I went to a party with 14 other vaccinated people; 11 of us got COVID

The official Centers for Disease Control and Prevention guideline stated that, since I was fully vaccinated, I didn’t need to do anything different unless I started developing symptoms. I’m an epidemiologist at a major medical research university, which has a dedicated COVID exposure hotline for staff. I called it, and workers said I didn’t need to do anything.

Then, I started to hear that a few other people who had been at the party were getting sick. Then a few more. At this point, 11 of the 15 have tested positive for COVID.

Fortunately, none of us seems to be seriously ill. When fully vaccinated people experience so-called “breakthrough” infection, they tend not to progress to serious disease requiring hospitalization, and I expect that will be the case for us. But I can tell you that even a “mild” case of COVID-19 is pretty miserable. I’ve had fever, chills and muscle aches, and I’ve been weak enough that I can barely get out of bed. I don’t wish this on anybody.
