Not antibodies but T-cells are a guarantee of immunity against corona, know how it works


New delhi date. 24 July 2020, Friday

In an important vaccine data released this week, T-cells are considered very important for corona immunity. So let’s find out what these T-cells are after all, how they work and why they are considered more reliable than antibodies against coronary infections.

Important for an effective vaccine against corona

In fact, it is believed that the body develops immunity to the virus if antibodies are found in the body during testing for the corona vaccine. However AstraZeneca Plc, Pfizer Inc. And its partner BioNTech SE, as well as China's CanSino Biologics Inc. The data associated with the Corona vaccine suggest that the presence of T-cells rather than antibodies is more important for immunity. Simply put, if T-cells are active in the body, it is a guarantee of immunity for a very long time.

What are T-cells

T-cells are also called T-lymphocytes. It is a type of leukocyte i.e. white blood cell which is a very important part of our immune system. T-cells directly attack infected cells and activate other immune cells.

Is it more reliable than antibodies?

Research into Corona's case has revealed that antibodies are no longer active and their numbers are declining rapidly. T-cells, on the other hand, completely eliminate infected cells. He remembers the disease for decades and responds the same way he did the first time he attacked the body. People who developed a T-cell response to SARS in 2003, a type of corona virus, are still active 17 years after the onset of the disease. This means that those people will not be infected with SARS again.

The mystery of the extent of the transition will be solved

Corona virus is attacking patients in different ways. Some people feel a very mild transition while some have a very heavy transition. To the extent that the patient also dies. This may be due to the presence of T-cells in the patient's body. However more research is needed to make a definitive claim on this.
