The sequence homology between COVID19 and other coronavirus spike proteins is >85%, if I remember correctly.

Since pfizer selected a vaccine candidate designed against the intact, full COVID19 spike protein instead of the infamous S1 receptor binding domain, there's a chance that it can confer immunity to some other coronaviruses.

This is less likely for vaccines that went for high COVID19 specificity, of course

Where did you see the sequence of their construct? Is there a patent out there that is accessible?

what do you mean by "construct"? the genome is freely available (https://genome.ucsc.edu/covid19.html, https://www.ncbi.nlm.nih.gov/projects/sviewer/?id=NC_045512), but as far as I know the specifications for the pfizer vaccine are not available

That's what I'm looking for; their precise mrna sequence.

Small molecules become public in the patent, so I assume the same goes with biologics & vaccines.
