U.S. health advisers are urging a booster dose of Pfizer's COVID-19 vaccine for kids ages 5 to 11.
The Centers for Disease Control and Prevention quickly signed off on the advice.
The decision opens a third COVID-19 shot to healthy elementary-age kids, just like what is already recommended for everybody 12 and older.
Regulators this week authorized the extra dose to be given at least five months after youngsters' last shot.
CDC's advisers endorsed it during a public meeting on Thursday.
