Protection provided by Haemophilus influenzae type b conjugate vaccines in Los Angeles County : a case-control study.
The objective was to assess the degree of disease control and to evaluate the protective efficacy of licensed Haemophilus influenzae type b (Hib) conjugate vaccines (HbOC, PRP-OMP, PRP-D) used routinely in children 2 to 35 months of age.
We conducted a case-control study in Los Angeles County between January 1,1991, and December 31,1992, and a cohort analysis of Hib cases between 1983 and 1992.
For the case-control study 105 cases of invasive Hib disease were identified and 767 geographically and age-matched controls were selected by random digit telephone dialing.
Sixteen HbOC vaccine failures occurred>14 days after a single dose of vaccine, 6 vaccine failures after 2 doses and 3 failures after 3 doses ; 2 cases occurred 6 and 12 days, respectively, after an initial dose of HbOC.
