New research that is more than important to understand the SARS-CoV-2 virus and that this time could open the door to why certain people seem immune to covid-19. As published in the magazine Nature, the common cold would serve as a barrier against contagion por coronavirus with the importance that this would derive in the creation of a second generation universal vaccine.
A study carried out by Imperial College London has taken a huge step forward in understanding the covid-19 pandemic. Under constant surveillance since September 2020 of a group of people who lived with infected by coronavirus, the reported analyzes showed that about half of them were not infected by the same cause.
The reason, the immune response offered by the common cold capable of acting against the attempt of SARS-CoV-2 to enter the body. A reasoned defense for presence of T cells arrivals of the coronavirus that causes the cold and that act as a barrier not only against the strongest symptoms but also against the contagion itself.
It could be the first step of a more effective vaccine
Therefore, this research could be more than important in the face of finding a second-generation vaccine that would limit infections instead of symptoms, as do the existing ones today. “T-cell responses persist longer than antibody responses, which decline within a few months of vaccination,” the study notes.
“The best treatment against covid-19 is to be vaccinated”
Of course, still cautiously, since this is only the first step pending more confirmations, the researchers call for the best treatment against covid-19 to “be vaccinated”.
“Exposure to the SARS-CoV-2 virus does not always lead to infection, and we wanted to understand why. We found that high levels of pre-existing T cells, created by the body when infected with other human coronaviruses such as the common cold, can protect against infection with the SARS-CoV-2 virus”, they have highlighted in what is one of the great unknowns of why certain people seem ‘immune’ to the pandemic.
A study suggests that the coronavirus can hardly spread suspended in the air in closed environments
