This vaccine may be administered simultaneously, but at two separate sites with the M-M-RVaxPro vaccine or HBVaxPro vaccine.
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.
