The bigger effect may be that a more recent infection provides more immunity than an older infection because neutralizing antibodies wane. And we DESPERATELY need to come up with better terms to talk about immunity than just having one word for it. It really is likely that conserved t-cell epitopes confer life-long immunity against severe disease and death no matter which variant you are infected with or vaccinated against. While there is clear statistical evidence of the virus attempting to evade Nabs there's no evidence that mutations are concentrated around t-cell epitopes (probably one effect and reason why we have multiple tiers of immunity rather than just pumping out NAbs every time?).
