When a person becomes infected with the coronavirus, the human immune system launches a multiple attack targeting the virus.
Cells are represented "The t" One of the forms of protection is that it seeks out and destroys the infected cells, in an attempt to contain the virus outbreak, as well as the cells "second" It proceeds to release antibodies into the blood.
Once the infection ends in the body, the immune system stops fighting, but remembers the infection by storing information about it in cells. "The t" Y"second".
The study included 87 people with coronaviruses, and the researchers said antibodies declined, falling more than a fifth from the peak level in 6 months.
When examining the subjects’ immune systems, the researchers noted that six months after infection, the antibodies produced by the cells developed. "second", To become more powerful than ever.

Researchers at Rockefeller University in New York City claimed that the immune system not only remembers the virus, but also develops the quality of antibodies after recovery, according to the British newspaper The Guardian.
The immune system prepares the body to launch a fast and powerful attack in response to any new virus attack.
“This is very good news,” said the university’s chief of molecular immunology and the study’s principal investigator, Michael Nussenwig.
Nussenwig added that expectations show that people can rapidly produce antibodies and fight infections in a large number of cases.
It is unclear how long the immune system’s memory that retains the Corona virus lasts, but Nussenzweig estimated that the immune system provides protection that lasts for years.
This explains why the number of people 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, since they seek out and destroy 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 remembers the infection by storing information about it in “T” and “B” cells.
The study included 87 people with coronaviruses, and the researchers said antibodies declined, falling more than a fifth from the peak level in 6 months.
When examining the immune systems of the individuals in the sample, the researchers noted that six months after infection, the antibodies produced by the “B” cells had evolved to become more powerful than before.
