Coronavirus antibodies made by llamas could be administered to Covid-19 patients in the form of nasal sprays or asthma-style inhalers to help combat the disease. Lab experiments have showed that the nanobodies adhere to the spike protein of SARS-CoV-2, the virus which causes Covid-19, effectively neutralising it. Early indicators reveal the nanobodies are effective in aerosol form, and can be administered to humans via nasal sprays or asthma-style inhalers. On average, the proteins are about a tenth the weight of most human antibodies and are also cheaper and easier to engineer. Human antibodies, like those of most mammals, including humans, have two chains (heavy and light).
