Some people exposed to coronavirus didn't get ill. Now researchers want to use that in vaccines.
Understanding how some people naturally resist Covid infection, despite clearly being exposed to the virus, could lead to better vaccines, say researchers.
Despite being in a high-risk environment, not everyone in the study came down with Covid. The results,But around one-in-10 had signs of being exposed, but never had symptoms, never tested positive and never developed Covid-fighting antibodies in their blood. These T-cells were able to spot a different part of the virus than the bit most of the current vaccines train the immune system to find.
It means targeting these proteins with a vaccine could give some protection against all coronaviruses and new Covid variants.
