Abstract

Apache Indian infants have a high frequency of Haemophilus influenzae type b (Hib) and pneumococcal infections. Forty percent of Hib infections in these infants occur before the age of six months, when active immunization may not be protective. To evaluate the efficacy of passive immunization with a human hyperimmune globulin (bacterial polysaccharide immune globulin [BPIG]) prepared from the plasma of immunized adult donors, we randomly assigned 703 infants in a double-blind fashion to receive 0.5 ml of BPIG per kilogram of body weight (n = 353) or 0.5 ml of saline (n = 350) intramuscularly at 2, 6, and 10 months of age. Hib-antibody levels were significantly higher in BPIG recipients than in placebo recipients at 4, 6, and 10 months of age (P<0.001). During the first 90 days after BPIG or, HAEMOPHILUS influenzae type b (Hib) is an important cause of serious infections in infants and children.1 2 3 In the United States the highest attack rates of meningitis and other bacteremic infections due to Hib have been documented among certain American Indian and Alaskan Eskimo populations.4,5 In these high-risk groups, the majority of invasive Hib infections have occurred in children under one year of age, with up to 40 percent of cases occurring before six months of age.4,5 Therefore, prevention of Hib infections in young infants is a high priority for these populations. The currently licensed Hib vaccine consists of the purified…
