Vaccination emerged as the primary strategy for preventing the spread of the virus. This study aims to evaluate and analyze the COVID-19 vaccination status among the population of the Aïn Témouchent province. A descriptive epidemiological study was conducted from March 7 to April 13, 2025, on a representative sample of the local population. Data were analyzed based on vaccination status, gender, age group, type of vaccine administered, and reported side effects. The findings revealed a relatively low overall vaccination rate, with a higher proportion of vaccinated females (53.3%) compared to males (46.7%). The most represented age group among participants was 35 to 50 years (36.7%). The most commonly administered vaccine was Sinovac, accounting for 76.7% of vaccinations. The most frequently reported side effects were fever (34.8%) and fatigue (21.8%). Additionally, cases of post-vaccination infection were observed, raising concerns about the effectiveness of certain vaccines. This study highlights the need to strengthen vaccination coverage and continue evaluating post-vaccination immune responses in order to enhance the local fight against COVID-19.frCOVID-19, SARS-CoV-2, vaccine, pandemicThesis
