ampaign has achieved its objectives. Setting: Various regions in the K
ingdom of Saudi Arabia (KSA) including Riyadh, Jeddah, Mekkah, Tabbouk
and Gizan. Material and methods: Randomized samples were obtained usi
ng the Bowleg's proportional allocation scheme. Housing blocks were se
lected using simple random sampling procedures. All Saudis and non-Sau

ire administered in a face-to-face interview by trained interviewers.
The data combined with those of an earlier pilot survey carried out in
Al-Khobar area were analyzed. Results: A total of 646 households were
surveyed; Riyadh 160, Jeddah 82, Mekkah 50, Tabbouk 164, Gizan 83 and
Al-Khobar 107. The under five population of children was 618. The cov
erage of the target population was Riyadh 88%, Jeddah 74%, Mekkah 93%,
Tabbouk 97%, Gizan 100% and Al-Khobar 100%. Conclusion: The overall p
ercentage coverage in the Kingdom was 92% which attests to the success
of the campaign. An area concern is Jeddah where the percentage cover
age was 74% and should receive more attention during the next national
vaccination campaign as well as mopping up vaccinations.
