As COVID-19 moves from a pandemic to an endemic disease, VOCs continue to pose a global challenge to healthcare due to their increased transmissibility and virulence, and the avoidance of immune immunity. Therefore, a group of Canadian scientists investigated the evolutionary processes involved in the formation of new SARS-CoV-2 VOCs and identified potential steps that could be taken to reduce the appearance of VOCs in the future.
