Two states issued their own vaccine recommendations on the same day, and in Maryland's case it was the first time the state has ever done so. The Maryland Department of Health released 2026-2027 vaccine schedules for children and adults under authority created by a new state law, while the Illinois Department of Public Health adopted fall respiratory virus immunization guidance developed by its own expert committee.
The practical consequence for households is that the answer to a simple question, which vaccines are recommended for my child, now depends partly on which state you live in. Maryland's children's schedule lists 18 vaccines by age from birth to 18. Its adult schedule lists 16, organized for pregnancy and for age bands from 19 to 49, 50 to 64, and 65 and older.
