RFK Jr. is not a serious person. Don't take him seriously.

Well, president-elect Trump has announced that he will nominate Robert F. Kennedy Jr. to be the Secretary of Health and Human Services (HHS), putting him in charge of most of the nation's public health and medical research.

I can't say strongly enough how unqualified RFK Jr. is for this job. He isn't qualified to come anywhere within a thousand miles of any medical or science-related issue, much less to be in charge of health policy for the whole country. Virtually everything RFK says about science is wrong–actually, it's worse than that, because he speaks with such absolutely certainty, despite being wrong, that he convinces people to take actions that end up hurting themselves. To a normal person, someone not accustomed to lying so boldly, these claims can be convincing.

Since Trump's announcement of the nomination, I've been seeing columns in major media outlets (I'm looking at you, New York Times and Washington Post) saying things like "hey, some of RFK's ideas aren't entirely wrong." 

Just. Stop. Even a broken clock is right twice a day. Don't take RFK Jr., or his nomination, seriously.

I don't want to try to list all of RFK's mistaken views, which would require a book-length column, but here are a few. Just last year he said, on the Lix Fridman podcast, that "there’s no vaccine that is safe and effective," and that the polio vaccine did more harm than good. (Both of those statements are wildly wrong.) In 2005, he wrote a long essay for Rolling Stone and Salon which claimed that thimerosal-containing vaccines cause autism (they don't), and that the government knew about it and had been covering it up:

“The story of how government health agencies colluded with Big Pharma to hide the risks of thimerosal from the public is a chilling case study of institutional arrogance, power and greed.” [quote from RFK Jr.]

The article was full of dramatic claims like this one. The only problem was, all of them were false. Rolling Stone and Salon eventually retracted the article and deleted it from their websites. 

In 2019, Kennedy visited the island nation of Samoa to spread his anti-vaccine message, sponsored in part by his anti-vaccine organization, Children's Health Defense. (The name is highly misleading.) Vaccination rates plummeted, and just a few months later a tragic measles outbreak began, causing 83 deaths and 1,867 hospitalizations. Kennedy published an article afterwards calling it a "mild measles outbreak," and in the same article claims (falsely) that vaccines themselves, rather than measles, caused the deaths.

RFK Jr. is someone who never admits he was wrong, even (or especially) when his mistakes cause the deaths of innocent children. Instead, his conspiracy-addled brain blames someone else.

And that's only a tiny sample of RFK's misinformation. He also loves raw milk, which I wrote about in 2014 and again in 2023. Raw milk sometimes contains nasty bacteria and viruses, but fortunately Louis Pasteur solved this problem in the 1860s, when he invented what we now call pasteurization. As I pointed out in my 2023 piece, bacteria just love raw milk. And you know what else is in raw milk but not pasteurized milk? Cow poop. Just don't tell this to RFK Jr. 

By writing columns saying "RFK Jr. has some good ideas" (which I won't link to, since that's just feeding the beast), media organizations are falling into a trap: they're taking RFK seriously. I'd like to ask these journalists: if Trump nominated a first-grader instead, would you write similar stories? Maybe something like "hey, this nominee has some good ideas about nutrition!" 

Don't do it. This nomination deserves ridicule and scorn, nothing more.

I've written multiple columns (both on this site and at Forbes, my former site) warning about RFK Jr. and his dangerous anti-vaccine craziness, starting with this 2014 piece where I called him out for his efforts to lobby Congress against vaccines. His primary obsession then–and he still has this obsession–was the mistaken notion that thimerosal, a harmless preservative that isn't even used in vaccines today, causes autism. This claim has been thoroughly debunked in multiple studies. 

In 2017, I wrote about "Trump's lovefest with anti-vaxxer RFK Jr." – a lovefest that apparently still continues, seven years later. That column was about Trump's promise to put RFK in charge of a commission on vaccines. Fortunately, that vaccine commission never happened, but today we face a much more dangerous threat, if RFK Jr. is confirmed as Secretary of HHS.

I've also pointed out that Kennedy is one of the "Disinformation Dozen," a group of twelve people who, as reported by the Center for Countering Digital Hate, was responsible for 65% of all the anti-vaccine disinformation online. And earlier this year I asked how he could possibly be so arrogant as to think he's qualified to be President, given that his only claims to fame are his name, which he inherited, and his anti-vaccine notoriety.

My problem with RFK Jr. is not just that he is wrong about vaccines, although that is the most immediate threat to public health. But he's also an idealogue, someone who holds onto his mistaken ideas despite mountains of contradictory evidence, and someone who simply makes up things to "prove" his points. 

