Did you consider wearing an N95 and washing hands thoroughly upon departure
Not OP, but if the main attraction of the “holiday event” is a meal, it’s not like you can wear an N95 mask to eat. I suppose it’d be an option to make a quick appearance and then bow out before the meal, but it sounds like OP’s family’s would just be assholes to OP if OP showed up just to leave early (and was also assholes when OP declined to show up entirely.)



























Some vaccines don’t really guarantee anything beyond reducing your chance of ending up in a hospital (and they can be less good even at that if the particular strain that you get isn’t the one you were vaccinated for.) For some vaccines, even vaccinated, you can still get the disease you’re vaccinated for and have anything from a couple weeks of being sick to life-long debilitating effects.
All else being equal, unless you have some particular reason why you’re not a good candidate for a particular vaccine, the significant majority of people are much better off vaccinated than unvaccinated, but vaccinated doesn’t necessarily mean safe to go lick doorknobs or, case in point, dine with a dozen relatives, whether those relatives are vaccinated or not. And of course there are plenty of reasons why OP might be at higher risk than most.
