He said that almost 200 vaccine candidates are being developed to tackle the disease. “Almost 200 vaccine for Covid-19 are currently in clinical and preclinical testing. The history of vaccine development tells us some will fail and some will succeed,” Tedros added.
The WHO, in coordination with global vaccine alliance group Gavi and the Coalition for Epidemic Preparedness Innovations (CEPI), has created a mechanism to enable equal distribution of any Covid vaccines among countries in the future .
“The Covax facility enables governments to spread their reach of vaccine development and ensure their population can have early access to effective vaccines. Even more importantly, the Covax facility is the mechanism that will enable a globally coordinated roll out for the greatest possible impact,” the health organisation chief said.
