Jean-Marie Camille Guérin (1872-1961) was a French veterinarian and bacteriologist who joined Calmette at the Institut Pasteur in Lille in 1897. The two became celebrated for their anti-tuberculosis serum based on Guerin's demonstration that bovine Mycobacterium bovis exerts an immunological-protective effect in experimental rabbits. The result was their BCG (Bacillus-Calmette-Guérin) vaccine against tuberculosis, which has been improved continually over the following two decades and, indeed, to the present day.
