Shares of leading vaccine makers fell on Monday following the U.S. decision to replace all members of the Advisory Committee on Immunization Practices (ACIP), a key CDC advisory panel. Moderna (NASDAQ: MRNA) slid 1.2%, Pfizer (NYSE: PFE) dropped 1%, and BioNTech (NASDAQ: BNTX) eased 0.9%, as investors braced for potential changes in vaccine approval dynamics.
Why the ACIP Shake-Up Matters
Restoring Trust: In an opinion piece, Robert F. Kennedy Jr. called ACIP a “rubber stamp” that failed to scrutinize vaccine safety, especially for infants and pregnant women.
Impartial Panel Goal: By retiring members appointed late in the Biden administration, the CDC aims to install fresh voices free from past conflicts of interest, reinforcing transparency in vaccine recommendations.
Market Impact: Any perceived disruption in the vaccine-approval pipeline or shifts in guidance could dent sales of established COVID-19 and flu vaccines.
