CDC: COVID-19 Vaccine Reduces Death From Delta Variant 10-Fold

This summer, when the delta variant of the coronavirus became predominant, the risk of infection among fully vaccinated people was reduced 5-fold, and the risk of hospitalization and death was reduced more than 10-fold, according to the Centers for Disease Control and Prevention (CDC). The delta variant had little effect on the incidence rate ratios for hospitalization and death in 13 studied U.S. jurisdictions. The data suggest high, continued vaccine effectiveness against severe COVID-19. “Monitoring COVID-19 incidence by vaccination status might provide early signals of potential changes in vaccine effectiveness that can be confirmed through robust controlled studies,” the agency concluded.
