| Resumen | Objectives: The purpose of this study was to compare case fatality rates (CFRs) and odds for mortality by risk factors of patients with COVID-19 in Mexico, before, during and after the implementation of the national COVID-19 vaccination programme.Study design: A large database including COVID-19 monitoring cases was used to perform an observa-tional retrospective study.Methods: The Chi-squared test and multivariate logistic regression analyses were applied to data from COVID-19-positive patients in Mexico. Data were analysed over 3 years, 2020, 2021 and 2022, corre-sponding with pre-, during and post-vaccination periods. The unadjusted odds ratios and 95\% confidence interval were used to estimate the risk factors for COVID-19 mortality in each of the years. Results: Statistically significant differences in CFR and odds ratio were found in the studied years, favouring postvaccination period. Significant changes in CFR by age, sex and main comorbidities indi-cated changes in the epidemic dynamics after the implementation of the COVID-19 vaccination campaign. The likelihood of death increased for hospitalised cases and for patients who were middle-aged or older in 2021 and 2022, whereas the odds of death associated with sex and comorbidities remained similar or reduced over the 3 years.Conclusions: Implementation of the COVID-19 vaccination programme during 2021 showed positive consequences on CFR. The increased odds of dying in hospitalised patients are likely to be due to the unvaccinated proportion of patients.(c) 2022 The Royal Society for Public Health. Published by Elsevier Ltd.
