The goal of any immunization program is to achieve the highest protection degree against diseases preventable by immunization, with the lowest rates of adverse reactions; vaccination constituting a fundamental instrument of public health. The objective of this work was to characterize the adverse events supposedly attributed to vaccination in the Isle of Youth, Cuba, from January 2013 to October 2016. A descriptive, observational and cross-sectional study was carried out by passive surveillance. The epidemiological questionnaire was used as a primary source for gathering data in the 507 patients with adverse events. It was demonstrated that the years 2014 and 2015 surpassed the global rate for that period (34.6 per 10000 administered doses), while the health area “Leonilda Tamayo Matos” contributed the highest rate of events: 197 (39.7 per 10000 administered doses). The vaccines with most reports were: Pentavalente 280 (252.0 in 10000 administered doses), DPT 66 (168.4 per 10000 administered doses) and the meningococcal-BC 86 (92.6 per 10000 administered doses). The highest rate of adverse events was observed in the year 2014, with predominance in the health area “Leonilda Tamayo Matos”. The results obtained demonstrate the low rate of serious adverse events. The most common manifestations were fever and severe local reactions. The reliability of the system and the vaccine safety were once again reaffirmed
