Rite Air Corp. said Friday that the COVID-19 boosters for 5-to-11 year olds made by Pfizer Inc. and BioNTech SE are available at its drug stores and at Bartell Drugs, which it owns. The booster for that age group was authorized by the Food and Drug Administration earlier this week, and the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices recommended Thursday in favor of kids that age group getting the booster five months after their second dose. Rite Aid appointments for getting the booster can be made Friday by a parent or guardian. Rite Aid’s stock slumped 4.4% in midday trading. It has plunged 63.2% year to date, while shares of rival CVS Health Corp. have slipped 9.8% and the S&P 500 has declined 19.4%.
