SOME GOOD NEWS:

The 17-year effort to eradicate polio from the world appears to be back on track after nearly unraveling in the past three years.

A new strategy of using a vaccine targeting the dominant strain of the virus appears to have eliminated polio from Egypt, one of six countries where it was freely circulating. That approach is on the verge of doing the same in India. Twenty-five years ago, India had 200,000 cases of paralytic polio a year. A decade ago, it was still seeing 75,000 cases annually. Through November this year, it recorded 52.

This would be going better still if anti-vaccine hysteria hadn’t slowed things down.
