I made no mention of Sweden and have no idea what that has to do with natural immunity given their vaccination rate is 75% and their death rate is comparable to Germany and France. [0] [1]

> And note that it's not that good in the first place--plenty of reinfections because the immune system locked onto a part of the virus that changed.

You've got it exactly backwards. The vaccine uses only a part of the S-protein, whereas a natural infection exposes the body to the full S-protein and N-protein. In theory and in practice, the immune system can train on more viral features via natural infection than it can via vaccine.

> The vaccine has enough problem with immune escape, natural "immunity" fares even worse.

It really doesn't. [2] [3] [4] [5] [6]

> We present a systematic review and pooled analysis of clinical studies to date that (1) specifically compare the protection of natural immunity in the COVID-recovered versus the efficacy of complete vaccination in the COVID-naive ... it supports the pooled findings in finding superiority of natural immunity over-vaccination ... Consequently, no study could conclude the superiority of vaccination protection over natural immunity with statistical confidence, but observational studies endorsed an advantage for protection by natural immunity.
