Pasteur

	Louis Pasteur was born in France in 1822. He was a scientist and he found out about bacteria. In 1885 a boy was bitten by a dog.  The dog was ill.  He had rabies.  Pasteur made a vaccine.
The boy was injected with the vaccine.  He did not become ill. Louis Pasteur also found that heat kills bacteria.  Today beer and milk are heated to make them safe.  This is called pasteurisation. Louis Pasteur died in 1895.
