About 750,000 Pennsylvania children are expected to become eligible for Pfizer’s COVID-19 shot after U.S. regulators expanded the use of the two-dose vaccine to 12- to 15-year-olds, according to state health officials earlier today. The state Health Department said vaccine providers should follow their existing policies for vaccinating minors, which requires parental consent in Pennsylvania. Gov. Tom Wolf has said he will lift a statewide mask mandate once at least 70% of Pennsylvania adults are fully vaccinated. Statewide, about 45.6% of people aged 18 and older have been fully vaccinated as of today, according to the U.S. Centers for Disease Control and Prevention.
