Researchers in Japan have found two types of antibodies derived from alpacas that are effective against all SARS-CoV-2 variants.
The derived antibodies from the South American animal are expected to be put into practical use within the next two years.
The researchers are from Kyoto, and they published their research in the journal Nature on July 6.
Antibodies are proteins used by the immune system that bind to pathogenic viruses and bacteria so that they cannot bind to our cells. Alpacas have significantly smaller antibodies than humans and the researchers believe that their nanobodies (a single-domain antibody)  bind to SARS-CoV-2, the virus that causes COVID-19, easier than human antibodies….
