title: Effectiveness of BCG vaccination in Great Britain in 1978. A report from the Research Committee of the British Thoracic Association.
abstract: BCG vaccination of older school-children in Britain continues to offer more than 70% protection against tuberculosis for at least ten years after vaccination. In England and Wales between 1973 and 1978 the tuberculosis notification rate in tuberculin-negative unvaccinated life-time residents aged 15-19 years fell by 50%. There was no change in rate for those given BCG vaccination, possibly because of less satisfactory techniques of vaccination in some areas. It is estimated that for life-time residents of England and Wales BCG vaccination of 100 000 older school-children in 1978 will prevent about 44 notifications in the 15 years following vaccination.
