| Popular science: why some people are born immune to the new coronavirus |
Xinhua News Agency, Beijing, July 16th.
"Reference News" published a report on the 16th by the Buenos Aires Economic News Network, Argentina.
"There may be people who are born immune to the new crown virus without being vaccinated or infected
.
" The summary is as follows:
A new study by MedGenome, a genomic data provider, analyzes why some people who are not infected with the new coronavirus and have not been vaccinated are immune to the disease, or at least avoid serious symptoms
.
The object of this study is the T cells present in the human body
The research paper was published by the British journal "Scientific Reports" and the author is MedGenome scientists in the United States and India
.
The article stated: "Our research results indicate that many people may have SARS-CoV-2 reactive T cells due to previous exposure to influenza virus and cytomegalovirus
A study conducted last year has suggested the possibility that a part of the population has immune cells that can at least partially recognize the new coronavirus that causes new coronary pneumonia
.
This possibility opens up a new way to find immunity that can overcome the epidemic
People who can prevent the new coronavirus from entering their bodies or avoid serious symptoms have been found before
.
Those who are known to be immune include those who have been vaccinated or have been infected with the disease
Co-author of the study, Alessandro Setter of the La Jolla Institute of Immunology in California, said: “We found that about half of people who have never been exposed to SARS-CoV-2 have some degree of T cell reactivity
.
"
This means that some research target populations seem to have immune cells that can recognize a certain part of the new coronavirus, which may give them an advantage in fighting infection
Maria Fernanda Gutierrez, a virologist at the Catholic University of Javieriana in Colombia, told CNN that when the human body has previously been in contact with another pathogen with very similar characteristics, it is targeted.
In other words, when an unknown pathogen enters the human body, the immune system will mistake it for the pathogen it has encountered before and defend against this new pathogen
Focus on the new crown pneumonia epidemic
