Introduction:

The Health Surveillance System reported in December 2019 cases with pneumonia in the city of Wuhan, China. The new disease, caused by SARS-CoV-2, was named COVID-19. On March 11, 2020, the first three imported cases were diagnosed in Cuba. The gradual introduction of different viral variants caused several outbreaks. It became necessary to look for alternatives that would allow epidemiological control to be achieved.

Objective:

Develop an effective health intervention with vaccine candidates aimed at reversing the epidemiological situation caused by the COVID-19 epidemic in Cuba during the period from January to August 2021.

Methods:

A qualitative action research study was carried out in three stages, with the application of debate groups that provided information for the organization of the process and decision making. In addition, it was based on the longitudinal descriptive study for the analysis of epidemiological data from the time series, which allowed to assess the effectiveness of the intervention. The study period spanned from January to August 2021.

Results:

The situational health study showed the level of complexity of the epidemiological situation and the prevailing social and economic context. Based on its results, the intervention project was designed and implemented, with the required feasibility conditions. The implementation of the intervention yielded favorable results, managing to vaccinate 99.16% of the planned population, with the consequent reduction in the incidence of cases by reaching vaccine coverage of 63.2%, 36% and 50.9% in the provinces of Havana, Matanzas and Santiago de Cuba, respectively.

Conclusions:

The health intervention, of a temporary nature, carried out with the vaccine candidates Soberana 02 and Abdala outlined a mode of action that extended beyond the intervention itself, by providing cultural, managerial, methodological, educational solutions, training in good practices, intersectorality, social participation and leadership management, which represent products extended to health services.
