To determine whether the change from the door-to-door strategy of administering the Oral Polio Vaccine (OPV) to designated vaccination points has led to less than optimal vaccination coverage.
The Second Bi Annual Poliomyelitis Vaccination ended on 28 Rajab 1417N (9 December 1996G). To minimize the high cost in terms of staff and financial resources, the local authority in the Eastern Province offered the vaccinations at various primary health and commercial centers, schools and private hospitals. The WHO cluster sampling technique was used to conduct a survey in the Al-Khobar and Qatif areas to verify the percentage coverage using the new strategy.
A total population of 1399 including 644 adults and 755 children (317 Al-Khobar, 438 Qatif) was surveyed. There were 153 children aged less than 5 years in Al-Khobar and 179 in Qatif Of these, 148 (96.7%) in Al-Khobar were vaccinated compared to 179 (100%) in Qatif. Only 5 of the eligible children were not vaccinated, two of whom were Saudis and three non-Saudis.
The study shows an overall percentage coverage of 98.4 in the Eastern Province which is well above the WHO's minimal 80% target for success. This method of vaccination at assigned points may be used in areas where the literacy rate is high and public cooperation is at a maximum.
