This vaccine may be administered simultaneously with the measles-mumps-rubella vaccine or with any recombinant Hepatitis B surface antigen vaccines, but in two separate sites.
Interference with laboratory testing: Due to the urinary elimination of the Hib polysaccharide capsular antigen, a positive result may be observed in a urine test for 1 to 2 weeks after vaccination. Other tests should be done to confirm Hib infection during this time.
