2-min readIt is a treatment made of "nanobodies", small, simpler versions of antibodies, which llamas and camels produce naturally in response to infection.

The treatment has, so far, been tested only in those lab animals, but Public Health England said it was among the "most effective SARS-CoV-2 neutralising agents" it had ever tested. Just like our own antibodies, virus-specific nanobodies latch on to and bind to viruses and bacteria that invade our bodies. This binding essentially tags an invading virus with an immune "red flag", to allow the rest of the body's immune armoury to target it for destruction.

"We need more data on efficacy and safety before we move to human trials," she added. "However it's very promising nonetheless and the fact it may be cheaper and easier to administer is a plus. Covid-19 will be, unfortunately, with us for a while yet, so more treatments will be needed."published their research in the journal Nature Communications
