Vaccine stocks tumble: Moderna, Novavax, Pfizer fall after top FDA official resigns over RFK Jr. anti-vax views

Stocks of major vaccine makers dropped on Monday after the Food and Drug Administration’s (FDA) top vaccine official Dr. Peter Marks resigned, citing conflicts with Health and Human Services (HHS) Secretary Robert F. Kennedy (RFK) Jr. over his views on immunization. RFK Jr. is a longtime critic of vaccines, and has a history of making controversial and scientifically inaccurate claims.

Shares of Moderna (MRNA) slid 11%, Novavax (NVAX) was down 6%, BioNTech (BNTX) fell about 7%, and Pfizer (PFE) dropped 2% in early trading.
