title: Haemophilus influenzae type b conjugate vaccine impact against purulent meningitis in Rwanda.
abstract: Rwanda introduced Haemophilus influenzae type b (Hib) conjugate vaccine in January 2002 and simultaneously implemented pediatric bacterial meningitis surveillance at a major referral hospital in the capital Kigali. We reviewed clinical and laboratory information collected during January 2002 to June 2006. Due to a variety of laboratory limitations, only eight confirmed Hib cases were identified, all before 2004. However, the proportion of cerebrospinal fluid with purulence decreased from 26.0% during 2002, to 15.9% during 2003, 9.7% during 2004 and 8.4% in 2005 (p<0.001). Vaccine effectiveness of two or three doses of Hib vaccine against purulent meningitis was 52% (95% confidence interval, 5-75%). In an African setting with few resources and in which few confirmed Hib meningitis cases were identified, Hib vaccine impact nevertheless could be demonstrated against the outcome of purulent meningitis and was found to be high.
