Hepatitis A (HepA) vaccines

Routine vaccination:
  • Minimum age: 12 months
  • Inactivated HepA vaccine: Start the 2-dose HepA vaccine series for children aged 12 through 23 months; separate the 2 doses by 6 to 18 months.
  • Live attenuated H2-strain Hepatitis A vaccine: Single dose starting at 12 months and through 23 months of age
Catch-up vaccination:
  • Either of the two vaccines can be used in 'catch-up' schedule beyond 2 years of age
  • Administer 2 doses of inactivated vaccine at least 6 months apart to unvaccinated persons
  • Only single dose of live attenuated H2-strain vaccine
  • For catch up vaccination, pre vaccination screening for Hepatitis A antibody is recommended in children older than 10 years as at this age the estimated sero-positive rates exceed 50%.
