If you’ve ever had a cold, your immune system may already know how to fight COVID-19

[Natural News]: Since the common cold is a type of coronavirus, bearing many of the same features and attributes as the novel coronavirus, experts say that many people’s immune systems have already been “trained” to ward off infection without the need for pharmaceutical drugs or vaccines.

“Your immune system’s ‘memory’ T cells keep track of the viruses they have seen before,” researchers at LJI explain. “This immune cell memory gives the cells a head start in recognizing and fighting off repeat invaders.”

Published Aug. 4 in the journal Science, the LJI study breaks down the science behind how the immune system learns about diseases after being exposed to them. If a strong T cell response occurs in response to the common cold, it found, then the immune system is already primed to handle exposure to the Wuhan coronavirus (COVID-19).

“We have now proven that, in some people, pre-existing T cell memory against common cold coronaviruses can cross-recognize SARS-CoV-2, down to the exact molecular structures,” says Daniela Weiskopf, PhD, a research assistant professor at LJI who helped co-lead the new research alongside professor Alessandro Sette, Dr. Biol. Sci.

“This could help explain why some people show milder symptoms of disease while others get severely sick.”...<<<Read The Full Article Here>>>...
