Study: RFK Jr., Joe Rogan’s Misinformation Campaigns Led To A 38% Increase In Vitamin A Poisoning Last Year

from the real-consequences dept

Early last year, when America’s measles outbreaks were still being counted in three-digit numbers, we talked about how RFK Jr. and his misinformation campaign were making things worse. A lot of focus has been on Kennedy’s anti-vaxxer views, and for good reason. If people would just get the MMR vaccine, and had done so in the last couple of decades while Kennedy has been on his anti-vaxxer crusade, none of this would have happened. We eliminated this disease more than two decades ago. It’s back because of vaccine skepticism and Kennedy, now Secretary of HHS, is perhaps more responsible for that skepticism than any other human being on the planet.

But his misinformation campaign didn’t focus solely on attempts at discrediting a good, effective vaccine against measles. He also spouted bullshit when it came to treatments for the disease. One such example was him touting, in March of last year, a combination of Vitamin A and cod liver oil as treatments for measles. It’s not the first time Kennedy advocated for this, either. He’s been at it since the beginning of the outbreak, and even before. In the wake of his public advocacy for those treatments, others picked up the story and ran with it, notably podcast-bruh Joe Rogan.

The result? According to one study, a massive uptick in Vitamin A poisoning.

The researchers detected two fascinating (albeit alarming) surges in interest. The first occurred in the wake of a March 4, 2025, Fox News interview with Trump’s Health and Human Services Secretary Robert F. Kennedy Jr. During the interview, the infamous anti-vaxxer touted cod liver oil supplements and vitamin A as viable treatments for measles. A second series of spikes surrounded two late March podcast appearances by certified physician and noted vaccine skeptic Suzanne Humphries, who promoted the same two questionable remedies. Neither of Humphries’ interviews involved a government official, but one did occur on the chart-topping podcast of Joe Rogan.

“Between January [1] and March [31,] 2025, America’s Poison Centers reported a 38.7% increase in vitamin A exposures,” the new study noted, citing data published by the poison center about 12 days after Humphries’ appearance on Rogan.

Now, the Harvard study focused strongly on the correlation between media mentions of Vitamin A, online searches from the public indicating interest in such treatments, and the uptick in those diagnoses of Vitamin A poisoning. But, frankly, that misses much of the point. It’s been the public advocates like Kennedy who have fueled this fire, leading other charlatans to get spots on media outlets such as Rogan’s, where they get to further disseminate all of this terrible advice. The fish stinks from the head down and, right now, the head of American health is Kennedy.

The study’s authors did at least make mention of how this is all made worse by having untrustworthy clowns in charge of American healthcare, though not by name.

“Our findings underscore media’s influence on health-seeking behavior during public health emergencies like the measles outbreak,” the researchers noted, “which is particularly concerning when guidance from trusted sources is unclear and may encourage detrimental behaviors.”

We’re on pace to break last year’s measles case count by a long shot and it’s exactly because of misinformation peddlers like Kennedy and cavalier media like Rogan’s podcast being willing to signal boost it all that we’re in this mess.

As of this writing, America has had about 86% of the number of confirmed cases of measles this year as we had last year… and we’re only at the midway point of the year. Infectious diseases don’t spread linearly. They typically spread exponentially, which is exactly what happened last year. The public being actively misinformed, on purpose, is why.
