The immune system prepares the body to launch a fast and powerful attack in response to any new virus attack.
“It’s very good news,” said the university’s chief of molecular immunology and chief researcher of the study, Michael Nussenwig.
Nussenwig added that expectations show that people are able to rapidly produce antibodies and fight infection in a large number of cases.
It is not clear how long the memory of the immune system that preserves the shape of the Corona virus, but Nussenzweig estimated that the immune system provides protection that lasts for years.
This explains that the number of those infected with the virus more than once is small.
When a person becomes infected with the Coronavirus, the human immune system launches a multiple attack targeting the virus.
The “T” cells represent one of the forms of protection, as they search for and destroy the infected cells in an attempt to contain the spread of the virus, while the “B” cells deliberately release the antibodies into the blood.
Once the infection ends in the body, the immune system stops fighting, but it remembers the infection by storing information about it in the “T” and “B” cells.
The study included 87 people with Coronavirus, and the researchers said that the antibodies diminished, to recede by more than a fifth from the peak level within 6 months.
Upon examining the immune system of the sample individuals, the researchers noted that six months after infection, the antibodies made by “B” cells had evolved to become more powerful than before.
