Scientists have found evidence that the coronavirus may be mutating and adapting to humans. By analyzing over 5,300 coronavirus genomes from around the world, researchers identified two mutations in the spike protein that the virus uses to infect cells. While currently rare, these mutations could potentially allow the virus to spread more easily between people. Scientists are monitoring these mutations since vaccines currently target the spike protein, and changes could impact vaccine effectiveness. Ongoing global surveillance is needed to understand how the virus is evolving.
