The flu vaccine “isn’t that effective” in older people so vaccines for COVID-19 will have to be different, according to Bill Gates.
“Here we clearly need a vaccine that works in the upper age range because they’re most at risk of that.”
Vaccine researchers are working to try to create a vaccine that “works in older people” but doesn’t have any side effects, Gates added.
Researchers want to be cautious because they expect the vaccine to be injected into people across all age ranges, including pregnant women, undernourished individuals, and people with co-morbidities, or underlying health conditions, Gates told CNBC.
Understanding that projected widespread adoption, “it’s very, very hard, and that actual decision to say, ‘let’s go and give that vaccine to the entire world,’” Gates said. “Governments will have to be involved because there will be some risk and indemnification needed before that can be decided on.”
Gates, the founder of Microsoft and the nonprofit Bill & Melinda Gates Foundation, is funding seven different efforts to develop vaccines.
“Because our foundation has such deep expertise in infectious diseases, we’ve thought about the epidemic, we did fund some things to be more prepared, like a vaccine effort. Our early money can accelerate things,” he said during an appearance on “The Daily Show” on April 2.
“Even though we‘ll end up picking at most two of them, we’re going to fund factories for all seven, just so that we don’t waste time in serially saying, ’OK, which vaccine works?' and then building the factory.”
“The vaccine is critical, because, until you have that, things aren’t really going to be normal. They can open up to some degree, but the risk of a rebound will be there until we have very broad vaccination,” he said.
“We have to make sure that the vaccine is very low priced and that there’s a fund for buying it for everyone, whether you’re in a low-, middle-, or a high-income country,” she said.
Healthcare workers should get the vaccine first, followed by people in high-risk groups, such as people with underlying health conditions.
