by N.R. Saltmarsh, staff medical writer - A proposed cause-and-effect relationship between the measles-mumps-rubella (MMR) vaccine and the neurological disease, Guillain-Barre syndrome, now appears unlikely.
Researchers working in Finland reviewed hospital admissions data from a four-year period (1982-1986) to pinpoint MMR vaccine history among Guillain-Barre (GBS) patients.
Among the 189 patients hospitalized for GBS, 24 represented the target vaccine population and 20 actually had received the vaccine, noted A. Patja and colleagues at the University of Helsinki. None of the 20 patients, however, experienced onset of symptoms within the projected six-week time frame after MMR vaccination. Symptoms appeared anywhere from 80 days to years afterward.
Furthermore, patients who were vaccinated against MMR after recovery from GBS did not experience relapse ("Risk of Guillain-Barre syndrome after measles-mumps-rubella vaccination," Journal of Pediatrics, 2001;138(2):250-254).
