[Vaccine-related paralytic poliomyelitis with severe pareses. Report of one case (author's transl)].

In 11-year-old girl paralytic poliomyelitis developed 18 days after administration of trivalent oral poliomyelitis virus-vaccine. In spite of isolation and identification of vaccine-poliomyelitis-virus type III, there was only a slight raise of antibodies in the neutralisation-tests. The possibilities of lacking titer-raising is discussed, especially concerning the question of the claim to maintenance.
