Immunoprophylaxis in tuberculosis.

In the Chingelput trial of immunoprophylaxis against tuberculosis, BCG vaccination did not protect against pulmonary especially bacillary tuberculosis commonly known 'adult form' of tuberculosis. The study however, did not answer the question whether BCG vaccination offers protection against 'childhood forms of tuberculosis' or not. However, notwithstanding these results, the study has generated some new ideas and has opened vast areas for future research. The results of new projects will be awaited keenly. The current situation is discussed here.
