• [Pre-print, not peer-reviewed] A study comparing documented SARS-CoV-2 infections and deaths in Spain to counterfactual model predictions from February 6 to March 28, 2021 estimated that after 70% of long-term care facility residents had been fully vaccinated with the Pfizer-BioNTech vaccine, 74% of COVID-19 deaths and 75% of all documented infections were prevented, and transmission was reduced up to 90%. The authors note that in enclosed populations such as long-term care facilities, high vaccination rates may rapidly control SARS-CoV-2 transmission.
