Abstract

Hepatitis B is a serious infection caused by a virus from the Hepadnaviridae family. It is estimated that 57% of cases of liver cirrhosis and 78% of primary liver cancer are caused by hepatitis B or C viruses. This study investigates the demographic and epidemiological aspects associated with immunity to the hepatitis B virus in students from the health area. The research design was descriptive, prospective and cross-sectional, with an explanatory level. The study population selected by simple random sampling. Specific anti-surface antigen antibodies to hepatitis B virus were determined in serum samples by ELISA. Of the total analyzed, the highest immunity was in the female gender from 17 to 22 years old, of mixed race (94%); 20.82% of the students were seronegative. The results on the epidemiological aspects related to immunity in the study sample show the need to implement vaccination campaigns in health students and investigate factors associated with the lack of response to the vaccine in non-responders
