The UW Population Health Initiative recently awarded CSDE Affiliate Michelle Shin (Child, Family, and Population Health Nursing) a Tier 2 pilot research grant to partner with a community health center and community-based organizations to increase vaccine uptake among children in East African communities in Washington State. East African communities, including Somali, Eritrean, and Ethiopian communities, face disproportionately high risk due to low rates of measles, mumps, rubella and varicella (MMRV) vaccination driven by misinformation and systemic barriers. Neighborcare, a community health clinic, and Shin have identified that East African patients under age two have 60–69% lower odds of receiving at least one MMRV vaccine dose compared to peers. To address this, Neighborcare, the Somali Health Board, and Shin propose a tripartite partnership to develop a community-informed intervention by conducting a community-engaged needs assessment and co-designing a culturally responsive vaccine communication intervention.
