FDA Authorizes First Covid-19 Vaccines for Young Children

U.S. health regulators cleared for use Covid-19 vaccines from Pfizer Inc. and BioNTech SE and from Moderna Inc. in children as young as 6 months. Some 1½ years after first authorizing the shots for people of older ages, the Food and Drug Administration on Friday expanded use of the vaccines to the nearly 20 million children in the U.S. from 6 months to under 5 years. A national campaign to vaccinate the young children is expected to kick off as soon as Monday, after the Centers for Disease Control and Prevention signs off in the coming days.
