The Centers for Disease Control and Prevention (CDC) has issued the recommendations of the Advisory Committee on Immunization Practices (ACIP) for the 2017-18 influenza season. The CDC continues to recommend routine annual influenza vaccination for all persons aged ≥6 months who do not have contraindications. Standard dose or high dose vaccine is acceptable for adults aged ≥65 years. Among the changes from last year:
- Vaccine viruses included in the 2017–18 US trivalent influenza vaccines will be 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 (Victoria lineage). Quadrivalent influenza vaccines will contain these 3 viruses and an additional influenza B vaccine virus, a B/Phuket/3073/2013–like virus (Yamagata lineage).
- Afluria Quadrivalent and Flublok Quadrivalent are now available for patients aged ≥18 years, and there is an expansion of the age indication for FluLaval Quadrivalent, previously licensed for ≥3 years, to ≥6 months.
- Pregnant women may receive any licensed, recommended, age-appropriate influenza vaccine.
- FluMist Quadrivalent should not be used during the 2017–18 season due to concerns about its effectiveness against influenza A(H1N1)pdm09 viruses in the US during the 2013–14 and 2015–16 influenza seasons.
