SEGURA MORA, Mislai et al. Impact of anti-Sars Cov 2 immunogens on the number of confirmed cases of covid-19. Multimed [online]. 2023, vol.27  Epub 05-Sep-2023. ISSN 1028-4818.

Vaccination against SARS-CoV-2 has been established as a pandemic control measure, despite the continued emergence of new waves of cases. A retrospective correlational study of incident cases to Covid-19 was carried out to determine the association between vaccination with immunogens against SARS-CoV-2 and the incidence rate of confirmed cases. We used linear regression to analyze the relationship between variables, calculated effect size and statistical power with 95% confidence intervals. During 2021, 1,629 confirmed cases of COVID-19 were reported in Cauto Cristo, while 16,171 patients received the complete vaccination schedule (3 doses) with immunogens against SARS-CoV-2. The age group over 60 years had the highest percentage of confirmed cases (20.1%), with women being the most affected. The highest incidence rate was observed in family doctors' offices with the highest population density. The results of linear regression were statistically significant, with a value of F (1, 5) = 20.44 and p = 0.006. The coefficient of determination (R2) was 0.80, indicating adequate statistical power and effect size. The Durbin-Watson indicator was within the acceptable range (2.30), which allows generalizing the data obtained. The intervention with immunogens against SARS-CoV-2 in Cauto Cristo during the year 2021 was significantly associated with the reduction of the cumulative incidence rate of COVID-19. In addition, it was confirmed that age over 60 years is a factor associated with increased morbidity.
