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 fight disease.

According to another research published in the health research journal ‘Science’ in November 2020, some people, especially children, may have antibodies to fight the corona, which are reactive against the corona virus. These antibodies would have been made in people when they would have been infected with normal cold, viral fever etc. Whereas, according to a study published in Nature Communications in January 2022, people who"corona virus" href ="https://www.abplive.com/coronavirus-covid-19" data-type="interlinkingkeywords">Coronavirus produces high levels of immune cells, which may provide some degree of protection against COVID-19.
