You realize the polio vaccine that saved so many lives would not be allowed to be given today because there was a slight chance that those receiving the vaccine would die?
Polio is coming back in this country because our borders are not secure. Which is more preventable?
—yes—
You know, prior to the vaccine, measles killed about 1 in 2,000 or even sometimes 1 in 2,500. For a better idea, the flu killed more during those times then measles, and it still kills thousands of people every year.
