A recent study shows that particular T cells were discovered in all subjects who recovered from SARS 17 years ago and in more than half of both SARS-CoV-1 and SARS-CoV-2.
About The Study
The study was carried out by Singapore scientists. They discovered that T cell immunity specific to SARS-CoV 2 is present in recovered COVID-19 and SARS patients and uninfected people. The study was published in Nature.
T cells, along with other antibodies, are part of the human immune system that fights infections.
T cells directly target and kill infected cells.
The study revealed that those particular T cells are present in all subjects who recovered from SARS nearly two decades ago, and in more than half of both SARS-CoV-1 and SARS-CoV-2 uninfected individuals that were tested.
The discovery suggests that a level of already existing SARS-CoV-2 immunity exists in the general population.
The researchers inferred that infection and exposure to coronaviruses result in long-lasting memory T cells, which can help ease the ongoing pandemic situation. That might be because cross-reactive immunity resulted from exposure to other coronaviruses, like the ones that provoke the common cold.
According to the researchers, it is crucial to understand if the study’s findings can help explain why some people are better at controlling the infection than others.
The coronavirus pandemic took the world by surprise, and its effects were severe all across the globe, in big, wealthy countries and regions under development alike.
You must understand the pandemic isn’t gone. It is still a real threat that we should avoid carefully. The risk of infection is high, and the virus’s lethality was proven, so you should wear a mask whenever you go out and follow necessary hygiene measures to protect yourself and your dear ones.
