Robert F. Kennedy Jr., a vocal vaccination skeptic, said Tuesday that President-elect Donald Trump has asked him to "chair a commission on vaccination safety and scientific integrity" and that he has accepted.
Both Trump and Kennedy have spread fringe theories linking vaccines to autism in children, an idea that medical experts overwhelmingly reject and have warned is endangering public health by discouraging parents from immunizing their kids.
Trump has tweeted previously that he knew a child who developed autism after receiving immunizations, but he did not provide evidence for that claim.
Scientists have debunked the link between vaccines and autism. But Kennedy, the son of the late U.S. attorney general, believes there is connection and has advocated for parents to be allowed to opt out of vaccinations for their children.
