Percent reduction in noted outcomes in HCP receiving influenza vaccination. Values marked by an asterisk were statistically significant (P<.05) compared with an unvaccinated control group. Patient mortality data from Hayward and colleagues⁷⁴ are from two different seasons. A multivariate analysis of the study by Lemaitre and coworkers⁷⁵ showed that HCP vaccination was a significant independent predictor of patient mortality.
