Over many years, Kennedy has been clear about his beliefs on vaccines in dozens of interviews, podcasts and social media posts.

At a Senate confirmation hearing for RFK Jr. on Wednesday, there was discussion of abortion, Medicaid, and Covid-19. There was also discussion of onesies.

Warren pointed out that the government financial disclosures Kennedy filed as part of the confirmation process said he had made $2.5 million from a law firm that has sued vaccine manufacturers.
