What influenza vaccines may be used in children for the 2024-25 influenza season?

All six 2024-25 season influenza vaccines approved for children are trivalent, containing two influenza A strains and one influenza B strain.

There are five injectable inactivated influenza vaccine (IIV) options for children. Four egg-based IIVs and one cell culture-based (ccIIV), all given as intramuscular (IM) injections, are approved for children age 6 months and older:

• Afluria (CSL Seqirus): 0.25 mL/dose for age 6 through 35 months; 0.5 mL/dose for age 3 years and older
• Fluarix (GSK): 0.5 mL/dose for age 6 months and older
• FluLaval (GSK): 0.5 mL/dose for age 6 months and older
• Fluzone (Sanofi): 0.25 mL or 0.5 mL per dose for age 6 through 35 months; 0.5 mL/dose age 3 years and older
• Flucelvax (ccIIV, CSL Seqirus) cell-based (no egg antigen): 0.5 mL/dose for age 6 months and older

One egg-based live attenuated nasal spray vaccine, FluMist (LAIV, AstraZeneca), is an option for healthy, non-pregnant people age 2 years and older: 0.2 mL (intranasal, 0.1 mL in each nostril).
