ProHIBiT (haemophilus b conjugate vaccine) ® is indicated for immunization against invasive diseases caused by Haemophilus influenzaetype b.^25,26 ProHIBiT (haemophilus b conjugate vaccine) ® may be administered as a booster vaccination at 12 to 15 months of age in children who received primary immunization with Haemophilus b Conjugate Vaccine (Meningococcal Protein Conjugate) or Haemophilus b Conjugate Vaccine (Diphtheria CRM₁₉₇ Protein Conjugate) as illustrated in Tables 2, 3, 4 and 5. This vaccine also may be administered as primary immunization at 15 months of age in children who have not received primary immunization with any licensed Haemophilus b Conjugate Vaccine.

Children With Symptomatic Human Immunodeficiency Virus (Hiv) Infection

Immunization with Haemophilus b Conjugate Vaccine is recommended by the American Academy of Pediatrics (Red Book) and Immunization Practices Advisory Committee (ACIP) for children who are immunosuppressed in association with AIDS or any other immunodeficiency disease.^26,27

ProHIBiT (haemophilus b conjugate vaccine) ® will not protect against Haemophilus influenzae other than type b or other microorganisms that cause meningitis or septic disease.

No impairment of the immune response to the individual antigens was demonstrated when ProHIBiT (haemophilus b conjugate vaccine) ® and Diphtheria and Tetanus Toxoids and Pertussis Vaccine Adsorbed (DTP) were given at the same time in separate syringes at different sites.^15,28

Limited data are available on concomitant administration of ProHIBiT (haemophilus b conjugate vaccine) ® with MMR, and OPV (IPV). Fourteen-month-old Finnish children boosted with PRP-D received MMR concomitantly. Pre and 4 weeks post sera from a small subset (11 patients), showed no significant difference in antibody response to Measles, Mumps, or Rubella antigens when compared to a group that received MMR alone. A group of 25 Finnish infants received concomitant DTP, PRP-D, and IPV was compared to a group of 25 receiving DTP and IPV only. No significant difference in response to Type 1, Type 2, or Type 3 polio antigens was noted. Response to oral Polio Vaccine was evaluated in 31 infants immunized with PRP-D who also received OPV concomitantly. No difference in response to Type 1, Type 2, or Type 3 antigens was observed when compared to 22 infants receiving placebo and OPV.^15,29

ProHIBiT (haemophilus b conjugate vaccine) ® IS NOT RECOMMENDED FOR USE IN CHILDREN YOUNGER THAN 12 MONTHS OF AGE.

Parenteral drug products should be inspected visually for extraneous particulate matter and/or discoloration prior to administration whenever solution and container permit. If these conditions exist, the vaccine should not be administered.

The immunizing dose is a single injection of 0.5 mL given intramuscularly in the outer aspect area of the vastus lateralis (mid-thigh) or deltoid.

Each 0.5 mL dose contains 25 µg of purified capsular polysaccharide and 18 µg of conjugated diphtheria toxoid protein.

Before injection, the skin over the site to be injected should be cleansed with a suitable germicide. After insertion of the needle, aspirate to ensure that the needle has not entered a blood vessel.

DO NOT INJECT INTRAVENOUSLY.

A booster dose of ProHIBiT (haemophilus b conjugate vaccine) ® should be administered to children 12 to 15 months of age previously immunized with any licensed Hib conjugate vaccine. A single dose of ProHIBiT (haemophilus b conjugate vaccine) ® should be administered to children 15 months of age and older, not previously immunized with a Hib conjugate vaccine.
