Neurologic complications of immunizations.
Although there does appear to be at least a temporal relationship between pertussis immunization and serious acute neurologic illness, data to suggest that children with stable preexisting neurologic disease or positive family history of neurologic disease are at increased risk for complications of pertussis immunizations are inconclusive. Furthermore, there are no firm statistical data concerning the incidence of pertussis vaccine-related encephalopathy. Rather, the literature on pertussis vaccine complications is replete with anecdotal reports and retrospective studies with a number of questionable conclusions drawn from this inadequate data base. Unfortunately, these conclusions have been sensationalized and exploited with litigious fervor to the point that the practice of pertussis immunization is being questioned in the United States. A number of points should be reiterated: pertussis is a dangerous and deadly disease, as seen in the epidemic in Great Britain; pertussis immunization is effective in protecting against the disease; and there is no conclusive proof that the incidence of complications from pertussis vaccination of children with seizure disorders or other preexisting stable neurologic abnormalities is higher, because appropriate studies have not been done to define such a risk. We would do well to keep these facts in mind in order to avoid a disaster similar to the pertussis epidemic in Great Britain. Pertussis vaccination should be given to all children except those with allergic hypersensitivity, a progressive neurologic disorder, or an adverse reaction to a previous pertussis dose.
