What did Pasteur develop?

He developed various vaccines and popularized vaccination.

Pasteur gave the name "vaccine" to Jenner's idea of a method to prevent smallpox, and thought that vaccines could be applied to other diseases as well.
Through his research, Pasteur succeeded in developing vaccines against rabies, chicken cholera, and anthrax.

He also introduced the concept of vaccination, in which the body is immunized in advance with a vaccine to protect against infectious diseases.

He also used his research to make vinegar and wine. In the course of his research, Pasteur was also involved in research that was useful to French food culture, such as developing a method for producing large quantities of vinegar through the action of microorganisms and a method for preventing wine from spoiling.

Why was Pasteur called the "father of bacteriology"?

While researching infectious diseases, Pasteur discovered that "infectious diseases are caused by bacteria.
He investigated various infectious diseases and succeeded in finding the bacteria that caused each one. By studying these bacteria, he developed vaccines to prevent various infectious diseases such as rabies.
Thus, Pasteur made great achievements in the study of bacteria, including the clarification of the relationship between infectious diseases and bacteria. For this reason, Pasteur is called the "father of bacteriology.

Did Pasteur also make vaccines for insects? A long time ago, a disease called "silkworm" was spreading in France, in which insects called silkworms were dying one after another. Silkworms produce silk thread from their bodies, which is the raw material for silk yarn. Silkworms produced silk thread, one of the main industries that supported France.
Pasteur discovered a bacterium that caused silkworm diseases and devised a method of prevention. It took five years of research, but he successfully saved an important French industry.

Is it true that people who were grateful to Pasteur gave him a laboratory?

His many research achievements, including vaccines against rabies, have saved many lives. France, the country where Pasteur was born, decided to donate the institute as a token of its gratitude. Donations came from all over the world, and in 1888, the Institut Pasteur was completed.
The institute continues to conduct research on microorganisms and infectious diseases.
It was at the Pasteur Institute that the AIDS virus (HIV) was discovered.
Pasteur's passion for research is still alive and well more than 120 years later.
