Can we get immunity to fight against corona even from normal cold? Everyone comes in the grip of cold and flu at one time or the other. Now the question arises whether they strengthen the immune system or not. In fact, even normal cold is caused by the virus of the same family, which causes corona infection. A study has found that immune cells obtained from previous colds can help in fighting the corona-causing virus.
According to a study by the National Institute of Allergy and Infectious Diseases, minor corona infection is seen in some people as compared to others. You must have also seen that some people get terrible symptoms of corona, while some people do not even experience the symptoms of this infection. Now the question is how does corona harm someone less and someone more.
How do memory cells work?
In fact, when our body fights a virus such as the common cold, it retains the disease-fighting cells as memory cells. The next time a person comes under the grip of the same virus once again, the memory cell recognizes it and gets ready to fight the disease again. Memory cells give the immune system a jump start to combat disease.
Memory Cells Helpful in Fighting the Virus!
A team of researchers tested blood samples to identify these memory cells. Memory cells can recognize the SARS-CoV-2 virus, which causes the Covid-19 virus. Researchers said that more research is needed to find out how big a role memory cells play in fighting Kovid-19.
Antibody helps in fighting corona
According to another research published in the health research journal ‘Science’ in November 2020, some people, especially children, may have antibodies that are reactive against the corona virus to fight the corona. These antibodies would have been made in people when they would have been infected with normal cold, viral fever etc. At the same time, according to a study published in Nature Communications in January 2022, people who corona virus They produce high levels of immune cells, they can get some degree of protection from Kovid-19.