And in that quote from him above, where he uses the phrase "institutional arrogance," highlights another danger: RFK Jr. is the one who is arrogant. He believes that he can substitute his own unsubstantiated beliefs for the knowledge of genuine experts, and why? Because he's a Kennedy, a man who has lived a life of great privilege, getting into Harvard as a "legacy" despite being expelled from prep school over his drug use, all the while pretending to be fighting against the system. He is too arrogant to listen to others, or to admit his mistakes.  

So no, I cannot take this nomination seriously. Children will die if RFK Jr. is put in charge of HHS. There are tens of thousands of people who are far, far more qualified than Kennedy, and I hope the Senate will refuse to confirm him. I'm not optimistic, but I hope a few Senators will look at the man's record and treat him with the scorn he deserves.

MMR vaccine (still) doesn't cause autism, new study finds

Nope.

We’re still spending vast amounts of time and money trying to counter the ill effects of a discredited, retracted paper from 1998 that claimed to find a link between the MMR (measles, mumps, and rubella) vaccine and autism. Even after the The Lancet retracted the study, and even after the British Medical Council revoked the medical license of its lead author, Andrew Wakefield, many people continue to withhold vaccines from their children because of a fear that somehow, despite all the evidence to the contrary, vaccines might cause autism. Vaccines, I hasten to add, have saved millions of lives and are probably the greatest medical advance of the past two centuries.

Now another study has appeared to add more weight to the evidence about the safely of the MMR vaccine. The new study by Anjali Jain and colleagues, just published in the Journal of the American Medical Association, looked at a huge number of children–95,727–for evidence of any link between autism and the MMR vaccine.

The results were not surprising, to those who have been following the science. To quote the conclusions directly: 

“Receipt of the MMR vaccine was not associated with increased risk of ASD [autism spectrum disorder], regardless of whether older siblings had ASD. These findings indicate no harmful association between MMR vaccine receipt and ASD even among children already at higher risk for ASD.”

That should settle it, right? But then, dozens of previous studies should have already settled this question. Unfortunately, due to the ongoing activism of anti-vaccine groups such as Age of Autism, (who already attacked this new study) and to conspiracy theorists such as Robert F. Kennedy Jr. (whom I wrote about last summer, and who was campaigning against vaccines in Vermont just last week), misguided claims that vaccines cause autism or neurological problems persist.

Here are the numbers from the new study. The authors compared vaccinated children to unvaccinated children, using a huge database of medical claims that included at least 5 years of followup. (This was an "observational" study, by necessity–it would be unethical to withhold vaccines from children on purpose.) The relative risk for autism in children who had 2 doses of the MMR vaccine (the recommended amount) compared to unvaccinated children was 0.74. In other words, a child was somewhat less likely to be diagnosed with autism if he or she were vaccinated. 

Even more surprising was the relative risk among children who had an older sibling with autism: in this smaller group, children with 2 doses of MMR were just 44% as likely to be diagnosed with autism as unvaccinated children. This statistically significant finding indicates, unexpectedly, that vaccines might actually protect children from autism.

The authors were quick to note that there are other good reasons for this apparent protective effect of vaccines: in particular, if parents of autistic children withheld vaccines from their younger children, this could explain the effect. Why? Because we know that autism has a genetic component, and that if one child has autism, his younger sibling is more likely (because they share many genes) to have autism as well. Jain and colleagues explained that if these parents withheld vaccines–because of fears spread by the anti-vaccine movement–then their children could contribute to the apparently lower rate of autism in children who were vaccinated. The authors couldn’t rule out a protective effect of vaccines, but scientifically it seems unlikely, and they wisely offered an alternative explanation.

So: once again we have a large, carefully conducted study showing that the MMR vaccine does not cause autism, and even finding evidence that vaccinated children have lower rates of autism. Let's hope this study helps to end the anti-vax movement, so that we can soon stop spending time and money trying to refute their long-discredited hypotheses and instead focus on trying to understand the true cause.

Robert Kennedy's Anti-Vaccine Craziness

Robert Kennedy is obsessed with the notion that vaccines cause autism. He’s particularly obsessed with the discredited idea that thimerosal, a preservative used in some vaccines, causes autism. Now Kennedy is about to publish a new book on this topic, and he’s promoting it both in the press and, as described in today’s Washington Post, in the halls of Congress. He’s recently had personal meetings with U.S. Senators Barbara Mikulski and Bernie Sanders to try to convince them to take action based on his claims. Why is it that a scientifically unqualified anti-vaccine advocate can get a private audience with a U.S. Senator? Because he’s famous, that’s why.

Robert F. Kennedy Jr. is part of the most famous family in America. He’s the nephew of a former president and the son of a former senator and Attorney General, both tragically assassinated in the 1960s. Another uncle, Edward Kennedy, was a U.S. Senator for Massachusetts for decades. He gives hundreds of speeches a year, mostly on environmental issues, and he’s been an influential figure in the environmental movement.

