New York State will distribute the vaccine in phases based on need and risk. The State also develops the program for distribution and authorizes the vaccination sites. The Westchester County Center and the state “pop up” locations are not listed as they are state run. Prior to setting up an appointment, you should determine your eligibility for the vaccination. Remember that an appointment is required. If you visit a location without an appointment, you will not receive a vaccination. Find answers to general vaccination questions.
