If an infant younger than age 6 months receives immune globulin (IG) before travel to a hepatitis A endemic area, will he/she need HepA vaccine before another trip to a hepatitis A endemic area?

Possibly. Since IG protects against hepatitis A infection for only 1 to 2 months, depending on the dosage given, additional IG may be needed if the infant is not yet age 6 months. Once the child has reached six months of age, HepA vaccine should be given.
