Why some people seem to be completelysheltered from CovidWhile others become seriously ill? It's a question that has troubled health professionals throughout thecoronavirus pandemic, And find the answer could be a big step forward to control the propagation of the virus. There is probably only one explanation, but the new research offers a new evidence of a promising theory:previous vaccines could protect you from contracting Covid-19.

"When we examined in the COVID disease, we found thatPeople who had front vaccinations With a variety of vaccines for pneumococcus, influenza, hepatitis and others, seem to have a lower risk of contracting a Covid disease, "Andrew Badley, MD, an infectious disease specialist at the Mayo Clinic, told CNN on 10 August

Although there have been promising developments, we still do not have acoronavirus vaccine. And even when we do it, the experts warn that it will probably not be able tocompletely protect against the virus we. But as Badley explains, vaccines for other illnesses could be part of what immunologists call "immune training" or strengthen your immune system and better prepare to combat infections, even new pathogens such as COVID-19.

"A good analogy is to think of your immune system like a muscle," Badley said. "The more you exercise this muscle, the more it will be when you need it. »

As CNN points out, there have been further studies to determine whether previous vaccines could prevent people from Covid-19 contracts, or even prevent them from becoming seriously ill with the virus. A July study published in the journalActs of the National Academy of Sciences of the United States of America found a correlation between a tuberculosis vaccine andLower mortality COVID.

There are not just vaccines that could confer some degree of coronavirus immunity, however. The researchers are also looking on the role that T lymphocytes could play in Covid prevention for people who have been naturally exposed to others, less serious coronavirus-person who has colds, for example. These are these peopleThe immune system can recognize COVID-19 Despite never meet this specific strain of the virus before.

While scientists work on an effective wayCOVID vaccineAnd researchers continue to study innate immunity to the virus, it is important to behave as if you can be infected. This means glue to the security measures described by health experts and state officials, including the portFacial masks in public and social distancing. And to know who masks to avoid,This face of recovery is actually worse than no mask to all, reveals a study.
