Except it was widely reported that natural immunity lasted 3 to 6 months and that the vaccines would last 2 years (at least Moderna), and the nuances there I think would be lost on a lay person. I even had an immunologist explain to me in detail why the immunity from the vaccine would be way stronger than acquired immunity. It doesn't really build confidence in science if, while we're finding new things, everyone pretends that the conclusion du jour was always obvious.
