Scientists at the University Hospital of Lausanne and the Federal Polytechnic School of that Swiss city (EPFL) announced the discovery of a monoclonal antibody capable of neutralizing all variants of covid-19, including delta. The scientific discovery, published in the specialized journal “Cell Reports”, was achieved by isolating lymphocytes from patients with Covid-19.

The antibody is “one of the most potent so far identified against the SARS-CoV-2 coronavirus,” the EPFL said in a statement. According to the researchers, the antibody blocks peak proteins (which give the virus its characteristic “crown” shape) and thus prevents infection of lung cells, or impedes the viral replication process and allows the patient’s immune system to eliminate the body’s coronavirus.
Scientists also ensure that the new monoclonal antibody is more durable, as it offers protection for about six months, versus three or four weeks for other antibodies.
“This makes it an interesting preventive treatment for unvaccinated individuals at risk, or for vaccinated people who have not been able to produce an immune response,” the Swiss university’s statement said.
Immunocompromised patients, organ transplant recipients or patients with certain types of cancer could be protected against the coronavirus by receiving injections of the discovered antibody twice or three times a year, EPFL experts predicted.
Clinical trials of a drug based on these antibodies will begin in late 2022.
