A research in Australia means that sotrovimab, a therapy for covid, could trigger the coronavirus to amass mutations that allow it to withstand the drug.
Sotrovimab neutralises SARS-CoV-2’s spike protein, which the virus makes use of to enter cells. Given by a drip, sotrovimab could be administered to folks inside 5 days of their an infection to forestall signs from changing into extreme.

Eight of the individuals who had been handled persistently examined constructive for SARS-CoV-2, and had airway samples collected earlier than and after they acquired sotrovimab.
In 4 of those sufferers, SARS-CoV-2 developed spike mutations between six and 13 days after sotrovimab was administered, with these genetic modifications making the drug ‘successfully inactive’, mentioned Rockett, as reported in The Guardian.
