# ACIP reemphasizes the importance of administering 2 doses of vaccine to all children aged 6 months--8 years if they have not been vaccinated previously at any time with either LAIV (doses separated by >6 weeks) or TIV (doses separated by >4 weeks), on the basis of accumulating data indicating that 2 doses are required for protection in these children (see Vaccine Efficacy, Effectiveness, and Safety).
# ACIP recommends that children aged 6 months--8 years who received only 1 dose in their first year of vaccination receive 2 doses the following year (see Vaccine Efficacy, Effectiveness, and Safety).
