Quite a few people with Paxlovid showing up with side effects. ( I haven't looked at the current rules, I don't know if isolation is required, but the general rule of the last two years applies. They will absolutely go vacationing while positive, then only show up at clinics, ER etc if they get nasty symptoms)
Then again, the effects are so varied, it's more like 'stop taking it and see if it goes away. If not, contact a dermathologist/gastrologist/whatever cuz it's probably not the Paxlovid'. I got it in spring, of course (after three doses, last in December), didn't use Paxlovid. Although, surprisingly, a colleague at the clinic did catch it again in June after having had it in Feb.
As far as I can say, I'm no medic, despite the wonderful privilege of witnessing most of the crap in the medical system, but it seems it's like 2 weeks ahead of my personal expectations. Like, I thought it would be surging by late July, it was already peaking like crazy in the week before the 14th. Probably a combination of new strain and higher viral load due to a basically full tourist season and lifting of restrictions
