Hepatitis B en Haitian Immigrants in Chile: Molecular Characterization and Determination of Vaccine Response

Summary

International migration to Chile has sharply increased since 2010. Particularly, Haitian migration now totals approximately 200.000 people. Preliminary results show a high prevalence of hepatitis B infection in this population. Approximately 35% of adult Haitian migrants in Chile have been exposed to hepatitis B infection. In this study the investigators aim to study the clinical and molecular characteristics of this infection and also to assess the serological response to an accelerated schedule of hepatitis B vaccination (0, 1 and 2 months).
