Abstract
Coronavirus disease 2019 (COVID-19) causes high morbidity and mortality in long-term care facilities (LTCFs). COVID-19 vaccine effectiveness against infection was 81.5% and 81.4% among fully vaccinated residents and staff in LTCFs. The vaccine effectiveness against COVID-19-associated death was 93.1% among residents, and no hospitalizations occurred among fully vaccinated staff.
Highlights
We estimated the effectiveness of COVID-19 vaccines (1) in preventing polymerase chain reaction (PCR)–confirmed severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infections in both residents and staff of long-term care facilities (LTCFs), (2) in preventing COVID-19-associated hospitalization in staff and (3) in preventing deaths in residents as a proxy for severe disease
56 individuals were hospitalized with COVID-19 as their primary diagnosis, of whom 2 were among partially vaccinated and none were fully vaccinated
Vaccine effectiveness was high against both SARS-CoV-2 infection and severe disease in fully vaccinated residents and HCWs in LTCFs in Norway
Summary
High vaccine effectiveness against coronavirus disease 2019 (COVID-19) and severe disease among residents and staff of long-term care facilities in Norway, November 2020–June 2021.
