Health chiefs ‘confident’ nasal flu vaccine for children is effective


CDC Advisers Recommend Against Use of Nasal Spray Flu Vaccine in 2016-2017 The CDC's Advisory Committee on Immunization Practices has voted against use of the live attenuated influenza vaccine (LAIV) during the upcoming flu season, citing low efficacy among children during the past three seasons. The quadrivalent LAIV, given by nasal spray, was estimated to be just 3% effective against any flu virus among children aged 2 to 17 years during the 2016–2017 flu season, according to preliminary data from the U.S. Influenza Vaccine Effectiveness Network. In contrast, the effectiveness of the inactivated influenza vaccine, given by injection, was estimated at 63% in this age group. In a news release, the CDC notes the potential implications for clinicians who've already ordered vaccine for the upcoming season. Pediatric providers in particular may be affected, given that the nasal spray was used in about a third of child flu vaccinations in recent years. The agency says it will work with vaccine makers in the coming months to ensure the supply. Dr. Deborah Lehman of NEJM Journal Watch Pediatrics and Adolescent Medicine commented, "This recommendation from the CDC's advisers, supported by the American Academy of Pediatrics, comes as providers are preparing for influenza season. Influenza remains the most commonly occurring vaccine-preventable disease, and routine immunization — this year with the inactivated, injectable vaccine — will prevent illness, hospitalization, and death."
