Follow-Up: Robert F. Kennedy Jr. and Vaccines

Last week, I wrote an article strongly condemning Robert F. Kennedy Jr.âs stance on vaccines. In a nutshell, he believes in an elaborate and ridiculous conspiracy theory that scientists all over the world, but especially at the Centers for Disease Control and Prevention, have been lying about the safety of vaccines. He claims that thimerosal, a preservative now used only in one specific kind of flu vaccine, is destroying the brains of our children.

He believes this despite a vast amount of evidence that heâs grossly wrong. Despite test after test, a link from thimerosal to autism has never been shown. But Kennedy chooses to ignore the huge number of researchers who say this and instead focuses on a cherry-picked few, including some with somewhat, ah, shaky credentials.

While Iâve written about Kennedy once or twice before, the fact that he was the keynote speaker at an anti-vaccination (and generally anti-science alternative medicine) convention was what prompted me to write what I did. That, plus my editor, Laura Helmuth, asked me to. She had seen Keith Kloorâs article about Kennedy over at Discover and knew this was up my alley. I thought it was a good idea, and there you go.

Not long after my post went up, the emails came in ⦠from Kennedyâs office. They contacted Helmuth asking if I would speak with Kennedy to correct some errors in my post. Helmuth relayed the request to me. I laughed and told her no thanks; Iâve dealt with conspiracy theorists like him before and knew what a brain-melty experience that phone call would be (as, unfortunately, Kloor found out first-hand). Instead, I told her, have his office write down where they think I was wrong with corrections, and Iâd look them over to issue corrections as needed. This is what I did in the case of an article dissecting the selling out of science by the Canadian government a few weeks ago. (As I expected, the Ministry of Science and Technology sent me nitpicks, with the substance of my claims left unchallenged.)

What happened next in this saga still has me chuckling wryly and shaking my head. Kennedyâs office declined to write and enumerate any of my supposed errors but wanted to call instead. Helmuth agreed to this and decided to take Kennedyâs call herself. What unfolded was eerily as I predicted. Kennedy ranted at her for the better part of an hour. At one point he claimed more than one scientist supports him. Interestingly, when Helmuth contacted one of these scientists, he said Kennedy âcompletely misrepresentedâ him. Another scientist she contacted said much the same thing.

Shocker. I knew that would be the case. Listening to Kennedyâs radio show and reading his articles leads to an all-too-clear conclusion: When it comes to vaccines, he has all the signs of a crackpot. He ignores (or dismisses) evidence that contradicts him, he clings to cherry-picked (or quote-mined) evidence and clearly wrong evidence that supports him, he imagines vast conspiracies, he says scientists at the CDC are criminals, ad nauseum. His history is full of him saying such things.

As Helmuth notes at the end of her article, Kennedy was only able to make one even marginally tenable claim about my article being wrong: He said he wasnât anti-vax but acknowledged vaccines had saved millions of lives and was actually âpro-vaccine.â But I disagree. Saying in one breath that vaccines have done good but then in another attacking them and increasing fears of them based on nonsense puts him squarely in the anti-vax camp. Itâs like saying that most UFO cases are just misidentified normal things, but the ones we havenât identified are definitely alien spaceships that come here to stick probes in our various orifices. Acknowledging one aspect of reality and then claiming absurdities does not make you pro-science.

When it comes to medicine and health, this kind of thinking is dangerous. Thereâs a measles outbreak in Wales, and itâs been tied to baseless vaccine fears. In Auckland, New Zealand, a child nearly died from tetanus recently. His parents didnât vaccinate him because they had read online that vaccines might cause autism. Theyâre horrified at their mistake and want to warn other parents: "There are a number of myths out there, and it's really easy to get sucked in.â In 2010 in California there was a terrible pertussis outbreak, and 10 infants died from it.*

People are getting sick, and some are dying due to preventable diseases. Itâs awful, and the only way to stop it is to get the real information out to people and speak out against those who misinform them.

Correction, June 13, 2013 at 18:15 UTC: The California pertussis epidemic in 2010 was originally stated as occurring in 2013. My apologies for this oversight. A synopsis of the epidemic is available at the NCBI website, and pertussis is still a scourge around the world today.
