If it really came from bats or wolf pups, people have been in contact with and studied both species for years.
We should be getting far closer to a cure or at least a vaccine. But we keep coming back to hyrdroxychloroquine.
We don’t need a vaccine, the disease would need a colony of a very specific species of bat to remain in the environment after it runs its course through humans.
And certainly a vaccine that doesn’t have a decade of testing would be effectively intentionally attempting to kill every diabetic it was given too.
Not that all the people advocating that irresponsible lunacy would have qualms about that.
