and I'm jealous. I'm like, you kids today, you don't even know what we have to go through. It makes me think of as just how many sicknesses my young kids are already getting every single winter. It's so brutal. It's just like one after another, after another after another. Yeah, everyone on the team who has little kids is like constantly like someone's kid is always sick at science versus. And I'm just sort of imagining a parallel universe where a rhodovirus was also this one that like all the moms would like complain about on the group chat. Like oh, my kid has like diarrhea for like a week. And like that sounds like a bad alternate universe. Like, I'm going to be in this one where they got some stuff.

Like, it's like oral vaccine. So my kids got something squirted into their mouths. I kind of barely even remember this happening. But yeah, now it does sort of feel like we're going backward with this rotavirus vaccine to this time where some kids might now be missing out on it. But yeah, just to go back to the idea that, you know, we want to just be, like, emulating another country's vaccine schedule. A lot of the people we talked to said that it just does. doesn't make sense to do this, like, plop one country's vaccine schedule into another's. Here's David.

You can't copy and paste the vaccine schedule from another country and expect it to work in the same way that it does in a different context, like the U.S. Why, Merrill? Because diseases are diseases. It's just biology. Borders are made up. Stop trolling me. Convinced me.

Well, like, for one, which country do you pick then, right? Because this idea that we need to align with other countries that do fewer vaccines has been around for a while. One of the things that's brought up is like, okay, the U.S. is an outlier, right? We have vaccines for 18 diseases. Denmark has vaccines for only 10. And Japan, 14. And Germany, only 15.

So we are an outlier and we need to align with peers. Not only are those countries cherry-picked, because I can count other countries that have a very similar schedule to ours. like Canada, Australia, New Zealand. But also, the fact that we have coverage for more diseases is not evidence of a problem. That's backward. It's not a competition to see how few diseases we can prevent. I don't know.

Some people seem to think that. But no, I mean, another way to, I'm thinking back to that baby, surrounded by the needles infographic, we talked about in the, beginning, like the baby on the left with fewer syringes around it had a lot of like gaps in its shield. And the baby on the right was like fully shielded. So you could completely switch how you look at that. Yeah. Yeah. We should make our own infographic. And so and then to pick, you know, Denmark and then ignore, you know, Canada and Australia and New Zealand is a little, you know, is a little random. Other peer countries. Yeah. And, and.

And then, of course, there are countries that are adding vaccines to their schedule, including, Dun-da-da-da-da-da-da-denmark. So, yeah, they just added RSV during pregnancy, this awful respiratory virus. You know, the UK just added varicella, chickenpox, to their list. So this idea that the U.S. needs to, like, match up with some other country, it's a moving target anyway. Some of them are trying to match up with us, at least previous us. Yeah, actually, we heard that, too. And yeah, so we actually reached out to experts in other countries to ask them what they thought of these changes in the U.S.

And they all told us that it was surprising. One of them told us, quote, it is like watching a train wreck in slow motion, unquote. Yeah, that's kind of what it feels like, for sure, from the inside, too, being in a train wreck in slow motion. Yeah. And, you know, we did reach out to the Health and Human Services Department. they basically defended this decision. They said in a statement that, quote, evidence from peer develops nations

shows high vaccination rates can be achieved through trust in public health, education, and strong doctor-patient relationships, unquote. And they also pointed out the access thing, saying that, quote, insurance will continue to cover more vaccines for children in the U.S. than in peer nations, unquote. All right. So after the break, what's next?

What's going to happen from here? Yeah. We're all going to be staggering around with our rotavirus. Coming at our buttholes. After the break.

Hi, Merrill. So we're talking about this big change in vaccine recommendations, and we just heard some reasons why experts don't think it makes sense for us to cosplay as Denmark. They're like, black licorice is gross. Yeah. But the other thing we

wanted to know is like how much do these changes actually matter? Like how big a deal is this? I talked about this with David Higgins, who you heard from before. So on a scale from one to 10, how big of a vaccine emergency is this? Well, I would say that this is an eight. Huh. An eight or nine. Whoa. Okay. Now, here's why. I think that a 10 would be the, uh, a, uh, a 10 would be the, uh, no access to some life-saving vaccines that parents want to choose for their children or that we want to get as patients. This, in some ways, does still preserve some choice. Because you parents still can get these if they want them. Is that right? That's right. Except it is a big deal. And here's why. Because over time, this is likely to decrease the availability and access for people.

parents who want to vaccinate their children. So yeah, David's worried that even if parents still technically have access to these vaccines, these changes have injected some confusion into the system since, you know, it's a lot easier to just say like, here's your list of shots, go and get them, then to have people figure out, like, is my kid high risk or should we do this thing where I need to talk to my doctor? So one example where this does get really confusing is RSV, which is really terrible. Here is David. R.SV is just a horrible, nasty virus that every pediatrician, every winter, we are just swimming in RSV. Kids get super snoddy with it. And like we, I have admitted more kids to the hospital, put more kids on oxygen, and had more complications

than any, any other disease by far. And these are healthy kids, right? We had a particularly bad RSV season several seasons ago. And I remember walking. into the emergency department for a shift several times. And walking in, I mean, the waiting room is filled with kids on oxygen that hadn't even been seen yet. And so, yeah, it's terrible. And one thing that's exciting is that we do have these new ways of protecting babies against it. But it's, so let me tell you about how it works, because it is really complicated and it's taken me forever to wrap my head around it.

