What Comirnaty Is and How It Works

Comirnaty is an mRNA vaccine that uses messenger RNA to instruct cells to produce a harmless piece of the virus spike protein, helping the immune system recognize the virus later. Pfizer's official product information describes it as a COVID-19 vaccine for preventive use. Pfizer, 05/19/2026

The product matters because many U.S. readers still encounter COVID vaccination through pharmacies, clinics, and physician offices. The FDA's vaccine advisory process remains the key U.S. regulatory backdrop for any updated seasonal formulation. Precaution, 05/2026
