ABSTRACT
The article focuses on a study which highlights natural infection in tuberculosis does not confer protective immunity yet only 10% of those that are infected progress to active disease. Indeed, recent human molecular epidemiological studies show that previous infection does not protect against re-infection progressing to active disease and, moreover, at the site of human disease there are high IFN-γ levels. The study raises the question of whether the strategy to identify vaccine candidates by using the IFN-γ response as a surrogate marker of protective immunity is a valid one.

    Background: The vaccine efficacy reported following Mycobacterium bovis Bacillus Calmette Guerin (BCG) administration to UK adolescents is 77% and defining the cellular immune response in this group can inform us as to the nature of effective immunity against tuberculosis. The aim of this study...

    Development of a vaccine with enhanced efficacy compared to that of the Bacillus Calmette Guerin (BCG) vaccine is essential to reduce the global TB burden. This is challenging since an effective vaccine will need to induce protection that surpasses that induced by natural infection with M....

    The tuberculin skin test (TST) and QuantiFERON-TB-Gold-In-tube (QFTGIT) are adjunctive tests used in the diagnosis of pediatric tuberculosis (TB). Neither test can rule out TB; however, a positive test usually triggers preventive treatment in TB contacts aged <5 years. TST and QFTGIT can give...

    Background: There is an urgent need of prognosis markers for tuberculosis (TB) to improve treatment strategies. The results of several studies show that the Interferon (IFN)-g-specific response to the TB antigens of the QuantiFERON TB Gold (QFT-IT antigens) decreases after successful TB therapy....
