Abstract
Background: The global response to the COVID-19 pandemic has been characterized by unprecedented vaccination efforts aimed at mitigating the spread of the virus and curbing its impact on public health. Methods: This study presents a comprehensive analysis of the vaccination campaign in Tlemcen, Algeria, focusing on vaccine distribution, utilization, and demographic trends. Data from the Public Health Establishment near Tlemcen were analyzed using Excel and SPSS to assess the distribution and management of five distinct vaccine brands: Sputnik, AstraZeneca, Sinopharm, Sinovac, and Janssen. Statistical analysis included the calculation of means, standard deviations, and percentages to evaluate vaccine distribution, uptake, and wastage. Results: The findings revealed varying levels of efficiency and challenges in vaccine management across different brands. Specifically, Sinovac had the highest administered doses at 93,908, representing 91.94% of its total imported vaccines. Sputnik had the lowest wastage rate, with no expired vaccines and only 10.35% lost doses. Age-specific trends in vaccine uptake highlighted Sinovac's prominence among the 50-64 and 65+ age groups, while Janssen was more popular in the 30-49 age group. Additionally, individuals with comorbidities showed a higher vaccine response to Sinovac, suggesting the need for tailored vaccination strategies for this subgroup. Conclusion: These findings provide valuable insights into the dynamics of the vaccination campaign in Tlemcen and contribute to ongoing efforts to optimize vaccination strategies and mitigate the impact of COVID-19.
