Eight children died, and the remainder had mental regression and retardation, chronic seizures, motor and sensory deficits, and movement disorders. The onset of neurologic signs or symptoms occurred with a nonrandom, statistically significant distribution of cases on days 8 and 9. No cases were identified after the administration of monovalent mumps or rubella vaccine.<\/jats:p><jats:p>Conclusions.\u2003This clustering suggests that a causal relationship between measles vaccine and encephalopathy may exist as a rare complication of measles immunization.<\/jats:p>","DOI":"10.1542\/peds.101.3.383","type":"journal-article","created":{"date-parts":[[2004,8,13]],"date-time":"2004-08-13T23:44:32Z","timestamp":1092440672000},"page":"383-387","source":"Crossref","is-referenced-by-count":52,"title":["Acute Encephalopathy Followed by Permanent Brain Injury or Death Associated With Further Attenuated Measles Vaccines: A Review of Claims Submitted to the National Vaccine Injury Compensation Program"],"prefix":"10.1542","volume":"101","author":[{"given":"Robert E.","family":"Weibel","sequence":"first","affiliation":[{"name":"From the Division of Vaccine Injury Compensation, National Vaccine Injury Compensation Program, Health Resources and Services Administration, Public Health Service, Rockville, Maryland;
