Abstract
Purpose: The COVID-19 epidemic led to significant morbidity and mortality globally, especially among the elderly. Because SARS-CoV-2 is a novel viral pathogen, there was a lack of preventative and treatment options. Availability of effective vaccines has been an important factor in determining the epidemic trajectory. Analyzing the effects of the vaccines in reducing mortality across age groups is important for guiding future public health responses. The objective of this study was to determine the association between age and COVID-19 mortality pre- and post-vaccination periods amongst Georgians.
Methods: This cross-sectional study used COVID-19 case numbers, COVID-19 deaths, age at time of death, and vaccination status from the Georgia Department of Public Health’s COVID-19 Status Report. The main outcomes were COVID-19 case mortality rates, and the main independent variables were COVID-19 vaccination period and age. Logistic regression was performed to determine the association between mortality rate and age group, and vaccination period. ANOVA test was done to determine if case mortality rates increased with age group, and how it changed in the pre- and post-vaccination periods.
Results: Case mortality rates differed significantly by age groups (p
Conclusion: The vaccines appear to have mortality protective effects among those aged 60 and older. There were no such mortality benefits comparing pre- and post-vaccination periods for groups younger than 60.
