A group of researchers from Brazil recently discovered antibody fragments produced in horses may be a way to fight COVID-19.
The researchers vaccinated horses against COVID-19 using recombinant trimeric spike (S) glycoprotein that created a serum made of purified antibody fragments.
After creating the horse vaccine, they tested hamsters.
Weight loss was used to measure improved conditions and the study shows the serum greatly reduced viral load as well as stopped the animals from losing weight. Animals that did not get the vaccine lost weight.
The antibody fragments worked to neutralize the infection. This serum has proven to work against Gamma variants.
The technology is being used by iSera Biologicals to help create a vaccine, and the drug is made from horse antibodies. It claims to cure COVID within 90 hours.
