BCG vaccination excludes Crohn's disease relapse

Abstract

Background.

The incidence of nontuberculous mycobacterial (NTM) infections including Mycobacterium
avium subspecies paratuberculosis (MAP) infections is increasing worldwide. Should we rely on
the protective effect of BCG vaccination of humans against NTM too?

Methods.

The relationship between BCG vaccination and Crohn’s disease relapse has been re-analysed

Results.

The data of the study of Burnham et al. are to some extent biased. Nonetheless, the evidence
provided by the study of Burnham et al. cannot be ignored.
