Abstract

Background: The rapid response of governments to overcome COVID-19 is increasingly important. In this study, we investigated the epidemiological changes of Covid-19 and the vaccination status of this disease in the Eastern Mediterranean Region (EMRO).
Methods: This research is a descriptive ecologic study. Data on vaccination status in the EMRO region were collected and Also the daily cases, daily COVID-19 mortality, the total number of deaths, and cases from January 3, 2020, to June 13, 2022.
Results: Iran had the highest number of known cases and deaths, while Bahrain and Tanzania had the highest cumulative rates of cases and deaths, respectively. The highest average monthly incidence rate changes were observed in Iraq, with 41.74%. Iran had the highest average monthly death rate changes with 25.75% and the highest number of known cases and deaths.The United Arab Emirates had the highest total vaccinations per 100 individuals and the highest percentage of persons fully vaccinated.
Conclusion: It appears that cooperation among countries in the region regarding vaccination can lead to a decline in the disease and ultimately control its spread. Furthermore, there is a noticeable decrease in the percentage of monthly changes after the start of vaccination in the EMRO countries. The gradual increase in some countries during the last segment highlights the importance of booster vaccinations.
