Those who contracted Covid after being vaccinated would be particularly well protected against the virus, including the Omicron variant, according to an Austrian study.
It is a very encouraging study which was carried out at the University of Innsbruck in Austria on 100 participants and which reports the German magazine Focus. Indeed, it would show that it is possible to achieve what is called superimmunity against Covid, a superimmunity which would also be effective against the Omicron variant and all the others to come.
To achieve this, two factors are important: on the one hand, you have to be vaccinated, and on the other hand, you have to be sick with Covid. The order doesn’t matter. Suddenly, a doubly vaccinated person who still contracts the virus has a good chance of being considered “super-immune”. Just like a sick person who was then vaccinated.
This so-called “hybrid” immunity would neutralize all forms of Covid, including Omicron, according to the authors of study. However, these results still need to be evaluated by independent experts.
But they join those of a study by Oregon researchers published in mid-December in the Journal of the American Medical Association and which demonstrates that people fully vaccinated against Covid-19 would develop exceptional immunity if they subsequently contract the virus. The protection thus granted would be 1000 to 2000% higher than that of uninfected patients, according to its authors.
A British study looked at people who do not catch the coronavirus even from having been in contact with sick people by examining 731 employees of British hospitals. Published in the scientific journal “Nature”, She explains that certain cells and special proteins are responsible for this phenomenon. Indeed, the team of researchers, led by Leo Swadling, found that people who remained healthy had a large number of specific T cells (a category of white blood cells) and IFI 27 immune proteins in their bodies, which would thus have succeeded in blocking the infection before it broke out.
Cited in the “St. Galler Tagblatt“, Doctor Swadling puts the results into perspective:” in March 2020, we analyzed the virus from Wuhan. We do not know if immunity is also present for later variants like Delta or Omicron. But it is clear that in the summer of 2020, around 10 to 20% of those tested were resistant to Sars-CoV-2 ”.
