Recommendations for Prevention and Control of Influenza in Children, 2017 - 2018.

Abstract

This statement updates the recommendations for routine use of the seasonal influenza vaccine and antiviral medications for the prevention and treatment of influenza in children. The American Academy of Pediatrics recommends annual seasonal influenza immunization for everyone 6 months and older, including children and adolescents. Highlights for the upcoming 2017-2018 season include the following:1. Annual universal influenza immunization is indicated with either a trivalent or quadrivalent (no preference) inactivated vaccine;2. The 2017-2018 influenza A (H1N1) vaccine strain differs from that contained in the 2016-2017 seasonal vaccines. The 2017-2018 influenza A (H3N2) vaccine strain and influenza B vaccine strains included in the trivalent and quadrivalent vaccines are the same as those contained in the 2016-2017 seasonal vaccines: a. trivalent vaccine contains an A/Michigan/45/2015 (H1N1)pdm09-like virus, an A/Hong Kong/4801/2014 (H3N2)-like virus, and a B/Brisbane/60/2008-like virus (B/Victoria lineage); and b. quadrivalent vaccine contains an additional B virus (B/Phuket/3073/2013-like virus [B/Yamagata lineage]);3. Quadrivalent live attenuated influenza vaccine (LAIV4) is not recommended for use in any setting in the United States during the 2017-2018 influenza season. This interim recommendation, originally made in 2016, followed observational data from the US Influenza Vaccine Effectiveness Network revealing that LAIV4 performed poorly against influenza A (H1N1)pdm09 viruses in recent influenza seasons;4. All children with an egg allergy of any severity can receive an influenza vaccine without any additional precautions beyond those recommended for any vaccine;5. All health care personnel should receive an annual seasonal influenza vaccine, a crucial step in preventing influenza and reducing health care-associated influenza infections, because health care personnel often care for individuals at high risk for influenza-related complications; and6. Pediatricians should attempt to promptly identify children suspected of having influenza infection for timely initiation of antiviral treatment, when indicated, to reduce morbidity and mortality. Best results are seen when treated within 48 hours of symptom onset.
