Covid: Immune therapy from llamas shows promise


Fifi the 'Franklin llama' lives at a farm facility at the University of Reading

A Covid therapy derived from a llama named Fifi has shown "significant potential" in early trials.It is a treatment made of "nanobodies", small, simpler versions of antibodies, which llamas and camels produce naturally in response to infection.Once the therapy has been tested in humans, scientists say, it could be given as a simple nasal spray - to treat and even prevent early infection.Prof James Naismith described nanobodies as "fantastically exciting".
