B.C.G. vaccination is offered to contacts of cases of tuberculosis, to medical and
nursing staffs of tuberculosis wards, and since 1957, as a result of the findings of the Medical
Research Council in their Tuberculosis Vaccines Clinical Trial, to children aged 13 and
over in Southall schools. Testing with tuberculin is carried out beforehand. The tuberculin
test, if positive, shows that infection has occurred at some time during life, and further
investigation is undertaken to verify whether this is active, chronic or healed infection, as
these all give the same result to the test. When the tuberculin test is negative and in the
absence of disease, B.C.G. inoculations are carried out in order to render the individuals
tuberculin positive and, therefore, to have immunity to infection by the tuberculous
bacillus.
Details of work on Southall contacts during 1963 and 1964 at Uxbridge Chest Clinic are as follows:—
