Researchers in Brazil and other countries around the world are exploring the possibility of using antibodies extracted from llamas and other camelids to develop a treatment for Covid-19.

These animals develop antibodies that are smaller than those produced by humans and thus can be easily manipulated and transformed into medications. Llama antibodies are already used to treat neurodegenerative diseases.

The process of obtaining these antibodies consists of vaccinating llamas with a mixture of proteins from the coronavirus, before extracting the antibodies the animal produces.
