As far as I know, all monoclonal antibody treatment for Covid is under Emergency Use Authorization only - they are experimental. RegenCov is an artificial "antibody cocktail" that tries to imitate real human antibodies. Like the vaxxines, we really don't know how these synthetic treatments behave in the long term. They do not know whether it is safe or effective to treat post exposure to SARS-CoV-2. The other treatment available is Sotrovimab which is derived from human immortalized cells lines - in other words, fetal tissue. Non synthetic monoclonal antibodies are derived from real tissue that come from either mouse cells or immortalized fetal cells - either kidney or lung.

So, your choice is another synthetic protein introduced into the body, or proteins derived from fetal tissue. They insist on pushing these expensive unproven drugs instead of early treatment. Ivermectin and HCQ along with appropriate supplements are by far the cheapest and most effective way to go - without all the side effects - add quercetin, hesperitin, bioavailable Curcumin, and NAC. The key is early treatment or don't get sick to begin with. Anyone that has previously had Covid already has antibody protection.
