CDC Study Finds Updated COVID-19 Vaccine 54% Effective

Despite promising effectiveness against symptomatic infection, vaccine uptake remains low in the U.S.

The latest COVID-19 vaccine, updated to target recent variants, is 54% effective at preventing symptomatic infection in adults, according to a CDC study.
Despite the vaccine's effectiveness, uptake remains low, with only 22% of U.S. adults and 11% of children having received the shot.
The vaccine shows promise against the JN.1 variant, currently the most common strain in the U.S., and other circulating lineages.
Future studies by the CDC will focus on the vaccine's effectiveness in preventing severe disease, including hospitalizations.
Health experts emphasize the importance of vaccination, especially for high-risk individuals, to provide added protection against COVID-19.
