Reb Eliezer,
“The CDC is ruling that people who had COVID should still get vaccinared as the antibodies are not that effective against the delta variant.”
Actually the opposite is becoming increasingly apparent – that immunity garnered from a Covid infection is more effective and longer lasting against the Delta variant than vaccine garnered immunity. It certainly doesn’t mean we should all run out and catch Covid, but why do none of these US-based mandates allow for T cell or antibody tests to demonstrate immunity?
