Cholera Vaccine

 Louis Pasteur introduces a new vaccine.

 French chemist who work in the field of microbiology and chemistry led to a list of scientific discoveries. 

 Always remembered for his development of pasteurization in milk and invention of vaccines 

He introduced vaccine for rabies  and anthrax.

 Discovery for vaccination for cholera was just an accident 

In 1880, he was conducting experiments on chicken with cholera, and had instucted his assistant Charles Chamberland to inoculate the birds with a culture of cholera bacteria.

Chamberalnd failed to do correctly, a month later the spoiled culture used on birds became ill but didnt die

Pasteur realized that the weakened bacteria produced immunity

This allowed the vaccine to be created in large quantities which prevented disease.
