    In an observational study involving nearly 440,000 veterans, both the BNT162b2 vaccine and the mRNA-1273 vaccine were highly effective at preventing infection, hospitalization, and death from Covid-19. Infection risks were approximately 21% lower with mRNA-1273 than with BNT162b2. Follow-up included periods when either the alpha variant or the delta variant was dominant.
