Another important event related to vaccination occurred thanks to Louis Pasteur, a French chemist, and bacteriologist. He is considered the father of modern microbiology because of his countless contributions in this field. Pasteur created two vaccines for diseases caused by bacteria: the vaccine for chicken cholera in 1880 and the vaccine for anthrax in 1881. Later, in 1885, Pasteur creates the vaccine for rabies, also known as the rabies vaccine.
In this way, the experiments made by Jenner and Pasteur enabled the introduction of active vaccines. These vaccines were first developed with an attenuated vaccine method (known as first-generation vaccines); then, with the development of inactive microorganism vaccines; to continue with the polysaccharide vaccines and the genetic recombination mechanisms.
