Abstract
We report an outbreak of severe acute respiratory syndrome coronavirus 2 501Y.V2 in a nursing home. All nonvaccinated residents (5/5) versus half of those vaccinated with BNT162b2 (13/26) were infected. Two of 13 vaccinated versus 4 of 5 nonvaccinated residents presented severe disease. BNT162b2 did not prevent the outbreak, but reduced transmission and disease severity.
