Pasteur

In May 1881, Louis Pasteur performed a public experiment to demonstrate his concept of vaccination. He prepared two lots of 25 sheep. The sheep of one lot were all injected with a self-prepared antianthrax vaccine twice, with an interval of 15 days. The sheep of the other lot were left alone. 30 days after the first injection, both lots were injected with a culture of living anthrax bacteria. Each one of the sheep in the non-vaccinated pen died shortly after, whilst all of the sheep in the vaccinated lot survived.
