LOS ANGELES — With coronavirus cases and hospitalizations rising in Los Angeles County, officials are voicing new confidence in the effectiveness of the updated COVID-19 booster shot.
New data has found that the updated COVID-19 vaccines offer “significant additional protection” against symptomatic infection in people who were previously vaccinated or boosted with the older formula.
While the efficacy of the shots varied depending on a person’s vaccine history, data published in a recent U.S. Centers for Disease Control and Prevention Morbidity and Mortality Weekly Report found consistently boosted defense across all adult age groups.
