Research Chair of Applied Pathogen Ecology at University College Cork: “One of the things I find amazing is #Covid19 really gives your immune system a very big hit, it takes out your T cells, your dendritic cells and a lot of those modes of action or very similar to the modes of action that cause Long Covid... This current wave is not just about lack of exposure, it’s also about the fact that none of us have quite the same immune system as we used to have."
