Got my booster a little over a week ago. My wife came down with something (after recently being boosted as well) and it took her out for a few days. She still worked remotely, but she felt terrible and I had to run and try to find soup and Gatorade, etc. Luckily I didn't manage to catch it or at least didn't become symptomatic. She still feels a bit tired and I'm guessing she probably got the Omi.
I'm really hoping that with the Omi tearing through and what seems to be like less severe symptoms for most that we might be on the endemic side of things soon with a reduced dangerous strain going forward.
