Vaccine Dose Considerations for Children Aged 6 Months through 8 Years

  • Children aged 6 months through 8 years require two doses of influenza vaccine (administered ≥4 weeks apart) during their first season of vaccination to optimize response. The 2015–2016 recommendations state that children aged 6 months through 8 years, who have previously received ≥2 total doses of trivalent or quadrivalent influenza vaccine before July 1, 2015, require only one dose. The two previous doses need not have been given during the same season or consecutive seasons. Children in this age group who have not previously received a total of ≥2 doses of trivalent or quadrivalent influenza vaccine before July 1, 2015 require two doses. Children who require two doses should receive their first dose as soon as possible after it becomes available and the second dose ≥4 weeks later.

Considerations for the Use of Live Attenuated Influenza Vaccine and Inactivated Influenza Vaccine When Either is Available

  • Both LAIV and IIV have been demonstrated to be effective in children and adults. But the 2014–2015 recommendations stated that, when immediately available, LAIV should be used for healthy children aged 2 through 8 years who have no contraindications or precautions. The 2015–2016 recommendations no longer give preference to LAIV over IIV in this age group.

Additional 2015–2016 recommendations can be found in Table 1.
