Covid-19 probably can be eradicated globally, just like polio, according to research just published in BMJ Global Health. That assumes, however, that a high rate of vaccination occurs globally and that there is a quick response to emerging variants.

According to the Pharmaceutical Research and Manufacturers of America (PhRMA), there are 264 vaccines in development to prevent and treat diseases.

The spread of polio must still be classified as a public health emergency because, while progress has been made towards wiping out the disease, that progress is fragile, the World Health Organization (WHO) said.
