An advisory panel for the Centers for Disease Control and Prevention on Wednesday endorsed the Pfizer-BioNTech coronavirus vaccine for 12-to 15-year-olds, following the FDA's emergency use authorization.

Why it matters: Approval from the CDC panel was the final step needed before inoculations could be offered at any vaccination site for this age group.

• Pfizer has said its vaccine is 100% effective at protecting against COVID-19 in a trial of more than 2,200 children between the ages of 12 and 15.
