The corona vir-us does not have the ability to infect all the people in the world. According to a new study, some people have T-cells in their body that will never be infected.
Scientists also claim that people who have symptoms of the mild coronavi-rus may also develop T cells and antibodies that will protect them from future infections.
The study, published in the journal Cell, found that many people develop anti-viral T cells because they are infected with different strains of the virus. This cell is able to resist corona. This capability is called ‘cross-reactivity’ in medicine, says the science-based website Science Alert.
A total of 40 blood samples were tested in the study. 20 of them have recovered after being infected with corona. Samples of the remaining 20 were collected between 2015 and 2016. Those who were infected by any other vi-rus. Those 20 people were not infected.
Alessandro Seth, a research assistant, said the T cells could show a strong immune response very quickly. Although the virus tries to spread throughout the body, the T cell’s immune system is able to resist it.
Studies have shown that 20 people who recover from corona have white blood cells and antibodies in their bodies. And in 50 per cent of the samples taken from 2015 to 2016, a T-cell called ‘CD4 +’ was found.
