1. proved that germs cause disease
2. developed vaccines for diseases (rabies)
3. invented the process of pasteurization
the method by which bacteria reproduce and multiply- one cell divides and becomes two

prevents disease by injecting part of a pathogen (or instructions to make a part, mRNA) into a person so that the immune system learns to fight it off

capsule
