New York CNN —Shares of prominent vaccine makers plunged Thursday after President-elect Donald Trump announced his pick of Robert F. Kennedy Jr. to be the next secretary of the Department of Health and Human Services. An hour before the market closed Thursday, as news reports of Trump’s choice began trickling out, Covid-19 vaccine maker Moderna dipped as much as 6%, and Pfizer fell almost 2%. Novavax, which created a protein-based Covid-19 vaccine, fell almost 6%. Last week, Kennedy said he would “immediately” begin studying vaccine safety and efficacy but promised to not “take vaccines away from anybody.”Other vaccine-related companies also felt the fallout. Over the past year, Pfizer stock has dipped 11%, and Moderna stock has plunged 46%.
