Fauci says vaccines likely to offer only ‘finite’ protection

“We’re still knee-deep in the first wave” of the pandemic, Fauci said. Health officials are assuming a shot would offer a degree of protection, though it’s likely “going to be finite.”

A shot to protect against Covid-19 won’t work like the measles vaccine, which lasts throughout a person’s lifetime, Fauci said. “We may need a boost to continue the protection, but right now we don’t know how long it lasts.”

Fauci said he expects the American public will have an answer before the end of the year or by early 2021 as to whether one of the more than 140 experimental shots in development has proven safe and effective.

In the meantime, Fauci said public health measures such as wearing a mask, social distancing, and frequent hand-washing should be used as a vehicle to a safe re-opening. “It’s not an obstacle, it’s a pathway to do that. We can’t create this binary thing where it’s ‘us against them,’” he said.

NIH Director Francis Collins, who led the interview with Fauci, responded, saying: “Even this issue tends to get polarized, maybe even politicized. Imagine that!”
