Honkman…thank you for the thoughful reply and given your background I trust it 
There are to bio-tech firms here in Sorrento Valley that have sequenced the virus and are working on vaccines, but do not expect them to be available for at least a year, and that would be fast-tracking them.
I heard from a friend this afternoon that some researchers are actually looking at a vaccine developed by Nils Pedersen’s team at the UC Davis Vet School to deal with FIP, Feline Infectious Peritonitius, which is a (usually fatal to cats) coronavirus. Apparently the feline FIP vaccine has has a pretty good success rate with cats and researchers are trying to determine if they can use any of the components from the FIP vaccine in the development of a COVID-19 vaccine. Sounds like kind of a wild idea to me but an interesting anecdote
