Just as she was about to take responsibility as principal investigator for a prestigious international European project on a new radiation therapy, death called Elke in.Background and objectives Influenza vaccination rates among medical students (MSs) are below the standards recommended in hospitals where influenza vaccination is not mandatory. We carried out a comparative study in two Spanish university hospitals to reassert this fact and evaluated the impact on vaccination rates of a specific program aimed at promoting influenza vaccination among MSs.Methods A descriptive cross-sectional study was performed describing influenza vaccination rates and motivations for vaccination during the 2017/18 campaign among MSs in two hospitals affiliated to the same university. We subsequently performed a community-based intervention study during the 2018/19 campaign evaluating the impact of a strategy for promoting influenza vaccination, comparing the hospital where the intervention took place (hospital A) with the one where it did not take place (hospital B).Results During de 2017/18 campaign the overall influenza vaccination rate was 44.8%, with no differences between hospitals A and B (difference 3.9%; 95% CI -4.36-12.16; p-value = .4). During the 2018/19 campaign, vaccination rate increased to 76.4% in hospital A, with significant differences compared with the previous campaign in the same hospital (29.8%; OR 5.00; 95% CI 3.14-8.3; p-value = .0001) and with that observed in hospital B in the same campaign (21.1%; 95% CI 13.38-28.82; p-value less then .001).Conclusions Influenza vaccination rates among MSs in two Spanish university affiliated hospitals were below the recommended standards. A new reproducible strategy for promoting influenza vaccination with a specific a
