Does Prophylactic Vaccination Favour the Development of Poliomyelitis?

Abstract

Summary Seventy six cases of poliomyelitis have been admitted in St. Sophie Children's Hospital during the autumn of 1950. In seventeen of them there was a history of previous vaccination with mixed vaccine (pertussis‐tetanus‐diphtheria). The interval between vaccination and the appearance of paralysis was 2–14 days. In 75 % of the cases the paralysis occurred in the vaccinated limb.
