In a P.1 COVID-19 outbreak in long-term-care, vaccine effectiveness against SARS-CoV-2 infection was 52.5% (95%CI 26.9-69.8%) in residents and 62.2% (95%CI, 2.3-88.3%) in staff. VE against severe illness was 78.6% (95%CI 47.9-91.2) in residents. Two of 19 vaccinated resident cases died. Outbreak management required both vaccination and infection control measures.
