When a user is inflamed with a virus, their body produces antibodies to fight infection. After healing, antibodies can remain in the user’s blood plasma for months or even years. In convalescence plasma treatment, other newly ill people, in this case with coronavirus – get plasma from a recovered user in the hope that they have their own ability to fight the virus and restrict its severity.
“While many clinical trials are underway to better understand whether convalescence plasma is clinically favorable for coVID-19 treatment, a key question is when it is maximum effectiveness in collecting plasma from donors based on the presence of antibodies that help fight the virus. “Renée Bazin, PhD, of the Hema-Québec Blood Center (Canada) and author of the study said. “According to our findings, antibodies that oppose the new coronavirus are not eternal. “
