Monoclonal antibodies are playing a key therapeutic role in the treatment of some Covid-19 patients, but new research suggests that nanobodies derived from llamas could provide an alternative to monoclonal antibodies through a more effective delivery method—inhalation.

French researchers are using tiny antibody particles extracted from the family of animals that includes camels and llamas to produce a test they say can detect if patients have Covid-19 faster and more accurately than existing methods.

Nanobodies derived from llamas have neutralized the SARS-CoV-2 spike in the lab, effectively neutralizing the virus, according to research from the UK’s Rosalind Franklin Institute.

Scientists in Sweden are hoping an alpaca named Tyson can help deliver a knockout blow in the fight to develop a treatment or vaccine against the novel coronavirus.

The U.S. FDA approved Cablivi in combination with plasma exchange and immunosuppression for treating acquired thrombotic thrombocytopenic purpura (aTTP) in adults.
