[Juvenile myasthenia gravis of possible post-vaccinal inoculation: study of 2 cases].
The AA. describe two cases of serious juvenile myasthenia arisen after jennerian vaccination, antidiphteric and antitetanic vaccination in the first patient and after antitetanic vaccination in the second one. They put forward the hypothesis that in the two patients juvenile serious myasthenia is a complication due to vaccination for the following reasons: 1) the chronological relation between vaccination and the arising of myasthenic sumptomatology is very close; 2) the vaccine produces in the body a reaction of immunity type and myasthenia is nowadays generally considered as an immunity disease. Although the ways in which the vaccine inoculation can give rise to the disease are unknown, it can be supposed that in the occurrence at the same time of a genetic factor or of an susceptible area, the vaccine can act as a factor provoking the immunity answer of myasthenic type.
