name two scientists who discovered BCG.
Answers
Answer:
Albert Calmette
Albert CalmetteThe history of the BCG vaccine starts with Albert Calmette and Camille Guerin. They were two French scientists who from 1905 had been working on developing a vaccine against TB. BCG is an abbreviation of Bacillus Calmette-Guerin, meaning the bacilli of Calmette and Guerin.

They demonstrated that small doses of injected and weakened animal bacilli could be used as a protective vaccine against TB, in cattle and various species of monkey. So they then cultured the bacillus, and found that successive culturing weakened the bacillus.

The research had to stop during the first world war, but was resumed in 1918. By 1921 the tubercle bacillus had been sub cultured 230 times, and it was so weakened that it was believed that it could confer immunity without causing disease in humans.1 2

Answer:
The vaccine was developed over a period of 13 years, from 1908 to 1921, by French bacteriologists Albert Calmette and Camille Guérin, who named the product Bacillus Calmette-Guérin, or BCG.
