A novel coronavirus found in Russian bats has scientists calling for an urgent effort in generalized vaccine development. Otherwise, they caution, another pandemic might be triggered by a deadly animal virus spilling over to humans.
It's not yet clear if the virus that infects these bats can spill over to humans in the real world, but initial findings in the lab suggest it's certainly possible.
While Khosta-1 was not able to infect human cells on its own in the lab, when a protein-eating enzyme was artificially added to the scene, the virus was suddenly able to gain entry to human cells using a different gate. Obviously, that's not a good thing. If this viral reservoir spills over to humans, our current coronavirus vaccines that mainly focus on the ACE2 receptor may no longer ward off infection.
