Imperial College researchers’ in a recent study claimed that high levels of T-cells from common cold coronaviruses can provide protection against Covid-19. 

These results, they said, could help provide an outline for the development of new vaccines. 

T-cells provide long-lasting immunity to corona. But they warn that no one should rely solely on T-cells. 

Vaccination is still the best way for people to be vaccinated against corona. T-cells are a type of white blood cell that helps protect the body from infection.

 The study, which began in September 2020, looked at levels of cross-reactive T-cells developed by previous common colds.

Experts tested the experiment on 52 people. Of these, 26 people with high T-cells survived coronavirus. The other 26 people who were diagnosed with corona had lower rates of T-cells.
