Association between early influenza vaccination and the reduction of influenza-like syndromes in health care providers

A comparison of 2 different influenza seasons (2013-2014 and 2014-2015) where early vaccination among health care providers (HCPs) in the latter was the difference. Differences in leave of absence because of influenza-like illness (ILI) (52 vs 15 [total number of leave of absence issued], P <.001) and total days of lost work (218 vs 68, P <.001) were found for the 2013-2014 and 2014-2015 seasons, respectively. An association between earlier influenza vaccination among HCPs and a reduction in ILI, leave of absence, and days of lost work was found.
