We know from over a century of immunizations that natural immunity is rarely better than acquired immunity via vaccination. This is the point of vaccines in the first place.
With covid we know that natural immunity decreases significantly after 6 months (but so does immunity provided by vaccination). We know the vaccine provides inconsistent immunity (we know people have been infected 3 times....so much for natural immunity).
One thing we do know is the vaccine is more effective against covid than natural immunity, superior against varients to date, and far safer than acquiring natural immunity.
The issue is science verses conspiracy. Anti-covid-vaxers are the flat-earthers insofar as virology is concerned. They reject science in favor of their "science (on this board they have rejected virologists, experts at the CDC, major medical universities, research facilities, the ANA, and the FDA in favor of surgical oncologists, psychiatrists, psychotherapists, dentists, and sales representatives).