You mean how the vaccine works? Yeah, for starters. The vaccine itself is kind of a weird one. So the vaccine was approved in 2023 for pregnant people. But then at the same time, we got a separate treatment, not a vaccine, but something called monoclonal antibodies that babies can get after they're born. So if the mom didn't get the shot when she was pregnant, then the babies can take the antibodies and these both work pretty well. Okay. Okay. So in the old recommendations, you had RSV at the top of the You know, primo placement saying babies should get these antibodies right away when they're born, specifically if the mom hadn't been vaccinated or they didn't know her vaccine status.

But now when you look at the new recommendations and you look at where RSV is listed, it's in this whole new category that's further down of kids who are, quote, high risk. And this could mean that the kid has chronic health problems. But it could also mean that your mom didn't get the vaccine. Like that makes you high risk too. Okay. And that actually could be a lot of kids because the vaccine is only recommended

if you're in a certain stage of pregnancy at a certain time of year. Well, so it sounds like what you're saying is because the vaccination of people during pregnancy is not universal by any means, a lot of kids are going to be born without having been vaccinated while in the womb, which makes them a candidate for like a high risk.

But yeah, it's not clear maybe that your kid is high risk just because you didn't get the vaccine. You have to kind of, you have to know that. It's tricky, yeah. And, you know, David pointed out that this detail is kind of tucks into a footnote in this new schedule. Parents are going to look at the schedule and say they're not going to read the footnote. How this is described is in a footnote, they're going to see the schedule, the nice colors and say, oh, my child's not high risk. Yeah. I had a normal pregnancy.

I had, you know, we left the hospital after two days and everyone said your baby's healthy and great, why should they be getting this? So that's my concern with that one. Yeah, that is really confusing. Yeah. And, you know, this point about confusion, we're already seeing this play out. Like for me, Rose. Even you? Yeah, I am one of these confused parents, not because of RSV, but actually a different vaccine.

So, okay. So last week, I took my son to the pediatrician. He's two. And the doctor was basically like, good news, you don't need any vaccines today. So he would have needed the hepatitis A vaccine, but now that's not on the schedule for everyone. And she told me, you know, that's fine because there's barely any hep A in the U.S. anyway. Okay. And in the moment, I was relieved because I didn't have to like watch my toddler scream cry. But then I left the appointment not really. sure what's a thing. So I asked David about Hephae. Hepatitis A is a good example where prior to using the vaccine, especially kind of through the 90s, it was spreading through our communities. Now, what the vaccine

has done is it stopped that spread. Just as recent as the 90s though, it was out there. That's right. That's right. And so we, now, because so many people in the community, especially kids are protected with the vaccine, we don't see it spreading routinely through the community.

That doesn't mean that it's not out there. It is still out there and can still absolutely come right back. So vaccines are victims of their own success, right? We use it. It works. And then people start questioning why it's necessary. Yeah. Because they don't see it anymore, because the vaccine worked. And unfortunately, these diseases will come back. when we stop vaccinating. They're being held at bay with vaccines. They're not eradicated. So what does that mean for your two-year-old, Meryl?

Are you going to go and get him the shot? Yeah, actually. I'm like, okay, I need to put this on my to-do list for the next time we go back, especially because hepatitis A is still really common in other parts of the world, and I don't want to have to worry about him like getting a shot later, if he's traveling,

it just makes it more messy. We are a very interconnected world where one of these diseases is only a plane flight away and can be introduced to a community that has a vaccination rate that's way too low. And what's going to happen? Well, I think of it like dry forest and sparks being thrown into the dry forest.

Eventually, that spark's going to land in the wrong place and it's going to start a wildfire. And, you know, going to a different disease now, we are seeing some of this with resurgence, with measles in the U.S. right now, right? Like, we've got that spreading, especially in these unvacc communities. And it's happening in other countries, too, like Canada.

They've lost their status as a country that's eliminated measles. And we might too. And that's going on, even though the official recommendations still tell you to get your kid vaccinated for it. And so, yeah, you know, with these new recommendations, there's this concern that parents won't know what to do, that a lot of the vaccines sort of feel honest. So I asked David, should parents still get all of these vaccines for their kids?

I still recommend all of the vaccines that are on the American Academy of Pediatrics vaccine schedule. That is what I'm looking to. That is what I am recommending for my families. That is what I'm telling other clinicians and vaccination providers to look at. And so that hasn't changed with these new recommendations from the federal government. Yeah. So the AAP still basically abides by the old schedule that they're, the CDC used to have before this recent change.

David says that, you know, best case scenario is that people do that. They keep following that old schedule. But that's not necessarily what he thinks is most likely. Oh, I wish I had a crystal ball and I don't. Right. I am concerned that this is one step among more steps to come that are going to continue to erode trust or availability of vaccines. I don't think we're done here.

I think in this next year, we're going to see more and more things happen. They're going to make parents question that are going to make parents hesitants, not because of the science changes. And unfortunately, I think what we're going to see is when parents want to vaccinate, it's become harder and harder. there are going to be more barriers, more things that they have to overcome to get their kids vaccinated when they want to.
