It’s not sarcasm.
Covid has a very low mortality rate to begin with and would be far lower if treated early and effectively and politicians and medical personnel didn’t actively do stuff to kill people off.
Sorry. Misread your initial post.
You said “getting covid and recovering” and I totally misread it as “getting the covid vaccine”. That’s why I misinterpreted the remainder of the sentence where you mention “robust and long lasting immunity”.
I 100% concur. A naturally acquired immunity to Covid is definitely more adaptive and durable immunity.
