ABSTRACT
Background: This study aims to compare mortality and adherence to the second dose between different types of vaccines administered in Palestine. Methods and Participants: A retrospective cohort study of individuals vaccinated against COVID-19 from February 14, 2021 through January 2022. Data were retrieved from the Palestinian Ministry of Health database and included identity number, date of birth, vaccination date, vaccine type, and mortality. Results: The study included 16,726 individuals who were vaccinated and later diagnosed with COVID-19. The mean age was 42.1 years, and females comprised 48.5% (8,112) of the population. Only 62.7% of individuals adhered to receiving the second dose of a vaccine, and the average duration of effectiveness of all vaccines was 126 days after completing the double dose. Seventy-five COVID-related deaths were recorded among vaccinated individuals who were significantly older ages. Conclusion: Our study design demonstrated the disparity in vaccine uptake and adherence due to delay in vaccination and dependence on COVAX and other countries for the donated vaccines. It highlights the importance of a global approach and higher-income countries assisting lower-income countries in securing vaccine.
