Louis Pasteur developed a vaccine for Rabies hence, the second statement is true.
However, Pasteur's rabies vaccine represented the first effective post-exposure treatment for people bitten by rabid animals, and Jenner's smallpox vaccine resulted in the eradication of smallpox.

Despite the existence of a relatively powerful vaccine, efforts to completely eradicate rabies are impractical because, unlike smallpox and polio, rabies may infect both domesticated and wild mammalian species.
