What vaccine was introduced as a result of Pasteur's work in the 1880s?

The rabies vaccine is the correct answer because it was developed by Louis Pasteur in the 1880s as a result of his groundbreaking research in microbiology and immunology. Pasteur's work demonstrated that by attenuating or weakening the virus that causes rabies, he could create a vaccine that would stimulate an immune response without causing the disease itself. This was a significant achievement in the field of vaccination, showcasing the principle of using a weakened pathogen to prevent illness.

In contrast, the smallpox vaccine was already established prior to Pasteur's time, developed by Edward Jenner in the late 18th century. The polio vaccine was created much later, in the 20th century by Jonas Salk and Albert Sabin, and the typhoid vaccine was also developed around the early 20th century by other researchers. Therefore, these options do not pertain to Pasteur's work and innovations in the 1880s specifically related to rabies.
