 Rite Air Corp. RAD, -4.69 said Friday that the COVID-19 boosters for 5-to-11 year olds made by Pfizer Inc. PFE, 2.13 and BioNTech SE BNTX, -3.70 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 Preventions Advisory Committee on Immunization Practices recommended Thursday in favor of kids that age group getting the booster five months after their second dose.
