There are 70 coronavirus vaccines in development globally, with three candidates already being tested in human trials, according to the World Health Organization, as drugmakers race to find a cure for the deadly pathogen.
The furthest along in the clinical process is an experimental vaccine developed by Hong Kong-listed CanSino Biologics Inc. and the Beijing Institute of Biotechnology, which is in phase 2. The other two being tested in humans are treatments developed separately by U.S. drugmakers Moderna Inc. and Inovio Pharmaceuticals Inc., according to a WHO document.
Drugmakers big and small have jumped in to try to develop a vaccine, which would be the most effective way to contain the virus. Pharmaceutical giants like Pfizer Inc. and Sanofi have vaccine candidates in the preclinical stages, according to the WHO document.
