Vaccine Panel Overhaul Weighs on Moderna, Pfizer, BioNTech Shares

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.
