New research indicates that recovering coronavirus patients likely have a strong immune memory that lasts for at least eight months, and this memory depends on more than just antibodies as it includes white blood cells known as T cells and B cells that have amazing memory abilities..
According to a newspaper report sciencealert Together, these layers of protection enable the immune system to recognize the Corona virus and re-attack it if it invades again, and thus prevent another infection, to assess how long it takes immunity to the virus across these different layers of the immune system, and scientists measured the number and types of immune cells that recovered from Coronavirus after months of their illness.
Although the research has not yet been reviewed, the hope is that those who have already become infected will likely not become ill again for some time..
“Most people make most parts of the immune response to this virus, and those parts are still after about six to eight months,” said Shane Crotty, a virologist at La Jolla Institute of Immunology in California and one of the study’s authors. “As the antibodies diminish, the T cells and cells persist. B.
Some research has suggested that the blood proteins in the coronavirus antibodies that protect the body from subsequent infection wear off within a few months..
But concerns about these findings could diminish the role of killer T cells, which identify and destroy infected cells, as well as helper T cells that inform B cells about how to manufacture new antibodies..
Nearly 40 of the participants donated blood multiple times, some more than six months after their illness. This enabled researchers to assess how the patients’ immune responses changed over time, their results showed that the levels of T-cells specific to the Coronavirus decreased slightly between four and six months, and then stabilized after that the researchers believe that it is likely that the T cells and antibodies remain consistent after the six-month mark. This is because this is typical for other viruses.
