New research suggests immunity to the coronavirus may last years.
In a study, which has not yet been peer-reviewed, researchers found that the amount of “B Cells” in patients infected with the coronavirus had actually increased six to eight months after infection. B Cells are a type of “memory cell” in the immune system that remembers a pathogen. If a person is reinfected with a pathogen, the B Cells will then produce antibodies to fight it.
