“Because diphtheria and tetanus toxoids pertussis (DTP) vaccine is routinely given during the period of highest incidence of sudden infant death syndrome (SIDS), this study was undertaken to determine if there is a temporal association between DTP immunization and SIDS. Parents of 145 SIDS victims who died in Los Angeles County between January 1, 1979, and August 23, 1980, were contacted and interviewed regarding their child’s recent immunization history. Fifty-three had received a DTP immunization. Of these 53, 27 had received a DTP immunization within 28 days of death. Six SIDS deaths occurred within 24 hours and 17 occurred within 1 week of DTP immunization.”
