I went to CVS’s vaccine site to register, thinking they might have an announcement or a timeline or something, but the page made it sound like they already had the newest booster available, so I signed up for Saturday (tmrw) and got a slot. Earlier today though, I got a message saying my appt was canceled bc they didn’t have the newest booster yet. Kind of annoying. I knew it seemed too soon, but it was their language that prompted me to schedule.
