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.
