Newest COVID shots are 54% effective in preventing symptoms, CDC finds

Associated Press  

NEW YORK — The latest versions of COVID-19 vaccines were 54% effective at preventing symptomatic infection in adults, according to the first U.S. study to assess how well the shots work. The 54% finding is similar to what’s been reported in other countries, and it’s also about what was reported for an earlier vaccine version, said the Ruth Link-Gelles of the CDC, the study’s lead author. Studies coming out later this year will assess how effective the shot was at preventing symptoms severe enough to send patients to a doctor’s office or hospital, she said. The slow uptake meant that it took longer for researchers to gather enough data to assess how well the shots work, Link-Gelles said.
