ABSTRACT
Neurologic complication associated with the use of live attenuated oral poliomyelitis vaccine is uncommon, but vaccine-associated paralytic poliomyelitis in recipients or contacts has sometimes been reported. We report here a community- acquired aseptic meningitis case and the genetic investigation of the isolated poliovirus type 2. The results of the genetic analysis indicate that the mechanism of this meningitis could be the result of the reversion of the virus during replication in the other vaccine recipients, suggesting a quest for revising the current vaccination program.
