Hepatitis A vaccines.
Hepatitis A, an acute usually self limiting infection of the liver is one of the most common vaccine-preventable infectious disease in the world. Effective vaccines which provide long term immunity against hepatitis A have been available since 1992. They are of known good quality, well tolerated with no serious adverse events and have been successfully used to protect different populations from infection as well as interrupt outbreak in closed communities. Mathematical models estimate the long term persistence of antiHAV antibodies to be more than 25 years. Vaccination efforts should be supplemented by health education and improved sanitation. Planning for large scale immunization programmes against hepatitis A should take into consideration epidemiological and cost benefit studies.
