ABSTRACT
In April 2021, we assessed mRNA vaccine effectiveness (VE) in the context of a COVID-19 outbreak in a skilled nursing facility. Among 28 cases, genomic sequencing was performed on 4 specimens on 4 different patients, and all were classified by sequence analysis as the Beta (B.1.351) variant. Adjusted VE among residents was 65% (95% confidence interval 25-84%). These findings underscore the importance of vaccination for prevention of COVID-19 in skilled nursing facilities.
