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.
Short chains of the molecules, which can be produced in large quantities in the laboratory, significantly reduced signs of Covid-19 when given to infected animal models, according to the study.
The nanobodies bind tightly to the virus, neutralising it in the laboratory, and could provide a cheaper and easier alternative to human antibodies taken from recovered from Covid-19 patients.
