Corona human resistance has increased!

Being negative in Coronavai’s antibody test is not the last word. There is still some talk. That is, negative people may have some amount of immunity in their body. A new study has revealed such a possibility. According to the Swedish study, previous tests have shown that the human body is more immune to coronavirus, but in reality more people are protected. News from the BBC.

Researchers at the Karolinska Institutet in Sweden tested 200 people for antibodies and T-cells. Some of them were blood donors. The rest were selected from among those infected with the corona in Sweden. They originally returned from infected areas such as northern Italy. Antibody tests identified two specific T-cells in each person who tested positive, which destroyed the infected cells once they were identified. At the same time, this tendency has been observed in patients with mild symptoms or without symptoms of Kavid-19. However, it is not yet clear whether these T-cells only protect the infected person or prevent others from becoming infected through them.

From here, scientists speculate that larger populations may have some degree of corona immunity than antibody test data. They think that the antibody response of these people may have faded. Or it is not recognizable in existing test methods. Danny Altman, a professor at Imperial College London, described the study as “vigorous, impressive and comprehensive”.

Researchers at the Karolinska Institutet in Sweden have conducted experiments to detect the presence of both antibodies and T-cells in the human body. It has been found that although there are no antibodies, many people have the presence of T-cells in their body. This T-cell identifies and destroys infected cells in the corona. Two such T-cells were found in each patient with antibodies. One explanation for the fact that there are T-cells, but no antibodies, is that these human bodies may not need to produce antibodies.

This means that the number of people who have developed immunity in previous tests based on the presence of antibodies is actually higher than that.
