The Norwegian meningococcal serogroup B outer membrane vesicle vaccine protection trials: case tracing, meningococcal antigen detection and serological diagnosis.
A survey is given of the efforts made to inform the general public, the potential vaccinees and their parents, and the health care personnel about meningococcal disease in general and the vaccination trial in particular, as a preparation for the meningococcal outer membrane vesicle serogroup B vaccine (MenB-vaccine "Folkehelsa") trials in secondary school students and military conscripts in Norway. Our case reporting system, supplementing the official notification, concerning even vaguely suspected cases in the age cohorts involved, is described. The efforts made to collect clinical material as well as laboratory and clinical data from 221 registered suspected cases are delineated. We also briefly summarize our cerebrospinal fluid antigen detection methods and diagnostic meningococcal serology work on these suspected cases. The compiled information on findings done at the admitting hospital of the possible cases and the additional diagnostic data provided at the National Institute of Public Health were put at the disposal of the independent Diagnosis Review Committee (DRC) as a basis for their diagnostic decisions before code opening for the meningococcal serogroup B outer membrane vesicle vaccine protection trial 3 June 1991.
