Feb 23, 2017

Researchers are eager to test promising vaccines against Zika, the virus that sparked a global health emergency last year.

Ten thousand years ago, at the dawn of the agricultural revolution, many of our worst infectious diseases didn't exist.

When Ebola struck West Africa a few years ago, the world was defenseless. There was no cure. No vaccine. And the result was catastrophic: More than 11,000 people died. Nearly 30,000 were infected.

The world now has a potent weapon against Ebola: a vaccine that brings outbreaks to a screeching halt, scientists report Thursday in The Lancet.
