Abstract

VALENZUELA B, M Teresa. Vaccines against hepatitis A and B in Chile. Rev. méd. Chile [online]. 2009, vol.137, n.6, pp.844-851. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872009000600017.

The mode of transmission and epidemiological approach for hepatitis A and B are different. However, both are preventable with vaccines whose efficacy and long lasting protection has been demonstrated. This review describes the secular tendency of both infections in Chile, their risk factors that have contributed to their persistence in the country and the interventions that have been carried out to reduce the disease burden. Although the vaccine for hepatitis B was incorporated to the immunization program in 2005, the vaccine for hepatitis A persists in the list of interventions that must be assumed with priority by the Ministry of Health. If Chilean health authorities pretend to reach the enteric disease indicators of developed countries, they must accelerate the epidemiological transition towards the elimination of hepatitis A.

Keywords : Hepatitis A; Hepatitis B; Viral vaccines.
