Pfizer and BioNTech’s two-dose COVID-19 vaccine provided very little protection for children aged 5 to 11 during the wave of omicron infection in New York, according to a study published on Monday (Feb. 28). The study has not yet undergone peer review.
The New York State Department of Health found that the effectiveness of Pfizer’s COVID-19 vaccine against SARS-CoV-2 infection plummeted from 68% to 12% for kids in that age group during the omicron surge from December 13 through January 24.
Protection against hospitalization dropped from 100% to 48% during the same period.
