Llama antibodies in a nasal spray found to be effective Covid-19 treatment 

Antibodies sourced in llamas and delivered with a nasal spray are effective in helping fight off Covid-19.

Tiny antibodies produced by llamas could provide a new frontline treatment against coronavirus in the form of a nasal spray, research suggests.

Scientists at the Rosalind Franklin Institute have found that the nanobodies - a smaller, simple form of antibody generated by llamas and camels - can effectively target the Sars-CoV-2 virus that causes Covid-19.
