Medical experts have found no such thing. The evidence suggests - and Dr. Fauci agrees - that there appears to be some short-term immunity. What is not known is how long it lasts.
“With this spike protein that’s being presented in the way that we do it with primes and in some cases boosts, we’re going to assume that there’s a degree of protection, but we have to assume that it’s going to be finite,” he added during a Q&A discussion with Dr. Francis Collins, director of the National Institutes of Health.
Fauci, the director of the National Institutes of Allergy and Infectious Diseases, added that reports of recovered Covid-19 patients being reinfected with the virus are probably inaccurate. He said it’s more likely that the test used to detect Covid-19 probably picked up fragments of the virus still in the recovered patient’s body, but they probably hadn’t been reinfected.
“There are no documented cases where people got better and actually got sick again in the sense of virus replicating,” he said. “I wouldn’t be surprised if there’s a rare case of an individual who went into remission and relapsed. ... But Francis, I can say with confidence, that it is very unlikely if it’s a common phenomenon.”
Dr. Fauci says coronavirus immunity may be 'finite,' duration remains uncertain
