Complications of Pe Rtussis Immunization Neurological Complications of Pertussis Immunization

Since Madsen (1933) first drew attention to the possibility of serious consequences following active immunization against whooping-cough, reports of neurological sequelae of such immunization have come from various parts of the world. These sequelae (post-inoculation poliQmyelitis is not being considered here) have ranged from transient convulsions with complete recovery to gross crippling, mental retardation, and death. A survey of the literature, greatly facilitated by Kong's (1953) review of cases reported up to 1951, revealed records of 107 cases. A further case is now reported (the seventh from Great Britain), together with a review of the literature.
