Cross-sectional study on vaccination status and access barriers among displaced populations in Port Sudan camps (N=452); chi-square bivariate analysis, one-way ANOVA, and two binary logistic regression models identifying vaccination card possession, trust in services, and composite barrier burden as independent predictors of full vaccination. # Vaccination Status Among Children in Port Sudan Displacement Camps During Armed Conflict — 2025 **Study type:** Cross-sectional, community-based descriptive study **Degree level:** Clinical Master Degree in Family Medicine (Sudan Medical Specializations Board) **Institution:** Port Sudan, Red Sea State, Sudan **Sample size:** N = 452 caregivers and eligible individuals in displacement camps **Data analyst:** Abdulrahman Sirelkhatim --- ## Background The armed conflict that erupted in Sudan in April 2023 triggered one of the world's largest and fastest-growing displacement crises. By late 2024, an estimated 7.7 million people had been internally displaced, with Red Sea State — and Port Sudan specifically — emerging as one of the primary destinations for those fleeing conflict in Khartoum, Darfur, and Kordofan. Displacement camps around Port Sudan absorbed hundreds of thousands of individuals under conditions characterised by extreme overcrowding, limited sanitation, disrupted water supply, and severely constrained access to healthcare services. In this context, maintaining childhood vaccination coverage becomes both critically important and uniquely difficult. Vaccine-preventable diseases — including measles, polio, and meningococcal disease — thrive in displacement settings where population density is high, nutritional status is compromised, and herd immunity thresholds are difficult to sustain. The WHO and UNICEF have documented sharp declines in routine immunisation coverage across conflict-affected Sudanese states, with Red Sea State among those with the most concerning gaps. Yet no published study had characterised vaccination status, access barriers, and trust determinants specifically among the camp populations around Port Sudan during the current conflict. This study provides that baseline by documenting current vaccination coverage, identifying the structural and informational barriers that prevent full vaccination, and determining which sociodemogra …
