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. ⋯ 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.
