“If the body is capable of making an immune response to clear the virus in natural infection, that’s a pretty good proof of concept to say that you’re going to make an immune response in response to a vaccine,” Fauci stated.

But he added: “There’s never a guarantee, ever, that you’re going to get an effective vaccine.”

Lingering questions on immunity and vaccines

Researchers are nonetheless lacking two key items of details about immunity to the coronavirus: whether or not everyone who will get contaminated develops immunity, and the way lengthy that safety lasts.

“I have examples of people who were clearly infected, who are antibody-negative,” Fauci stated, including that these folks doubtless have antibody counts too low for the take a look at to detect. It’s unclear if such low antibody ranges are sufficient to guard somebody from reinfection. Other recovered sufferers, in the meantime, present excessive antibody counts.

“It isn’t a uniformly robust antibody response,” Fauci added.

That may imply {that a} vaccine may not produce excessive ranges of antibodies in some folks.

For those that do achieve immunity from a vaccine, it is also unclear how lengthy that safety would final. Other coronaviruses — the sort that trigger widespread chilly — produce immunity that lasts lower than a 12 months, and in some instances only a few months.

“It may be completely different with this coronavirus,” Fauci stated. “We don’t know.”
