Rudolf Weigl: The Polish Biologist Who Developed Epidemic Typhus Vaccine

Vaccine for Epidemic Typhus: Rudolf Weigl, the Forefather

Famous as the man who created the first successful vaccine against epidemic typhus, Rudolf Weigl was a Polish biologist and inventor. His creative approaches to vaccine production opened the ground for future developments in the industry, and his scientific achievements will have a long-lasting impact on public health.

Beginnings in Life and Schooling

In the village of Koromysla, in what is now Ukraine, Rudolf Weigl was born on September 2, 1883, in Austria-Hungary. He was born into a musical household and went to a neighborhood school till he was a teenager. After graduating from high school, he continued his education at Lviv’s Jan Kazimierz University, majoring in natural sciences. Professor Stanisaw Pieniek, a famous biologist, instructed him in biology and entomology.

STEM Occupations

Weigl began working with Pieniek as his assistant at Lviv University’s Zoology Institute soon after he graduated. The Institute of Bacteriology and Serotherapy he founded in 1913 was dedicated to his ground-breaking studies on epidemic typhus. By infecting lice with a weakened strain of the bacteria that causes typhus, he devised a method for creating a vaccine against the disease. Lice infected with the disease were collected for use in making a vaccine.

The Impact on Public Health

The production process developed by Weigl for a vaccine against epidemic typhus was a major step forward in the battle against this disease, which had killed millions around the world. In the 1930s, his vaccination was used for the first time in Poland. It was subsequently adopted by other countries like Germany, Romania, and Japan. During World War II, Weigl’s facility in Lviv was a major producer of the vaccine, and his efforts directly resulted in the survival of countless people.

Results and Reputation

Our society is better off because of Weigl’s work in the medical and scientific fields. His work on the typhus epidemic was groundbreaking, and his methods for generating vaccinations continue to be used today. Weigl was well recognized as a leading scientific expert and the recipient of numerous prestigious prizes. He also had skills as an artist and musician, and he frequently included illustrations of his scientific findings in his works.


A leader in public health, Rudolf Weigl helped end the typhus epidemic that plagued Europe in the 19th century. His ground-breaking work in vaccine production paved the door for subsequent discoveries, and his legacy continues to motivate and encourage scientists and researchers today.


Exactly who was Rudolf Weigl?

Rudolf Weigl, a Polish biologist and inventor, created the first vaccination that successfully prevented epidemic typhus.

The term “epidemic typhus” does not ring a bell.

Fever, headache, and a rash are some of the symptoms of epidemic typhus, a highly contagious bacterial disease carried by lice.

The process by which Weigl created a vaccination against typhus.

To create a vaccination against typhus, Weigl infected lice with a virulent form of the bacteria responsible for the disease.

To what extent did Weigl help the public health system?

During World War Two, Weigl’s typhus vaccine prevented the spread of disease and saved many lives. His breakthrough approach to vaccine production also laid the path for future developments in public health.

Can you describe Weigl’s legacy?

Weigl’s contributions to medicine and science have improved the health of the general population, and his legacy has inspired many young minds to pursue careers in these fields.
