Kennedy met with Donald Trump Tuesday and said the president-elect has asked him to chair a presidential commission on vaccine safety.
"I am totally in favor of vaccines", Trump said during a September 16 debate.
Trump has a history, on Twitter and in debates, of questioning the well-established science behind the US' vaccination program. Trump has assured questioners that he's not anti-vaccine - Kennedy did the same Tuesday - but has also said that they should be more spread out than medical professionals may allow, and not involve "massive" doses.
Kennedy has been among those claiming that preservatives in vaccines are linked to the rise in autism cases, though researchers and the Centers for Disease Control and Prevention say there is no such link.
Scientists have debunked the link between vaccines and autism.
The problem for Trump and the GOP going forward is that this skepticism is something that affects everyone.

He climbed up a tall, nearby structure and then climbed across the lift's guide wire to reach his friend. "The backpack had wrapped around his neck and he was unconscious, dangling 10 feet above the snow".
He said he is "very concerned" that parents may delay getting their children vaccinated as they await the outcome of this panel, which could result in "increased harm, illness and potentially death" of children from diseases that could be prevented by vaccines.
Kennedy, a fellow vaccine skeptic, issued a public apology after referring to vaccine administration as "a holocaust" to children while speaking at the screening of anti-vaxxer documentary "Trace Amounts".
Trump has also raised concerns about vaccines and their health impacts.
Trump indicated support for the debunked theory at a Republican presidential debate in 2015, the Post reported.
"I am totally in favor of vaccines".
In 2014, he edited a book titled Thimerosal: Let the Science Speak: The Evidence Supporting the Immediate Removal of Mercury - a Known Neurotoxin - from Vaccines.
Furthermore, nine CDC studies since 2003 have found "no link between thimerosal-containing vaccines and ASD, as well as no link between the measles, mumps, and rubella (MMR) vaccine and autism spectrum disorder in children", the federal agency said.
