CDC: Pfizer vaccine reduces omicron infection risk 31%-59% in children age 5-15

In a study of 1,364 children aged 5-15, two doses of the Pfizer COVID-19 vaccine reduced the risk of omicron infection by 31% in those under 12 and 59% in older children, the Centers for Disease Control and Prevention reported today. CDC said the study reinforces the importance of vaccination to keep children and teens protected from severe disease, noting that another recent study found the vaccine 92%-94% effective against COVID-19 hospitalization in adolescents during the delta surge and 74% effective against hospitalization in younger children during omicron.
