The title says it all:  antibodies that "may" eliminate the need for covid antibodies???
They knew from early on that monoclonal antibodies worked against the original covid virus. Even if efficacy was decreased with later variants, antibodies from patients recently recovered would work against the latest variants in the area.
There are also inexpensive medications that work against covid and its variants, to decrease length and severity of the illness, and almost eliminate hospitalization and death.
There was never any need for vaccines, which is why this information was suppressed. They wanted their share of the money from the companies making the vaccines.
