In a COVID-19 outbreak in a long-term care home, the effectiveness of the vaccine against SARS-CoV-2 infection was 52.5% in residents and 66.2% in staff members. The vaccine demonstrated 78.6% effectiveness against severe illness in residents. However, two vaccinated residents still died during the outbreak.
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.
