I am 75 years old, have registered on the AZ covid-19 website, but am unable to schedule an appointment to receive the vaccine. For every date between 1/16/21 thru 2/5/21, I receive the message "There are currently no events available..." Why are no vaccination sites available within 50 miles of my home in Sierra Vista for the next 3 weeks? I am especially concerned because next Tuesday the state is making the vaccine available to even more people, and I may be forced to wait months to find an available appointment.
