A coronavirus vaccine will likely be multi-dose, Bill Gates says

Early data on a coronavirus vaccine shows that it will take more than one dose to protect people from the virus, Microsoft founder and philanthropist Bill Gates told CNN tonight.
Gates, who along with his wife Melinda, runs the Bill and Melinda Gates foundation which pledged up to $100 million in February to help contain the coronavirus outbreak around the world.
These funds have also been used to help find a vaccine for the virus, limit its spread and improve the detection and treatment of patients.
“None of the candidates that we have much data on look like they’ll work with a single dose. So these are all multi-dose vaccines. If we look at the elderly, some of the constructs might require more than two doses to get the protection we want,” Gates said during CNN’s town hall Thursday. “The vaccine has to be safe, it’s got to reduce transmission, and then it’s got to protect the health of the individual. And these vaccines, the FDA laid out how they want these trials to be done. Fortunately, they required a proof of efficacy. But they set the bar pretty low at 50% efficacy. So the first vaccine that gets approved may be fairly weak in some of these criteria.”
Gates said that his foundation is funding not only the first generation of vaccines and the capacity for those, “but also a second generation that will be ready four to six months later that may get us closer to 100% protection or 100% transmission reduction.”
“So there’s a lot of uncertainty in the vaccine enterprise, which is hard to explain, you know, when people want to summarize is the vaccine miracle on its way,” Gates added.
Here’s what the next year will look like, according to Bill Gates
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.
