Robert F. Kennedy Jr., a prominent anti-vaccine advocate, is running for president as a Democrat. Our SciCheck team has combed through his recent interviews to identify and correct some of his most common health claims in a three-part series. In this first installment, we address several of his talking points about vaccines.
Studies have found the rate of autism is the same in vaccinated and unvaccinated children. But the false claim that vaccines are associated with the disorder persists. A prominent spreader of COVID-19 misinformation wrongly told legislators in Pennsylvania that autism is virtually nonexistent among the unvaccinated, citing the Amish population.
Recent research suggests that gender dysphoria is likely caused by a combination of factors, including hormone exposure before birth. But social media posts make the baseless claim that it could be caused by a vaccine containing DNA from an aborted fetus of the opposite sex. There is no scientific evidence for such a claim, experts said.
Clinical trial data for Pfizer’s maternal vaccine to protect babies from RSV support the vaccine’s safety and efficacy, according to a vote by an FDA advisory committee. The FDA could soon approve the vaccine. But a popular social media post makes misleading claims about the trial findings.
An international initiative called the Big Catch-Up aims to increase vaccination among children who have missed routine vaccines during the COVID-19 pandemic. In describing the project, Chelsea Clinton did not say it was time to “force-jab every unvaccinated child in America,” nor will the project impose mandatory vaccinations, contrary to claims.
Several European countries have reported an early spike of group A strep infections, mostly among children, including cases of rare but deadly bacterial infections. There is no evidence the increase is being caused by nasal spray flu vaccines, as social media posts baselessly suggest. Flu vaccination may even indirectly prevent strep A.
Tetanus vaccines can prevent deadly disease in infants, but a video circulating on social media is spreading old, unfounded rumors that discourage immunization.
Sudden Arrhythmic Death Syndrome, or SADS, has been studied for decades and is caused by genetic heart problems. But social media posts suggest, with no evidence, that SADS is related to COVID-19 vaccines.
The Centers for Disease Control and Prevention says it “recommends that children get four doses of polio vaccine.” But Rep. Marjorie Taylor Greene, when speaking against a potential fourth dose of the COVID-19 vaccines, wrongly suggested that the CDC doesn’t recommend four shots of the polio vaccine.
Infectious disease experts say low vaccination rates, resistance to protective measures such as wearing a mask and the highly transmissible delta variant are driving the current surge of COVID-19 cases in the U.S.