But on the thimerosal issue, Kennedy has gone completely off the rails. He authored a Salon.com and Rolling Stone article (jointly published) nearly ten years ago that claimed not only that thimerosal-containing vaccines cause autism, but that “the government” knew about it and had been covering it up. Kennedy wrote then that

“The story of how government health agencies colluded with Big Pharma to hide the risks of thimerosal from the public is a chilling case study of institutional arrogance, power and greed.”

Alarming-sounding stuff. The article is full of dramatic claims like this one. The only problem is, it’s all false.

I’ve been writing and speaking about the anti-vaccine movement for years, including articles in 2009 and 2010 on three landmark vaccine court rulings. As I explained back then:

“Why was thimerosal introduced into vaccines? Well, early vaccines were administered from multi-dose bottles, in which bacteria could grow. In one particularly disastrous incident in 1928, 12 children in Australia died from staph infections after getting the diptheria vaccine from the same multi-dose bottle. After the introduction of thimerosal, bacterial infections caused by vaccination virtually disappeared.”

In the late 2000's, a special vaccine court conducted three lengthy hearings in which the anti-vax advocates were asked to present their best cases. One of the cases focused specifically on the question of whether thimerosal in vaccines cause autism. In that case, the judge concluded:

“The numerous medical studies concerning the issue of whether thimerosal causes autism, performed by medical scientists worldwide, have come down strongly against the petitioners’ contentions. Considering all of the evidence, I find that the petitioners have failed to demonstrate that thimerosal-containing vaccines can contribute to the causation of autism.”

As a lawyer, Kennedy should be able to understand this. The science, which Kennedy apparently does not understand, leads to the same conclusion: in study after study, scientists have found no link between thimerosal and autism, or any other kind of neurological disorder. And as RFK Jr knows, thimerosal was removed from childhood vaccines in the U.S. over a decade ago, and the rate of autism diagnosis continued to rise. This fact alone contradicts his major claim. 

What was shocking to me, the first time I heard Kennedy talk about thimerosal in vaccines, was how absolutely certain he is that he is right. Today's Washington Post article describes a man who remains utterly convinced, despite the mountain of evidence against him.

After Kennedy's Salon.com article appeared, scientists responded quickly and convincingly, pointing out its numerous flaws and distortions. Salon.com tried to fix the problem, issuing five corrections before throwing up their hands and removing the article entirely from their website. Rolling Stone also took down the article. Salon’s editor-in-chief wrote an apology, saying 

“I regret we didn’t move on this more quickly, as evidence continued to emerge debunking the vaccines and autism link. But continued revelations of the flaws and even fraud tainting the science behind the connection make taking down the story the right thing to do .”

Kennedy has steadfastly refused to admit any errors, ever. As of today, his own website still displays the original article, without even the small corrections that Salon.com had made. He’s been embraced by the anti-vaccine movement: he gave a keynote talk at their annual conference, Autism One (prompting this response from one well-known science blogger), and he even spoke at one of Jenny McCarthy’s “Green Our Vaccines” demonstrations.

As Keith Kloor wrote today in his online column at Discover, Kennedy has not only failed to convince the world that he’s right (and the entire scientific community is wrong), but he doesn’t really care. He told Kloor that “if I die poor, then I go down fighting for what’s right.” (This despite the ridiculousness of the notion that the wealthy Kennedy family will ever be poor.)

By ignoring the scientific evidence that shows that thimerosal and vaccines have no link to autism, Robert Kennedy has placed himself firmly in the camp of conspiracy theorists and cranks. He’s also demonstrated breathtaking arrogance. He believes that despite his lack of scientific training, he knows the truth that every scientist who’s studied this issue has missed. 

Even worse, Kennedy is using his fame to spread anti-vaccine misinformation, which has contributed to an alarming rise in the number of infectious disease outbreaks here in the U.S., including major outbreaks of measles and whooping cough. Though I doubt he will listen to me (he’s ignored everyone else), Kennedy needs to take a hard look at the harm he’s causing to defenseless children, the elderly, and cancer patients, and anyone else with a weak or compromised immune system. His advocacy of bad science will cost lives, if it hasn’t already.

When I've heard Kennedy talk about environmental topics, where I agree with him almost completely, I’ve been impressed by his passion and his seeming command of the issues. But having heard him speak about thimerosal and vaccines, I now realize that he’s a dangerous idealogue, willing to distort the truth so thoroughly I can’t believe a word he says. The only solace I can take from today’s Washington Post article is that Senators Mikulski and Sanders don’t believe him either. Both of them brushed him off. Next time, they shouldn’t bother giving him an audience.
