Abstract

Abancay is located at 2,395 m.a.s.l. in the Peruvian Andean Region. It is a hyperendemic area for Hepatitis B virus (HBV) and hepatitis delta virus (HDV) infection, where 7% of the deaths are caused by acute and chronic hepatitis infections. In 1991, a pilot immunization program against HBV infection was started to control the incidence of VHB-VHD, and as a strategy to improve the EPI coverage in general. Vaccination population was programmed to include 1,301 children under 1 year old and 3,488 children between 1-4 years old. A total of 3 doses of DNA recombinant vaccine against HBV per child were administered. The vaccination schedule fit within the EPI immunization schedule. For children under one year old, the program includes: Newborn: BCG, Polio 1, HBV1; 2-month old: Polio 2, DPT1, HBV2; 3-month old: DPT2, Polio 3; 4-month old: polio 4, HBV 3 and; 9 month old: Measles. For children aged between 1 and 4 years old, the program includes: HBV1, HBV2 one month after HBV1, and HBV six months after HBV1. One year after the immunization program started, 1,262 (97.0%) children under one year old and 2,529 (72.5%) between 1-4 years old were immunized. No relevant adverse effects have been reported. There were 8 deaths due to acute r...Continue Reading
