The Israeli government is reporting this morning that the country’s Institute for Biological Research has made a breakthrough in the development of a potential treatment against SARS-CoV-2, the virus which causes COVID-19. Scientists there have isolated a ‘monoclonal neutralizing antibody’ which could potentially neutralize the virus after infection. The antibody was obtained from the blood of an infected patient. It is called monoclonal because it is generated from a single cell — which could allow vast quantities of the antibody to be produced quickly.
Is it the breakthrough that could make all the difference? Treatment of novel viruses with monoclonal neutralizing antibodies has been under development for some time, notably for Ebola, Sars and Mers. For Ebola in particular, treatment has been shown to boost the production of antibodies in a patient and to reduce viral load — in one case two US patients who had been infected with Ebola in West Africa improved after treatment, although it wasn’t clear whether this was because of the treatment or because of their own immune systems. But most of the research so far has been limited to experiments in test tubes and in laboratory animals. A paper by Chinese and US government scientists from 2017 gave a progress report, reviewing various experiments.
