Since I now personally know at least 7 of the cases from Provincetown, I figured I'd chine in. All of my friends were vaccinated. All are in the 30-45 age category. All had mild-to-moderate symptoms (more on that "moderate" bit in a moment). A couple venues in town required proof of vaccination for entry. Masks were mostly non-existent, though at the time that was the state and CDC guidance.
One friend is a nurse who works in clinical research. Here's what he had to say (which he posted in a public post on FB):
"1. I traveled to Provincetown with the understanding that vaccinated people were at a low risk of contracting Covid because that is what the science at the time was saying and therefore do not regret my decision to attend bear week and think any shaming of people who made this decision is counterproductive and gross.
2. The science has shifted as it tends to based on new data and while I wasn't aware I was engaging in a real life experiment at the time, I am glad what happened in Provincetown is in part guiding the new CDC recommendations.
3. While I'm extremely relieved my breakthrough infection of Covid wasn't severe and did not result in hospitalization, I want to stress for me it was extremely unpleasant. My symptoms included intermittent fever, night sweats, chills, sore throat, cough, diarrhea, dizziness, tachycardia, elevated blood pressure, nausea, nightmares, anxiety, all over body aches, extreme fatigue, disorientation, brain fog (still ongoing). Basically it super sucked and isn't something I'd recommend to anyone which brings me to.....
4. If you have not gotten vaccinated, now is the time. Please. Unless we reach a point where nearly everyone who is eligible receives a vaccine, new variants will keep popping up and breakthrough infections will become more frequent."
