The Polio Threat Continues to Grow —But a New Vaccine Could Make a Difference

The recent return of polio has hit like something of an epidemiological thunderclap.

On July 21, however, the New York State Department of Health announced a case of polio in an unvaccinated man in Rockland County, and since then, circulating poliovirus has been found in wastewater there and in neighboring Orange County, as well as in New York City.

In 1988, polio was endemic in 125 countries and led to the death or paralysis of 350,000 people—mostly children—each year, according to the World Health Organization (WHO). But thanks to a massive vaccination push by the WHO, Rotary International, UNICEF, the U.S. Centers for Disease Control and Prevention (CDC), and more, polio is now endemic in just two countries—Afghanistan and Pakistan—which have seen only 18 cases between them so far this year. Polio, however, is creeping back, and health officials are now on the alert for what Paul Andino-Pavlovsky, a professor of microbiology and immunology at the Univers...
