• Hepatitis A
  • Administering Vaccines

To complete a 21-year-old patient’s HepA vaccine series, how many adult doses should I give if the patient received a single dose of pediatric HepA vaccine 5 years ago?

A person should receive the dosage of HepA vaccine appropriate for their age at the time of administration. You should give the patient one adult dose of HepA to complete the 2-dose series. It is not necessary to restart the vaccine series.
