A research team in Canada has announced that antibodies present in the plasma of recovering coronavirus patients fade rapidly after recovery, and its effectiveness is severely diminished ten weeks after first experiencing symptoms. The discovery holds both importance to current methods in fighting those who are infected with COVID as well the quest to find a vaccine for the disease.
The study was published in mBio, an open-access journal of the American Society for Microbiology and the research analyzed findings from an earlier cross-sectional study that included more than 100 patients.
Currently, plasma therapy is being used as a way to fight the “spike proteins” that allow the virus to latch onto the body’s cells and invade them. The antibodies in the plasma bind to the spike proteins, making them unable to gain access to the cells and infect the host.
