Dr. Anthony Fauci said Thursday night on CNN that he didn’t have a “firm answer” as to why those who have been previously infected with Covid and have natural immunity are being required to take the vaccine.
Dr. Sanjay Gupta, CNN’s Chief Medical Correspondent, pointed out a recent study from Israel that found people with natural immunity from Covid due to a previous infection were much less likely to become infected, be hospitalized, or die from Covid than their counterparts who had never been infected but had received both doses of the Pfizer vaccine. The scientists also found that previously infected people were more protected if they had one dose of the Pfizer vaccine.
Gupta asked if previously infected people should also get the vaccine, and if so, how Fauci plans to make the case for those people to get it.
“You know, that’s a really good point, Sanjay. I don’t have a really firm answer for you on that,” Fauci said. “That’s something that we’re going to have to discuss regarding the durability of the response.”
Fauci also said that the study didn’t discuss how long the immunity lasts.
“The one thing the paper from Israel didn’t tell you is whether or not as high as the protection is with natural infection – what’s the durability compared to the durability of a vaccine? So it is conceivable that you got infected, you’re protected, but you may not be protected for an indefinite period of time,” he added. “So I think that is something that we need to sit down and discuss seriously, because you very appropriately pointed out it is an issue, and there could be an argument for saying what you said.”
