Cows to the COVID-19 rescue? Maybe. Cattle are being used to develop a possible antibody treatment for coronavirus. Cows have human chromosomes, and SAb Biotherapeutics in South Dakota is hoping their blood could help make a drug to fight COVID-19.
Using genetic engineering, scientists create a cow embryo that contains parts of human chromosomes. That embryo becomes a calf and then a cow.
Then, a non-infectious part of the novel coronavirus is injected into that cow. Because of genetic engineering, the cow produces human antibodies to the virus.
Those antibodies are collected from the cow, and once purified, become a drug that might work to combat the coronavirus in humans So these cows are plasma donors just like humans who've recovered
