Scientists have expressed “cautious optimism” after a new study showed that patients may have a level of immunity against “Covid-19” for at least 6 months after symptoms appear.
Scientists from the United Kingdom’s Coronavirus Immunology Consortium (UKCIC) worked with Public Health England and the University of Birmingham to compare the cellular immunity to the coronavirus in patients.
Specifically, they analyzed the T cells of coronavirus patients, which work with antibodies in the immune system to protect against infection.
They found that the “Covid-19” patients had small effects of T-cell immunity against the virus, for up to six months after the initial infection.
And there have already been reports of people infected with the Coronavirus twice, raising fears that the herd immunity strategy may not work.
But the latest results have made some scientists moderately optimistic about the length of immunity to the deadly infection.

UKCIC President, Professor Paul Moss, said: “Understanding what constitutes effective immunity to SARS-CoV-2 is very important, to allow us to understand how vulnerable individuals are to reinfection and to help us develop more effective vaccines for“ Covid-19 ”. We know, our study is the first in the world to show the survival of strong cellular immunity for six months after infection, in individuals who have suffered from “Covid-19″ mild / moderate or without symptoms. ”
“Our knowledge of SARS-CoV-2 infection is increasing all the time. While our results make us cautiously optimistic about the strength and length of immunity generated after SARS-CoV-2 infection, this is only one piece of the puzzle. There is still a lot to learn before we get it,” he added. A full understanding of how immunity against “Covid-19” works.
And cellular immunity was described as a very important piece of the puzzle in the fight against the Corona virus.
However, more research is needed to reveal exactly how long patients remain immune to the Coronavirus.
Meanwhile, a high fever, a new cough and a change in the sense of smell or taste are the most common early symptoms of Coronavirus.
In addition to the more common signs, some patients have also reported sore throats, headaches and even hiccups.
