Background: during 2008-12, France and Europe experienced large measles outbreaks, involving also healthcare workers (HCW). We aimed to estimate the vaccination coverage (VC) of measles among medical residents of the University of Aix/Marseille, in South-Eastern. Methods: in March 2013, we conducted a cross-sectional study among all medical residents of the Medical Faculty of Aix/Marseille. We used a self-administered questionnaire to collect information on self-reported VC and reasons for vaccination and non-vaccination. We compared proportions, using the chi-squared test and prevalence ratios (PRs) with 95% confidence intervals (95% CIs). Results: of 1152 eligible residents, 703 (61%) participated in the study and 95 (14%; 95% CI: 12 17%) reported having had measles in the past. Of all participants, 613 (93%; 95% CI: 91 95%) reported having been vaccinated against measles and 389 (76%; 95% CI: 73 80%) received two doses. Only 268 (38%) reported having visited an occupational health physician. Vaccinated individuals were more likely to report easy access to vaccination as the main motivation for measles vaccination, compared with unvaccinated residents (435; 71% and 21; 45%; P < 0.001, respectively). Conclusions: VC among the medical residents of the University of Aix/Marseille was well below the recommended 95% coverage for two doses of measles vaccination. The majority of the study participants had not visited an occupational health doctor. Lack of easy access seems to represent major barriers to measles vaccination. We recommend that the student union, occupational health services and hospitals co-operate and address these problems in order to improve VC in this group.
