The study found that these people had a rapid immune response in their nasal tissues that protected the body from the virus. The experiment, which involved 36 volunteers, was published in the journal Nature.
Volunteers were infected with the pre-alpha strain of SARS-CoV-2 and their immune responses were monitored.
Sixteen participants were unvaccinated and had no evidence of previous infection. Analysis of blood and nasal swabs revealed three categories of infection: transient, persistent and abortive.
In the second group, the virus was unable to gain a foothold due to the rapid immune response in the nasal tissues.
Let us recall that Brazilian scientists previously established that a vegan or vegetarian diet reduces the likelihood of contracting coronavirus by 39% due to the high level of antioxidants and polyphenols that have a positive effect on the immune system.
