Indications and Guidance for the Current Flu Season

OP will forecast Due or Behind starting August 1st through June 30th of the following year. During July, the patient's Flu vaccination status is considered Current.


  • Influenza vaccines are not licensed for administration to infants younger than 6 months and should not be used in this age group.
  • Vaccinating children 9 years of age or older: The forecast calls for one influenza vaccine per season. One and done.
  • Vaccinating children 6 months through 8 years of age:
    • 2 doses are needed if they have received fewer than 2 doses of any trivalent or quadrivalent Influenza vaccine (IIV or LAIV) prior to July 1, 2021. The interval between the 2 doses should be at least 4 weeks (28 days).
    • Only 1 dose is required if they have previously received 2 or more total doses of any trivalent or quadrivalent influenza vaccine (IIV or LAIV) prior to July 1, 2021. The 2 previous doses do not need to have been received during the same Influenza season or consecutive Influenza seasons.

Grace Period: ACIP allows a grace period of 4 days (i.e., vaccine doses administered up to 4 days before the recommended minimum interval or age can be counted as valid). However, the grace period should not be applied to live virus minimum intervals or any other 28-day minimum intervals. Day 1 is the day before the day that marks the minimum age or minimum interval for a vaccine. If today is Friday the 5th, the earliest 4-day grace period date would have been Monday the 1st.
