The calculus is different for tens of millions people who acquired natural immunity from previous infections before the vaccines even existed. I am one of them. There is no good reason for me to take the risk with the vaccines because it will only increase my immunity marginally.
I think the evidence available today contradicts this position. Vaccine immunity is much better than naturally acquired immunity, and natural immunity plus vaccine immunity is much better still.
I am sorry to say, but you’re mistaken. That might have been the case before the Delta variant but not anymore. Natural immunity is definitely better against the Delta variant.
