Bill Gates is hopeful that eventually there will be an effective coronavirus vaccine, but “we may need a second-generation” vaccine, he said, which could take a while.
In the near term, treatments could “cut the death rate quite dramatically, which would be a very big deal,” he said.
Gates said antiviral drugs, monoclonal antibodies, and steroids are all promising treatments that could be ready to go much sooner than vaccines, possibly in just a matter of months.

Bill Gates isn’t expecting a highly-protective coronavirus vaccine to be ready any time soon.
“The very first vaccine won’t be like a lot of vaccines, where it’s a 100% transmission-blocking and 100% avoids the person who gets the vaccine getting sick,” the billionaire philanthropist told Insider.
Vaccine trials take months, they don’t have to create completely effective inoculations, and they won’t help protect people who are already sick.
That’s why Gates is more excited, in the immediate term, about coronavirus therapeutics.
“It’s much easier to test a therapeutic than it is a vaccine,” he said during a wide-ranging chat earlier this week.
His best guess is that there are three different types of therapeutic treatments that could be available for coronavirus patients, in just a “few months.”
It’s not quite a reason to herald the end of the pandemic, but it’s a start.
“It doesn’t let you go to sporting events, or hang out at the bars,” he said. “You gotta get herd immunity [through vaccination] before you really do that.”
But these treatments, if shown effective at helping people recover faster and better from the virus, could be a game changer for the mounting coronavirus death toll. Already, more than 150,000 people are dead from the coronavirus in the US. Several estimates suggest roughly 40% of those deaths are linked to nursing homes.
“These things where nursing homes get infected, and very high death rates, the therapeutics will make a big difference there,” he said.
Here’s a breakdown of the three kinds of treatments Gates is most excited about:
Antivirals (as the name suggests) aim to act against a virus. They do this by preventing the virus from multiplying and reproducing. (The antiviral Tamiflu, for example, can help make flu infections shorter and less severe, if taken early on.)
One antiviral drug being used right now to treat the coronavirus is Remdesivir, a broad-spectrum antiviral and once failed Ebola treatment. Studies suggest it helps shorten coronavirus recovery time in patients who are very ill. In the US, Remdesivir is currently only being recommended for emergency use in hospitals (it’s approved in Japan). It is delivered intravenously (through an IV).
Remdesivir-maker Gilead announced on July 10 that its early trial results suggest the drug may cut hospitalized patients’ risk of death by 62%, when compared with the standard of care, calling it “an important finding that requires confirmation.”
More research on the drug is being conducted on thousands more hospitalized coronavirus patients now, with …read more
