International Medical Corps is a global, humanitarian, nonprofit organization dedicated to saving lives and relieving suffering through health care training and relief and development programs. Established in 1984 by volunteer doctors and nurses, International Medical Corps is a private, voluntary, nonpolitical, nonsectarian organization. Its mission is to improve the quality of life through health interventions and related activities that build local capacity in underserved communities worldwide. By offering training and health care to local populations and medical assistance to people at highest risk, and with the flexibility to respond rapidly to emergency situations, International Medical Corps rehabilitates devastated health care systems and helps bring them back to self-reliance This project aims to strengthen childhood immunization in Yemen, with a key focus on improving polio vaccination coverage through enhanced community awareness, social and behavioral change communication (SBCC), and active contact tracing. Given Yemen’s fragile health system and low routine immunization rates, the project targets high-risk and underserved communities where misinformation, vaccine hesitancy, and access barriers persist. Community health volunteers (CHVs) and outreach teams will be trained to deliver targeted SBCC interventions using culturally appropriate tools to build trust, dispel myths, and encourage timely vaccination. The project will also strengthen real-time contact tracing for missed children and suspected polio cases, linking them to nearby health facilities or mobile outreach units. Local leaders and influencers will be engaged to promote community acceptance and sustained behavior change. The combined strategy will close immunization gaps, improve community trust in vaccines, and contribute to preventing polio resurgence and other vaccine-preventable diseases in Yemen.
