Stanford is also remaining willfully ignorant of prior infection-conferred immunity, easily measured by IgG assay. This is all becoming very embarrassing.
Infection-conferred immunity is inferior to vaccine-conferred immunity.
Inferior in what way? There are several measures of effectiveness. When it comes to consistency of immune response, the vaccines are superior. When it comes to broad spectrum immunity to variants, infection-conferred immunity is superior. When it comes to how long immunity lasts, infection-conferred immunity is vastly superior.
That isn't so, and both controlled studies and population-level statistics make that clear.
