Vaccination dramatically reduced COVID-19 symptomatic and asymptomatic infections in St. Jude Children s Research Hospital employees compared with their unvaccinated peers, according to a research letter that appears today in the
Journal of the American Medical Association.
The study is among the first to show an association between COVID-19 vaccination and fewer asymptomatic infections. When the Pfizer-BioNTech BNT162b2 vaccine was authorized for use in the U.S., the vaccine was reported to be highly effective at preventing laboratory-confirmed COVID-19.
