An outbreak of severe acute respiratory coronavirus virus 2 (SARS-CoV-2) infections among hospital personnel with high mRNA vaccine uptake. (20th September 2021) - Tene, Yael
Abstract: Real-world studies have demonstrated impressive effectiveness of the BNT162b2 COVID-19 vaccine in preventing symptomatic and asymptomatic SARS-CoV-2 infection. We describe an outbreak of SARS-CoV-2 infections in a hospital with high vaccine uptake. We found a low secondary attack rate (7%), suggesting low infectivity of vaccinated persons with vaccine breakthrough SARS-CoV-2 infections.
