Because bleeding may occur following IM administration, use with caution.
Compared with giving hepatitis A vaccine alone, when coadministered with immune globulin, lower antibody titers may be obtained; however, hepatitis A vaccine and immune globulin may be given concurrently using different syringes and different injection sites.
May result in inadequate response to immunization; therefore, additional administration of vaccine may be required.
Use separate injection sites and syringes when injecting concomitant vaccines.
