The data, as reported by The New York Times, followed infection and hospitalization rates of almost 855,000 fully vaccinated kids between 12 and 17, and about 365,000 kids between 5 and 11 from December 13th of last year to January 31st of 2022, notably amid the massive Omicron surge.
It found that in that time period, the vaccine’s efficacy plummeted in both age groups but most precipitously in younger kids. Experts believe vaccine dosage could be to blame.
During the Omicron wave, for younger kids, protection against illness dropped from 68 percent efficacy to 11 percent efficacy.
