A recent symposium was held in the UK (28-29 April 2021) that examined various aspects of COVID-19 and our immunologic system. (Collaborative Covid Immunology/ UK Covid Immunology Consortium [UK- CIC] and the British Society for Immunology.). While the immune responses to COVID-19 are clear, we have little information about potential long-term effects. Which is why I will share the results of several very interesting papers presented at the symposium.
