How do you create a vaccine without "change of function"?
You NEVER create a vaccine for something zoonotic that has not already crossed over to humans.
There are an almost infinite number of zoonotic viruses out there, and you don't start creating vaccines for things that are not endemic to humans already.
And if you were attempting to make a vaccine, you would have finished that first, before you started on changing the virus function to be more human compatible.
