The Food and Drug Administration approved a new round of Covid boosters on Monday, that will arrive alongside the seasonal flu vaccine and shots to protect infants and older adults from R.S.V., a potentially lethal respiratory virus.
The Centers for Disease Control and Prevention is expected to follow up on Tuesday with an advisory meeting to discuss who should get the new shots, by Pfizer-BioNTech and Moderna. After a final decision by the C.D.C.’s director, millions of doses will be shipped to pharmacies, clinics and health systems nationwide within days.
The Pfizer shot was authorized in the European Union for ages 6 months and older on Aug. 31.
Covid vaccines are just rolling out in the United Kingdom this week, with the first doses going to the highest risk people in care homes, ages 65 and over as well as health and social care staff members.
