I don't think this was mentioned here before...

As you know, the interval between the Pfizer doses is 21 days, while the interval between the Moderna doses is 28 days.  

The question is, what if you don't get your 2nd dose on the appointed day?

OWS's Dr. Slaoui indicated that normally, the longer time between two doses, the better the effectiveness.  However, the longer the time between them, the more likely that you might get the illness in that time.

So, if you are quarantining (for exposure, vs isolating for having COVID) when your 21 days is due for a 2nd Pfizer shot, my understanding is you probably are fine to wait until you can safely get your 2nd shot.     (Always, talk to your physician for health advice)

I have not heard any official position on what to do about the 2nd dose if you get COVID after the 1st shot but before the 2nd shot.  I expect that was covered in the FDA approval, and I'm sure your health agency will know what to do and will advise you.
