Thats showing to be the case for a series of studies taking a look at how long antibodies persist in individuals who have been contaminated with the coronavirus. Three current research studies– from China, Britain and now the United States– have actually called into question how long individuals carry antibodies after infection. They tracked antibodies in 34 individuals with coronaviru and discovered that the average antibody levels dropped to half of where they started over a duration of about 2 and a half months. They discover that 90% of those people had antibody responses that lasted at least three months. The period of an antibody action might depend at least in part on whether an infection led to a substantial illness– and a substantial immune reaction.

They discover that 90% of those individuals had antibody responses that lasted at least 3 months. “Those are cells that do not in fact make any antibodies unless the virus comes back and then they see that infection again,” Krammer says. The duration of an antibody response may depend at least in part on whether an infection led to a considerable health problem– and a substantial immune response.
