Why are some people naturally immune to COVID? Neville Sanjana, PhD, an associate professor of biology at NYU who worked on the study that used CRISPR to find genetic mutations that thwart SARS-CoV-2, observed, You're not going to go in and CRISPR-edit peoples genes to shield them from the virus. At the same time, theyll look specifically at an existing list of genes they suspect might be the culpritsgenes that if different from usual would just make sense to infer resistance. Some people are unusually resilient to the coronavirus, . But assume the pre-existing T cells are accustomed to automatics, and a SARS-CoV-2 encounter is like hopping into the drivers seat of one, and you can see how they would launch a much quicker and stronger immune attack.

As reported by The Mail on Sunday last month, flu has all but disappeared for the second year running and scientists now suggest that Covid vaccination, or infection, might rev the immune system and guard against flu infection as a welcome secondary benefit. The pandemic triggered a huge surge to 91 per cent. In addition: Older adults are at highest risk of getting very sick from COVID-19. This is despite there being a clear therapeutic goal. But scientists aren't sure why certain people weather Covid-19 unscathed. Most Covid vaccines mimic the spike protein found on the outer surface of the virus cells, which provides the route by which the viral cells infect healthy ones and set up camp in the body. Why COVID-19 Makes Some People Sicker Than Others - The Atlantic March 31, 2022 by Jenny Sugar. As part of their work, the scientists used serum samples provided by people who did not have COVID-19. A person's risk of severe illness from COVID-19 increases as the number .
