虽然新冠疫苗已经出现，但还是要对不停进化病毒保持警惕

冠状病毒虽然不会像流感病毒那样变异，但是宾夕法尼亚州立大学的Andrew F. Read说：但随着时间的推移，病毒可能会对现有疫苗产生耐药性。长久以来，医学一直在和细菌、病毒做斗争，因为这些生物体会不断发生变异，进化出新的特性。研究人员敦促大家一定要保持警惕！

The coronavirus is not a shape shifter like the flu virus, but it could become vaccine resistant over time. But vaccines won’t put an end to the evolution of this coronavirus, as David A. Kennedy and Andrew F. Read of The Pennsylvania State University, specialists in viral resistance to vaccines, wrote in PLoS Biology recently. Instead, they could even drive new evolutionary change. As medicine battles bacteria and viruses, those organisms continue to undergo mutations and evolve new characteristics. That prompts researchers to urge vigilance.  source
