Perhaps the medically knowledgeable would care to comment on this:
People who have previously had Covid or been vaccinated have T-cells in their system that work well against omicron, a new study suggests.
T-cells are a form of immunity that are longer-lasting than antibodies, and although they do not stop infection, they prevent the virus from causing severe disease and death.
This seems so obvious to me as to not be worth wasting the pixels upon. True, this is probably because once we get to the nitty gritty I know nothing about biology. So, those who actually do know. This is so obvious? Or, actually, no, it’s really new news?
