摘要：A study was carried out in Delhi on the preimmunization status of infants aged 2-6 months with regard to poliomyelitis and on seroconversion after the administration of oral poliomyelitis vaccine. It was found that 30.3% of the 204 infants included in the study excreted enteroviruses, 58% of which were found to be polioviruses. Of 197 sera examined for neutralizing antibodies against different types of poliovirus, 73% were found to be triple negative and only 4.0% triple positive. Three doses of oral poliomyelitis vaccine were administered at intervals of 1 month. It was found that 71.8% of the vaccinated infants excreted cytopathogenic agents in the 7 days following the first dose; 80.4% of these agents were found to be polioviruses. Seroconversion was studied in 71 infants, and good antibody responses to all three types of poliovirus were observed. Full text Full text is available as a scanned copy of the original print version.
