Severe acute respiratory syndrome coronavirus 2 is the causative agent of COVID-19. In the week of March 21 to 27, 2021 an increase of 8% in cases was confirmed in Cuba. The Cuban Ministry of Public Health decided to approve the health intervention with the SOBERANA vaccine candidates to be administered to the staff working in health institutions. The objectives were to describe the vaccination coverage achieved with the SOBERANA heterologous scheme and the progression of the disease in the vaccinated subjects. This is a descriptive, prospective study. We perceived 884 subjects that fulfilled the criteria to be included. The subjects were followed up by the researchers of the sentinel site during the application of the scheme and 5 months after its conclusion. Adequate vaccination coverage was achieved for the heterologous scheme of three doses of SOBERANA. The most frequent comorbidities inside the group of workers who fell ill of COVID-19, 14 days after of completing the heterologous scheme were: high blood pressure, asthma, type 2 diabetes mellitus and ischemic heart disease. The bigger proportion of sick persons corresponded to those who worked in the high-risk red zone, followed by those who worked in the green zone and in the professional group, and lastly non-professional non-technical workers. Disease progression to severe and critical forms was not described in vaccinated workers. Symptoms and more frequent signs in the sick persons were fever, cough, asthenia and anorexia. Adequate vaccination coverage was achieved; the progression of the disease to severe or critical forms was aborted despite the high occupational exposure of the staff and chronic comorbidities.
