6 days ago · World-First Experiment Reveals Why Some People Never Get COVID-19. A detailed comparison of COVID-19 cases has finally provided insight into why some individuals have yet to endure so much as a sniffle from a virus that brought much of the world to its knees.
- Do Genetics Make Some People Immune to Covid-19?
- Do Prior Viral Infections Provide Covid-19 Immunity?
- Other Reasons People Haven’T Tested Positive
An international team of researchers is in the process of recruiting potential study participants who fit the so-called “never COVID” cohort. They are looking for people who were exposed to someone with COVID-19 for a lengthy period, without protection, and never got sick or tested positive for the virus. For example, in some cases an entire family...
Another study, published in Nature Communications, shows that some individuals have what might be a pre-existing immunity to COVID-19. “The hypothesis is that people with increased exposure to other versions of coronaviruses will have ‘premade’ T cells that cross-react with COVID-19 and are able to quickly respond to COVID-19 infection,” Sensenig e...
In addition to potential immune system or genetic factors, other people may have never developed COVID-19 if they evade exposure. For example, some people have had the ability to work from home or practice rigorous social distancing. Masking and following vaccination and booster recommendations from public health experts prevented many infections, ...

Jan 23, 2023 · The study says that while most global research has focused on understanding why some people get severely ill, or die, from COVID, it’s also vital to understand why a small population doesn’t get it at all, or shows no symptoms when infected.

Researchers have shed new light on why some people do not get Covid-19. In a world-first, 36 healthy people who had never had coronavirus were deliberately given the virus that causes the disease.
Jun 19, 2024 · Scientists have discovered novel immune responses that help explain how some individuals avoid getting COVID-19. Using single-cell sequencing, researchers from the Wellcome Sanger Institute ...
Sep 12, 2022 · The most promising candidates are those who have defied all logic in not catching Covid despite being at high risk: health care workers constantly exposed to Covid-positive patients, or those...
Apr 21, 2022 · Experts stressed that research to determine why some people get COVID-19 while others don’t is still very much underway, and no one should rely on any of the hypotheses for protection.
