From what we know about the Moderna and Pfizer vaccines, is it possible for SARS-CoV-2 to contain spike protein mutations that allow it to escape the vaccine-induced immune response, but still retain enough function to be infectious?

Do we know enough about the specific sequences targeted by these vaccines to say whether they are specific to highly conserved regions of the spike protein such that major mutations would lead to a non-functional spike protein?

There have been reports that some mutations in the Spike protein allow the virus to remain infectious and make the vaccines less effective. 

But it's not all or nothing. Less effective than 95% can still be very good.

It would be hard for the virus to mutate enough to completely and reliably evade our immunity from the vaccine or from prior covid infection. 

We are also already in vaccine clinical trials for some of the variants. 

All things considered, humanity is raining on COVID's parade. We are winning this race and we will win this race.
