Abstract

The BCG vaccination has been employed as the main control measure for pulmonary tuberculosis in Korea since 1952. However, the protective efficacy of BCG against tuberculosis has been controversial worldwide. This study was conducted to evaluate the protective efficacy of BCG against pulmonary tuberculosis by a case-cotrol study. The study subjects included all the pulmonary tuberculous patients under 20 years of age who were registered in six health centers in Taegu City between May 1 and September 30, 1982. The controls were randomly selected among non-tuberculous out-patients matched by the age, sex and residence of the cases. The history of BCG vaccination was confirmed by the scar of 400 cases and 659 controls. The relative risk of the BCG recipients for pulmonary tuberculosis were 0.5 and the protective efficacy of the BCG was. 51.5%. It appears that the BCG vaccination is an efficient preventive measure in Korea where tuberculosis is prevalent. Thus the routine BCG vaccination should be continued.

1982년 5월 1일부터 9월 30일까지 5개월간 대구시내 중구 동구 서구 남구 북구 수성구 6개보건소에 등록되어 치료받고 있는 20세미만 폐결핵환자중 BCG접종 유무가 명확한 400명과 동 보건소에 참아온 일반환자 가운데 거주지역, 성 및 연령에 맞추어 뽑은 대조군 659명을 대상으로 BCG접종율을 기준삼아 BCG의 폐결핵 예방효과를 조사한 결과 그 성적을 요약하면 다음과 같다. BCG접종군이 비접종군보다 비교위험도가 2분의 1로 낮게 나타났으며, BCG접종으로 인한 예방효과는 51.5%였다. 따라서 BCG의 효과에 대한 많은 논란과 방해적으로 작용할요인, BCG접종으로 인한 합병증등 여러가지 문제들이 있으나 결핵유병율이 2.5%나되는 우리나라에서는 앞으로도 계속 BCG접종을 권장하여야 것 것으로 본다.
