ABSTRACT

COVID‐19 Vaccine Efficacy and the Evidence on Boosters   [open pdf - 0B]

From the Abstract: "The need for COVID‐19 [coronavirus disease 2019] vaccine booster shots is controversial. Krause et al. and others have argued that need for a COVID‐19 booster for all adults has not been sufficiently established. The EU, UK, Canada, and Israel approved boosters for all adults, but U.S. regulators initially limited booster eligibility, waited nearly two months before allowing, and even longer before recommending boosters for all adults, with public health officials sending mixed messages on booster value. [...] The authors summarize vaccine efficacy against four endpoints: any infection, symptomatic infection, hospitalization, and death for the four principal vaccines used in developed Western countries [...] and evidence for waning efficacy over time, based on review of regulatory submissions and studies which met defined inclusion criteria."
