How Long Does Natural Immunity Last?

Carol atkinson explains it well, but she puts actual science in you something you won't get from the left. They're down playing natural immunity because they need to keep the hysteria going. If they tell you that potentially a third of america may have some form of natural immunity this virus, we don't know how long it lasts. We've only been dealing with this virus for about a year and a half. I don't do pseudo science like byden and you two. But we know that they have likely, strong possibility, they have some form of immunity that may be durable. How long? We don't know.
