Text from this number pretending to be "USCF Health" says to call 415-909-5754 "to complete a short survey so we can schedule your appointment" for a COVID booster. Definitely not UCSF.

Scammers taking advantage of COVID fears by hoping you'll think it's your doctor's office or insurance — in the same vein as those "your car warranty is ending" calls having nothing to do with your car's actual manufacturer or your actual warranty.

Left voicemail saying they called from "UCS" with a message (ID: 3030X) about "your booster ****" and to press "1" to hear that message. Said they would try again later. Highly suspicious.

This number 4159219855 called me yesterday when I was driving. Then it called me again in the morning but I was at work and couldn't answer it. I was trying to call back several times but the line was engaged. I'm sure they will call me again but I feel it's a telemarketer or a scammer.
