Hepatitis a vaccines

Abstract

Hepatitis A disease is increasingly being seen in older age groups in India, as the country becomes a region with intermediate endemicity for Hepatitis A infection. Prevention of Hepatitis A through immunization of children is the most effective strategy for control and prevention of the disease. Inactivated and live attenuated hepatitis A vaccines with excellent immunogenicity are available. Inactivated hepatitis A vaccines are recommended to be given intramuscularly at 12-23 months age in a two-dose schedule, 6-18 months apart. Live attenuated hepatitis A vaccine is recommended subcutaneously in a single dose schedule between 12-23 months of age.
