A new vaccine candidate against tuberculosis to replace BCG

Researchers at the Pasteur Institute have created a strain of Mycobacterium tuberculosis (TB bacteria) in the search for a new vaccine against tuberculosis. This strain of bacillus does not have certain characteristics which make it dangerous but is still capable of stimulating the immune system. Thus, in an animal model (mouse), vaccination with this strain slows the development of tuberculosis lesions. This work brings us closer to the discovery of a vaccine against tuberculosis, more effective than BCG.
