National Serosurvey of Post Vaccination Poliovirus Antibody in Saudi Arabia

This is a national seroprevalence study conducted in Saudi Arabia in 1991G to determine postvaccination poliovirus antibody. Two hundred and nine children vaccinated with three oral polio vaccines at three, four, and five months of age were included in the study representing the five main regions in Saudi Arabia. Blood samples were collected at the age of nine months. Cytopathic effect (CPE) neutralization was used to determine the level of polio antibody. A dilution of 1/8th or more was defined as positive. Seventy-nine percent, 88% and 65% of the children were positive for Type 1, Type 2, and Type 3, respectively. Development of a new strategy of polio vaccination is needed.Ann Saudi Med 1994;14(2):111-113.
