Abstract:
Haemophilus influenzae type b is the leading cause of meningitis in children younger than 5 years of age in the United States.1 The incidence of infection with H influenzae type b in certain populations, such as Apache and Navajo Indians and Alaskan Eskimos, is 10 to 20 times higher than in the general US population.2-4 Another important feature of H influenzae type b infections in these populations is that more than 80% of the cases occur during the first year of life, with 35% to 45% occurring during the first 6 months. One of the currently licensed vaccines that contains the capsular polysaccharide of the H influenzae type b organism is not reliably immunogenic in infants younger than 18 months of age.5,6 A number of new H influenzae type b vaccines prepared by covalently coupling the H influenzae type b capsular polysaccharide with a protein carrier antigen are undergoing clinical evaluation.7-13 One of these conjugate vaccines was shown to be efficacious in preventing disease caused by H influenzae type b in Finnish infants when they were immunized at 3, 4, and 6 months of age.14 Unfortunately, in a recently concluded trial, the same vaccine was not found to be efficacious in preventing such disease in infants younger than 1 year of age among the Alaskan Eskimo population.15 We have evaluated an alternative approach for protecting high-risk infants. A human hyperimmune globulin called bacterial polysaccharide immune globulin (BPIG) was prepared from the pooled plasma of adult blood donors immunized with H influenzae type b, pneumococcal, and meningococcal capsular polysaccharide.16
