Abstract
In a P.1 coronavirus disease 2019 (COVID-19) outbreak in a long-term care home, vaccine effectiveness against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was 52.5% (95% confidence interval: 26.9%-69.1%) in residents and 66.2% (2.3%-88.3%) in staff. Vaccine effectiveness against severe illness was 78.6% (47.9%-91.2%) in residents. Two of 19 vaccinated resident case patients died. Outbreak management required both vaccination and infection control measures.
