Objectives: To determine whether the addition of hepatitis B virus (HBV) vaccine to national immunization programs improved vaccination rates among refugee children, a marginalized population with limited access to care., Methods: The sample included 2291 refugees younger than 19 years who completed HBV screening after arrival in the United States. Children were categorized by having been born before or after the addition of the 3-dose HBV vaccine to their birth country's national immunization program. The outcome was serological evidence of immunization., Results: The odds of serological evidence of HBV immunization were higher for children born after the addition of HBV vaccine to their birth country's national immunization program (adjusted odds ratio = 2.54; 95% confidence interval = 2.04, 3.15)., Conclusions: National HBV vaccination programs have contributed to the increase in HBV vaccination coverage observed among US-bound refugee children., Public Health Implications: Ongoing public health surveillance is needed to ensure that vaccine rates are sustained among diverse, conflict-affected, displaced populations.

Objectives: We conducted a large-scale study of newly arrived refugee children in the United States with data from 2006 to 2012 domestic medical examinations in 4 sites: Colorado; Minnesota; Philadelphia, Pennsylvania; and Washington State., Methods: Blood lead level, anemia, hepatitis B virus (HBV) infection, tuberculosis infection or disease, and Strongyloides seropositivity data were available for 8148 refugee children (aged < 19 years) from Bhutan, Burma, Democratic Republic of Congo, Ethiopia, Iraq, and Somalia., Results: We identified distinct health profiles for each country of origin, as well as for Burmese children who arrived in the United States from Thailand compared with Burmese children who arrived from Malaysia. Hepatitis B was more prevalent among male children than female children and among children aged 5 years and older. The odds of HBV, tuberculosis, and Strongyloides decreased over the study period., Conclusions: Medical screening remains an important part of health care for newly arrived refugee children in the United States, and disease risk varies by population.
