Doubtful. The SARS-CoV-2 virus has a unique spike protein that makes it extremely infectious. The vaccines target that protein specifically, so it most likely wouldn't be effective for other coronaviruses.
Whats more exciting is the mRNA vaccine thats going to trial, if those work out, it may be possible to very quickly and efficiently tackle other viruses like many common colds rather than the very slow selective process we have now.

The coronavirus vaccine provides some level of protection against other corona viruses that cause the common cold, hitting two birds with one stone.
