How to schedule and prepare for your appointment

You will not need copies of medical records or a note from your doctor or health care provider to confirm you are eligible for these groups.

At this time, individuals 16 and older with two or more of certain medical conditions are eligible to receive the vaccine beginning February 18. Because vaccine supply is very limited, it may take several weeks or more to schedule an appointment. 

When you are eligible:

Step 1: Find a location and book your appointment.

  • Individuals without access to the internet or who are unable to schedule their appointment online can call toll free 2-1-1 or (877) 211-6277 for assistance.

Step 2: Learn how to prepare for your appointment and what you need to bring with you.

You will never be asked for a credit card number to make an appointment.
