Scientists have detected a mutation in the SARS-CoV-2 virus that has the potential to not trap antibodies developed to fight infections.
Experts at the Fred Hutchinson Cancer Research Center mapped all possible Covid-19 mutations that could prevent the binding of three monoclonal antibodies (created in the laboratory and administered to patients as part of a special treatment), reported Sputnik in the Nature magazine.
It turns out that a series of mutations affect a protein segment called the receptor-binding domain (RBD) that the virus uses to enter cells.
One of these mutations hid the virus from the entire antibody cocktail, while others managed to get rid of one of the three antibodies.
Experts noted that some of these changes are common in people infected with Covid-19, but a mutation was detected in the Netherlands and Denmark that resists the entire antibody sequence.
