Although administration of hepatitis B immune globulin (human) did not interfere with measles vaccination, it is not known whether hepatitis B immune globulin (human) may interfere with other live virus vaccines. Therefore, use of such vaccines should be deferred until approximately 3 months after hepatitis B immune globulin (human) administration. Hepatitis B vaccine may be administered at the same time, but at a different injection site, without interfering with the immune response. No interactions with other products are known.
