We're back in quarantine--our son has COVID

My husband finally recovered from COVID, round 2 (his "Paxlovid rebound)" about a week and a half ago, so our son went to hang out with some friends over Superbowl Weekend--he came home yesterday, and tested positive for COVID tonight.  He called a local Urgent Care/medical drop-in center's 24-hour phone line and they sent a prescription for Paxlovid to our usual pharmacy, to be filled tomorrow.  I guess we're *not* going to synagogue in person this Shabbat.
