The text message informed me that I didn't have time to get a booster shot.

Yes, some places have already opened SMS reminders. Please contact CDC if SMS reminder has not been turned on. Once they turn on the SMS reminder, they can wait for SMS to get vaccinated. If not, vaccinate according to the time of the appointment notice.

According to the introduction of the Immunization Planning Section of CDC, starting from 10, CDC will input the phone number of each parent who has reserved information into the SMS platform. Every month, the center will send a warm reminder to parents through the SMS platform. In addition to reminding parents to take their children to vaccinate on time, it also sends vaccination knowledge to parents regularly.

The CDC reminds parents that if the mobile phone number changes, they should go to the center to update it in time.
