Background: Measles is a highly contagious viral disease with serious complications. Currently, in Italy, measles vaccination is not mandatory for health care workers (HCWs) and medical students, and the free offer of the Measles Mumps Rubella (MMR) vaccine is the only national prevention measure to increase the coverage rate among these subjects. Aims: The aim of our study was to evaluate the impact on vaccination rate of the National Plan of Vaccine Prevention (NPVP) implemented in 2017. Material and Methods: This is a retrospective observational study that evaluated the measles-specific IgG immunity status of medical students at the University Tor Vergata of Rome, which underwent occupational health surveillance from 1 January to 31 December 2018. Results: In 2018, 84 of 319 students (26.30%) were serologically non-immune to measles; among these, 16 (19%) had previously been vaccinated, and 35 of the remaining 68 students accepted the MMR vaccine. Therefore, 33 out of 319 students did not undergo vaccination in 2018. These data are similar to those obtained in the previous year. In the 2017 screening, 84/314 (26.75%) students tested negative at the serological screening, whereas 15/85 (17.8%) among them documented a previous vaccination with two doses of the MMR vaccine; 69 students tested as unprotected. Vaccine compliance was 51.44%. Conclusions: No change in vaccination coverage occurred after the introduction of the last NPVP. Further efforts are needed to sensitize target populations about the relevance of vaccination; providing pre-employment screening for measles and free vaccine might be useful for this purpose.
