** Vaccine stocks conclude 2024 with mixed results, with Pfizer and Moderna set to end the year in the red, while Novavax and BioNTech are on track to snap a two-year losing streak

** Shares of Pfizer have fallen 7.6% this year, trading at less than half their value at the height of the COVID-19 pandemic

** Shares of Moderna are down 58.6% this year, on track for third straight year of losses

** Shares of vaccine makers have come under pressure after President-elect Donald Trump picked anti-vaccine activist Robert F. Kennedy Jr. to head the Department of Health and Human Services

** U.S.-listed shares of German vaccine maker BioNTech also fell more than 10% after the announcement; BNTX shares, however, are up ~7% this year

** NVAX is on track to end the year in the green, with shares up 65%; shares of the company hit a near two-year high after it struck a licensing deal worth at least $1.2 billion with Sanofi for its COVID-19 vaccine
