title = "Combined effectiveness of prior and current season influenza vaccination in northern Spain: 2016/17 mid-season analysis",
abstract = "The 2016/17 mid-season vaccine effectiveness estimate against influenza A(H3N2) was 15\% (95\% confidence interval: −11 to 35) in Navarre. Comparing to individuals unvaccinated in the current and four prior seasons, effectiveness was 24\% for current and 3-4 prior doses, 61\% for current and 1-2 prior doses, 42\% for only current vaccination, and 58\% for 3-4 prior doses. This suggests moderate effectiveness for different combinations of vaccination in the current and prior seasons.",
