A new study determined Pfizer's vaccine for children doesn't provide significant protection.

According to the New York State Department of Health, the effectiveness plunged from 68% to 12% in kids ages 5-11 during the Omicron surge.

Public health officials believe it may be because of the lower dosage that age group was given. New York city is set to end its mask mandate March 7.
