"Because I'm involved in developing these in the U.S. where all the patients are, there are a number of studies that are amazingly successful. We're talking close to 100%. In fact, we haven't seen a result yet under 100%. It looks like corona is very simple to kill,"  Professor Thomas Borody, medical director of Australia's Center for Digestive Disease. "It's available as a prescription medication. You wouldn't use it alone ... but you add two other things to it such as doxycycline and zinc."

Ivermectin is already approved by the FDA and is on the World Health Organization's list of model list of essential medicines.

"We had a 14-hospital trial in Bangladesh. We got [cured] 100 out of 100. In China, they tried to reproduce it. They got 60 out of 60 cured ... So I am behind the Ivermectin, doxycycline, zinc treatment because it has very few side effects and is a real killer of coronavirus," Borody said.
