considering the rare occurrence of neurologic events after dtp vaccination , the generally benign outcome of febrile convulsions ( which make up the majority of these neurologic events ) , and the possible increased risk of pertussis in the general population if the estimated 5 % to 7 % of persons with a first-degree family history of convulsions were exempted from pertussis vaccination , we further conclude that a history of convulsions in siblings or parents should not be a contraindication to pertussis vaccination .
