CHARLOTTE, N.C. — Pfizer says kid-size doses of its COVID-19 vaccine are safe and nearly 91% effective at preventing infections in elementary school children.
Details of the study were posted online Friday as U.S. regulators consider opening vaccinations to youngsters 5 to 11.
The shots could begin early next month if regulators give the go-ahead.
If the FDA authorizes the low-dose shots, the Centers for Disease Control and Prevention will make the final recommendations on who should receive them.
Full-strength Pfizer shots already are authorized for anyone 12 or older.
