Childhood immunisation in Bungoma County, Kenya, from 2008 to 2011: need for improved uptake

Abstract

Uptake of immunisations in children aged 1–2 years in Bungoma County, Kenya, was determined as part of the 6-monthly Health and Demographic Surveillance Sys- tem surveys. A total of 2699 children were assessed be- tween 2008 and 2011. During this time period, full im- munisation declined significantly from 84% to 58%, and measles vaccine declined uptake from 89% to 60% (P  0.001). Each year there was a significant fall-off for the third doses of the oral polio and pentavalent vac- cines (P  0.001). These findings are of concern, as low immunisation coverage may lead to vaccine-prevent- able disease outbreaks. Further investigations into theinform health policy and planning at local and na- tional levels. Among others, data on childhood immu- nisation was collected at 6-monthly intervals from households. The aim of the present study was to use the Webuye HDSS to report on immunisation uptake in children aged 1–2 years in Bungoma County be- tween 2008 and 2011. reasons for declining immunisation trends are required.
