Booster shots of the Pfizer-BioNTech and Moderna vaccines are not just preventing infections with the contagious omicron variant — they are also keeping infected Americans from ending up in the hospital, according to data published Friday by the Centers for Disease Control and Prevention.
The extra doses are 90% effective against hospitalization with the variant, the agency reported. Booster shots also reduced the likelihood of a visit to an emergency department or urgent care clinic. The extra doses were most effective against infection and death among Americans 50 and older, the data showed.
