I had an appointment for the COVID vaccine tomorrow. However today I was around a bunch of family members. None of them had COVID (unless they just didn't experience symptoms yet). So I have no idea if I'm infected or what. Can/should I still get the vaccine? Do I have to wait and get tested first? If it's only been a day, do I even have COVID yet? I just don't know how this works and some of the websites are very vague.
