Sonoma County recently has launched a standby list for coronavirus vaccination appointments.

Residents who register for the list will be notified when vaccination appointments at local clinics become available because of extra doses or unfilled appointments, said Matt Brown, a county spokesman.

Individuals will be called in the order that they registered, Brown said, and should be “ready to go” once they are notified. The calls may come from a blocked number.
