When a person is infected with a germ — a coronavirus, for example — the person's immune system creates proteins called antibodies tailor-made for that specific germ. Armed with those antibodies, the immune system can recognize the enemy in case it shows up again and fight it off.
Donated plasma is infused into patients to give an immediate boost to their immune system. There is anecdotal evidence it works.
But convalescent plasma relies on the altruism of blood donors, and blood donations cannot meet the demands of a pandemic
Monoclonal antibodies are made in a laboratory, designed to mimic the natural antibodies found in the body.
"Monoclonals are a refinement" of the convalescent plasma process, Gronvall said, "mass producing it as a purified form."
Convalescent plasma contains all of a person's antibodies to a variety of pathogens, not just the coronavirus. But in the lab, scientists can pinpoint specific antibodies and then manufacture them en mass
