CALLER: I've listened to you, I believe that we need to be working hard to develop new therapeutics, so I agree with you 100 percent --

MARK LEVIN (HOST): But I'm saying two, three days, then they have natural immunity and they actually have better immunity than people who are vaccinated. And we're not taking that into account.

You try, doctor, you go to the CDC website and tell me if you can find how many people are mentioned there, the numbers, the data on natural immunity, the antibodies. You're not going to find it. Why? I'm not a conspiracy nut, but why? Why do we treat -- how many of the unvaccinated are people who have natural immunity? It's got to be a significant percentage of them.

CALLER: No, you're right, so I'm excluding people who have already been -- contracted COVID and have natural immunity, but I'm talking about people who have not been contracting --

LEVIN: But here's another theory, or at least not theory, another model of thinking, and that is -- and DeSantis and others think this -- if people want to get vaccinated, they should.

If they don't, they come down with the virus. They get the natural immunity, they're treated with therapeutics, they go back into society. They're less of a threat than people who've been vaccinated.
