In an interview on March 18, 2024 RFK Jr. spoke about his views on vaccines

"Anybody who wants to take a vaccine, I'm not going to get in their way. If you want a vaccine, if you want to vaccinate your children, those vaccines will be available. But I am going to tell the truth to Americans. I'm going to do for the first time good science, right?"

"When I was a kid, there were three vaccines, and I took all three. There were three that were mandatory, that were recommended, which essentially means mandatory. And I was compliant. Today there are 72 and we're going up to now I think 77 or 79 with the you know the annual COVID vaccines."

"So and not one of those, with the exception of the COVID vaccine, not one of those vaccines has been tested prior to licensure in placebo-controlled trials which are required for every other medication. What I would do as president is I would require placebo control trials, long-term safety trials."

"They will look at efficacy, they will look at safety, they'll look at the long-term impacts and be able to inform Americans for every age cohort whether that vaccine is likely to avert more problems than it causes for individuals. And I think everybody ought to have that choice. All of my policies are going to be science-based with the best science that's available."

"I don't know enough about the measles outbreak to say that. I don't know whether the measles outbreak is vaccine-strain measles. I don't know what age cohort it's landing. And the problem with the measles vaccine... is that it's a leaky vaccine. It doesn't provide sterilizing immunity, which means for a large percentage of the people who get that vaccine, it will wane at old age."

"So I think within 10 years, and I may be wrong about the exact numbers, but I think ultimately about 20 to 30% of the people who get that vaccine, it wanes. So they're now vulnerable to measles at old age, which is not good."
