Rapid Evaluation of COVID-19 Vaccine Effectiveness against Symptomatic Infection with SARS-CoV-2 Variants by Analysis of Genetic Distance

Based on 78 vaccine efficacy or effectiveness (VE) data from 49 studies and 1,984,241 SARS-CoV-2 sequences collected from 31 regions, scientists analyzed the relationship between genetic distance of circulating viruses against the vaccine strain and VE against symptomatic infection.
