Abstract
In a seroepidemiological survey on immunity to polioviruses, carried out in Rome, neutralizing antibodies were titrated on 602 serum samples collected from individuals aged 6 mo.-88 yr. The geometric mean titers were 25.24, 25.92 and 18.12 for poliovirus types 1, 2 and 3, respectively. The number of seronegative results for each virus strain was very low (.ltoreq. 1.5%). The immune status of the study population is satisfactory. The distribution of antibody reactivity in different age groups was similar for poliovirus types 1 and 3, while for type 2 a significant difference in titers was found between adults and children.This publication has 3 references indexed in Scilit:
