Abstract

Objective: to analyze the relationship between the number of doses and manufacturers of COVID-19 vaccines and the impact on mortality in older people. Methods: this was an analytical ecological study of people aged 60 and over. The data were obtained from the official Vaccinometer and Coronavirus Dashboard websites and analyzed using descriptive statistics and a generalized linear model with a negative binomial distribution. Results: the COVID-19 mortality coefficient was 498.360/100,000 elderly people before vaccination began and 327.880/100,000 elderly people after vaccination began. Notably, the Janssen vaccine showed a 54.6% reduction in the risk of death in this population group. Conclusion: the analysis of the relationship between the number of doses and manufacturers of COVID-19 vaccines and the impact on mortality showed a positive result, with a significant reduction in the annual mortality rate of the disease among the elderly population after vaccination began. Contributions to practice: the study shows the importance of immunization against COVID-19 in the elderly, highlighting the importance of adherence to booster doses so that this population remains protected.
