The Department of Defense (DoD) generates influenza vaccine effectiveness (VE) estimates each season. The Armed Forces Health Surveillance Branch Air Force (AFHSB-AF) satellite, Naval Health Research Center Operational Infectious Disease Directorate at the Naval Health Research Center (NHRCOID), and the Armed Forces Health Surveillance Branch (AFHSB) all conduct influenza surveillance and perform test-negative case-control analyses to estimate seasonal influenza VE for DoD populations. The mid-season estimates contribute to the aggregate data utilized by the Food and Drug Administration's Vaccine and Related Biological Products Advisory Committee to select the composition of the influenza vaccine for the next influenza season. The full season data provide DoD with direct estimates for force health protection decisions. The 2017-2018 DoD influenza season was predominated by influenza A(H3N2) with varying levels of adjusted overall VE estimates. AFHSB-AF satellite's VE for dependents was moderate at 49% (95% confidence interval [CI]: 42%-55%) for all strains. NHRC-OID's VE among dependents was moderate-high at 63% (95% CI: 50%-73%) for all strains. AFHSB service member VE was low at 18% (95% CI: 4%-30%). These estimates highlight the need for continued influenza surveillance and VE estimate calculations each season among the different DoD populations as circulating strains and VE may change annually.
