Robert F. Kennedy Jr. wants to revisit federal vaccine recommendations, take fluoride out of public water and boost access to raw milk, among other goals.

Pfizer's stock dropped 4.3 percent while Moderna's fell 3.1 percent and Novavax saw a 2.8 percent dip in its stock Friday morning.

Days before the election, Kennedy posted on social media that a Trump White House would advise all U.S. water systems to remove fluoride from the public water supply, which goes against public health recommendations yet jibes with a large number of people who question the safety of fluoridating water.

Kennedy Jr. suggested that the Covid-19 virus was engineered to give Chinese and Ashkenazi Jewish people some sort of immunity.
