title: Who should receive hepatitis A vaccine?
abstract: Though a potent vaccine represents a powerful preventive tool, the policy of its use is governed by epidemiological and economical factors. Hepatitis A, an enterically transmitted disease shows distinct association with socio-economic status, populations with improvement experiencing lower exposure to the virus. With the availability of vaccine, it is pertinent to consider its use in the effective control of the disease. However, with the varied epidemiological patterns and economical constraints in different countries it does not seem to be possible to evolve universal policy for immunization. Though, universal immunization may be the most effective way of control, the same is not practical for many countries. It is proposed that irrespective of endemicity of hepatitis A, high-risk groups such as travelers to endemic areas, patients suffering from chronic liver diseases, HBV and HCV carriers, tribal communities with high HBV carrier rates, food handlers, sewage workers, recipients of blood products, troops, and children from day-care centers should be immunized with hepatitis A vaccine. In addition, for populations with intermediate prevalence, infants, children from affordable families may be immunized. As coupling the vaccine with EPI schedule would be beneficial, use of combined A & B or A, B & E vaccine may be an attractive alternative.
