DTPa-HBV-IPV/Hib vaccine (Infanrix hexa)

Primary vaccination of infants with diphtheria-tetanus-acellular pertussis-hepatitis B recombinant (adsorbed)-inactivated poliomyelitis-adsorbed conjugated Haemophilus influenzae type b vaccine (DTPa-HBV-IPV/Hib; Infanrix hexa)-inactivated poliomyelitis-absorbed conjugated Haemophilus influenzae type b vaccine (DTPa-HBV-IPV/Hib) refers to Infanrix hexa trade mark.) provided high levels of seroprotection against diphtheria toxoid, tetanus toxoid, poliovirus 1, 2 and 3, pertussis antigens (pertussis toxoid, filamentous haemagglutinin and pertactin), hepatitis B virus surface antigen and H. influenzae polyribosyl-ribitol-phosphate (PRP) antigen. Most infants (97%) had anti-PRP levels >/=0.15 micro g/mL after a booster dose at 18 months. Primary vaccination with the DTPa-HBV-IPV/Hib vaccine produced a similar immune response to that with two different pentavalent plus monovalent vaccine combinations. Coadministration of DTPa-HBV-IPV/Hib vaccine and a heptavalent pneumonococcal conjugate vaccine resulted in a high level of seroprotection and was well tolerated. Primary or booster vaccination with DTPa- HBV-IPV/Hib vaccine was well tolerated. Commonly reported local adverse reactions included redness, pain and swelling. Systemic symptoms were usually mild to moderate, and included fussiness, fever, restlessness and sleepiness.
