The common cold is very common and bothers people a lot.
However, a new study suggests that a common cold in the past may provide some protection against the new corona virus, code 19.
The claim was made in a medical study conducted in the United States.
Research from the University of Rochester Medical Center has shown for the first time that the body can develop long-term immunity against the virus that causes code 19.

Research published in the journal Mbio shows that coronavirus infection produces B cells that can identify germs over a long period of time, as well as remember them in the future, while also producing antibodies to eliminate them. Are
That is, the next time the germs try to re-enter the body, these B cells become active and clear them before the onset of the disease.
B cells usually survive for decades, which may protect those who beat code 19 against the disease for a long time, but more research is needed.
Cross-reactivity of B cells was also reported for the first time in this study, meaning that B cells that attack the common cold may seem to recognize the new corona virus.
Researchers believe that this means that people infected with the common corona virus, which causes the common cold (almost every one of them), have some resistance to code 19.
“When we looked at blood samples from people who had recovered from code 19, it looked like there were a number of B cells that recognized the new corona virus and were attacking them very quickly,” he said. Can produce antibodies.
The study’s findings were based on a comparison of blood samples (collected 6 to 10 years ago) from 26 patients and 21 healthy people who recovered from Code 19.

The samples tested antibodies targeting specific parts of B cells and spike proteins, the main weapon of the corona virus to infect cells.
These spike proteins work somewhat differently in all types of corona viruses, but part of it is almost identical to all S2 viruses.
These B cells are able to identify this part of the spike proteins of different types of corona virus.
The study did not say how much protection people get from these B cells and what effects they might have on the disease.
The researchers said that now we need to see if these pre-existing B-cells in the body cause mild to moderate and short-lived corona viruses or to what extent they can help the efficacy of the Code 19 vaccine.
