Health Department moves to phone, email notification system for COVID vaccine waitlist From staff reports The Henderson County Department of Public Health is utilizing a phone and email notification system for remaining individuals on its COVID-19 vaccine waitlist, which gives individuals the option to schedule an appointment or be removed from the waitlist. The Health Department is using the One Call Now system to notify individuals via phone, email and text who are next in line for appointments.
