Correct answer: A — Two influenza vaccine doses are needed in the first season, at least 4 weeks apart

Children aged 6 months to under 9 years receiving influenza vaccine for the first time should receive two doses at least 4 weeks apart, then annual vaccination. Delaying until 12 months would leave the infant unprotected during the season. The pearl is that influenza vaccine scheduling differs from many routine childhood vaccines because annual strain updates are needed.
