New Study Finds Why Some People Got Covid And Others Didn't

One of the key questions on everyone's mind throughout the pandemic was why some people avoided getting COVID, while others caught the virus multiple times.

Writing in The Conversation, Principal Research Fellow on Respiratory Medicine at the University College London, Marko Nikolic, and the institute's Research Fellow on Molecular and Cellular Biology, Kaylee Worlock, explain that in a controlled trial, UCL in partnership with Sanger Institute and Imperial College London identified a specific gene called HLA-DQA2, "which was expressed at a much higher level in the volunteers who did not go on to develop a sustained infection and could hence be used as a marker of protection".

The pair noted that the findings will help the global community fill in some knowledge gaps and paint a detailed picture regarding how the human body reacts to a new virus, "particularly in the first couple of days of an infection, which is crucial".
