Microsoft founder Bill Gates believes there could be some advances in testing and therapeutics in the next year.
"I think the therapeutics is actually the most promising thing and not talked about as much as the vaccines because if you have multiple therapeutics that, between them, are reducing the death rate and the amount of serious sickness by over 80%, probably over 90%, that does start to reduce the horrific burden," the philanthropist said.
"So I think by the end of the year, therapeutics will be making a big difference," he said.
Gates said by the first half of 2021, the first round of vaccines could be approved.
"Then by the end of 2021, if people are willing to take the vaccine, we'll be able to stop the transmission in the rich countries and maybe within nine months after that in the world at large," he said.
