Evalution of the BCG Vaccination Programme. Part I: Late Consecutive Operational Assessment

ABSTRACT

The need for a BCG Vaccination Programme evaluation is explained and the methods generally applied in such evaluation namely- Concurrent, Early Consecutive and Late Consecutive Assessments are described. The paper covers the Late Consecutive Operational Assessment of the BCG Programme which took the form of a smallpox and BCG scar survey carried out on statistically representative rural and urban populations. An integrated and multi-purpose approach towards Smallpox and BCG Vaccination Programmes and an emphasis on the vaccination of children aged 0-9 years have been advocated with a view to achieving better coverage and greater epidemiological impact.
