What has Rudolf Weigl known for?

Rudolf Weigl invented Typhus vaccine. Typhus spreads through lice in the body and has been responsible for millions of deaths throughout history.

He discovered that a vaccine could be developed from lice stomachs infected with Rickettsia prowazeki, a harmful bacteria especially to humans. He developed this first version of the vaccine in 1918 and began experimenting on guinea pigs and even human volunteers. He refined this technique over the years until 1933, when he performed large-scale testing in order to cultivate bacteria and experiment with the lice using a micro-infection strategy.

Happy Birthday, Rudolf Weigl for saving thousands of human lives and earn their blessings.
