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. Because vaccine supply is very limited, it may take several weeks or more to schedule an appointment. 

Individuals age 16-17 should only receive the Pfizer vaccine at this time. Read more about vaccine safety.
