Bacillus Calmette Guerin (BCG) vaccination is essential in the control
of tuberculosis (TB) especially in countries like Kenya where TB is s
till a public health problem and BCG is given to all children at birth
as a matter of policy. The present survey was launched in 1986 to ass
ess both BCG vaccination coverage and to compare its findings with the
1979/81 BCG scar survey results. Using random cluster sampling proced
ures, all primary school children aged 6-13 years from schools in each
of 12 districts were included in the survey. A total of 46357 school
children were registered. Of these, 3642 (7.9%) were excluded from the
survey for a variety of reasons. Of the remaining 42715 (92.1%) child
ren, 26781 (62.7%) had BCG scars present. Overall there was a signific
ant upward trend of 15% in BCG vaccination coverage in the country. Ho
wever, in some districts the coverage was found to have fallen quite s
ignificantly.
