A study found that people who catch the common cold can develop immunity to COVID-19.
According to the Guardian and Archyde.com, a British daily newspaper, on the 10th (local time), researchers at Imperial College London published a study in the academic journal Nature Communications showing that T cells produced by the common cold also have cross-immunity against COVID-19. T cells are a type of white blood cell that helps prevent infection.
The research team tested 52 family members of those who were confirmed by the gene amplification (PCR) test for re-infection 4 and 7 days after the first PCR test. The research team explained the background of the study, “I wanted to find out why some people get infected and others don’t get infected even if they are exposed to the Corona 19 virus.”
As a result, 26 people did not contract COVID-19, and they had significantly higher levels of cross-reactive T cells. In addition, it was confirmed that these T cells attack the internal protein of Corona 19, not the spike protein on the surface of the virus. Most of the vaccines currently supplied target the spike protein, but spikes are prone to mutations and can be ineffective due to omicron mutations. Professor Ajit Ralbani, co-author, said, “The internal protein that T cells (derived from the common cold) that we have identified undergoes relatively less mutation. We will provide a blueprint,” he said.
