Abstract:
|
BACKGROUND: Over the past four decades, the World Health
Organization established the Expanded Programme on Immunization
(EPI) to foster universal access to all relevant vaccines for
all children at risk. The success of this program has been
undeniable, but requires periodic monitoring to ensure that
coverage rates remain high. The aim of this study was to measure
the BCG vaccination coverage in Manhica district, a high TB
burden rural area of Southern Mozambique and to investigate
factors that may be associated with BCG vaccination. METHODS: We
used data from the Health and Demographic Surveillance System
(HDSS) run by the Manhica Health Research Centre (CISM) in the
district of Manhica. A questionnaire was added in the annual
HDSS round visits to retrospectively collect the vaccination
history of children under the age of 3 years. Vaccinations are
registered in the National Health Cards which are universally
distributed at birth. This information was collected for
children born from 2011 to 2014. Data on whether a child was
vaccinated for BCG were collected from these National Health
Cards and/or BCG scar assessment. RESULTS: A total of 10,875
number of children were eligible for the study and 7903
presented the health card. BCG coverage was 97.4% for children
holding a health card. A BCG-compatible scar was observed in
99.0% of all children and in 99.6% of children with recorded BCG
in the card. A total of 93.4% of children had been vaccinated
with BCG within their first 28 days of life. None of the factors
analysed were found to be associated with lack of BCG
vaccination except for living in the municipality of Maluana
compared to living in the municipality of Manhica; (OR = 1.89,
95% CI: 1.18-3.00). Coverage for other EPI vaccines during the
first year of life was similarly high, but decreased for
subsequent doses. CONCLUSIONS: BCG coverage is high and timely
administered. Almost all vaccinated infants develop scar, which
is a useful proxy for monitoring BCG vaccine implementation. |
