الملخص

Background: After achieving high vaccination coverage, vaccine failure may occur. Sufficient knowledge, practices, and safety practices of workers in the expanded immunization program are factors that affect the prevention of this failure.

Method: This quasi-experiment was conducted to assess the knowledge and practices of HCWs involved in the EPI, as well as their safety practices, before and after an educational intervention in Sa’adah, Yemen, in 2025. The study included 26 HCWs from 26 health facilities in 11 districts of the Sa’adah Governorate, Yemen. Data were collected through field visits to hospitals and health centers in the targeted districts between January 1 and January 20, 2025, to collect the data required for the pre-intervention knowledge, practice, and safety practice questionnaires. The second phase, four months after the intervention, from May 3 to May 13, 2025, collected post-intervention data. Data were analyzed using SPSS version 26.
Results: HCP knowledge scores improved after the educational intervention, from 26.9% ’good’ to 65.4%. HCP practices improved, with correct practices increasing from 76.9% to 92.3% (p = 0.015). Injection safety practices did not significantly improve. General secure safety practices increased from 26.9% to 92.3% for good practices after the intervention; the statistical significance was marginal (p=0.063).
Conclusion: Educational intervention programs in Sa’adah, Yemen, effectively improved healthcare providers’ immunization knowledge and practical skills.
