Final answer:
One other disease that now has a vaccine, as mentioned in the references, is polio, which has been nearly eradicated due to effective vaccination campaigns.
Step-by-step explanation:
One other disease mentioned in the provided references that now has a vaccine is polio. Like smallpox, polio was once a devastating viral disease causing paralysis and was often fatal.
With the introduction of the Salk and Sabin polio vaccines, the incidence of polio has dropped dramatically. As a result of worldwide vaccination campaigns, polio has been nearly eliminated globally and is now rarely seen in the United States.
This makes polio an excellent example of how vaccines can lead to the control and potential eradication of infectious diseases.
