Pfizer Inc. and partner BioNTech SE asked U.S. health regulators to authorize three doses of their vaccine for children under 5 years.

The request Wednesday to the Food and Drug Administration comes after the companies said last month that three doses of the shot were 80% effective at preventing symptomatic COVID-19 and generated a robust immune response in children ages 6 months to 5 years old.
