Title: Impact of Immunization on Polio Incidence in Sudan
Author: Hiba Thabit Hassan, Thabit
Abstract: The main aim of the study is to evaluate the relationship between the immunization and polio incidences in Sudan. By characterizing the relation between the percentage of immunization and number of incidence. Also to determine the effect of unvaccinated and uncompleted of immunization in describing the incidence. In this study secondary data covering the period from (1976- 2007) was used. The data was collected from annual reports of Federal Ministry of Health, the expanded programme of immunization and World Health Organization database. The study followed simple linear regression between the percentage of immunization at each year as an independent variable and number of incidence for the same year as a dependent variable. Also the study tested the multiple regression relationship between the numbers of children under five years old unvaccinated& uncompleted the three doses of vaccine and the incidences. The results showed that the mean of percentages of full immunization is 50.07; the mean polio incidence is 55.70 and a significance linear correlation between polio incidence and percentage of immunization, only 26% of the variation in incidence was explained by the percentage of immunization. The effect of the unvaccinated & uncompleted vaccination in the polio incidence is not significant.
