Answer 1

The invention of the polio vaccine was the most important innovation because it saved countless lives by effectively eradicating a deadly disease that had previously caused widespread outbreaks and disability. The polio vaccine has been credited with significantly reducing the number of polio cases worldwide, with a 99% decrease in cases since the introduction of the vaccine in the 1950s and the near-elimination of wild poliovirus transmission in many countries.
