Pfizer and BioNTech's two-dose Covid 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 Monday.
The New York State Department of Health found that the effectiveness of Pfizer's vaccine against Covid infection plummeted from 68% to 12% for kids in that age group during the omicron surge from Dec. 13 through Jan 24. Protection against hospitalization dropped from 100% to 48% during the same period.
