Step 1: Preregister for a mass vaccination or regional collaborative location, or find a location and schedule your appointment

There are different ways to find a vaccine appointment:

Massachusetts’ preregistration system makes it easier to request and schedule an appointment. People can preregister for a COVID-19 vaccine appointment at mass vaccination locations and certain regional collaborative locations only. More locations will continue to be added.

Once you sign up for preregistration, you’ll receive weekly status updates. You can opt out at any time if you find an appointment elsewhere. Once an appointment is available, you’ll be contacted with the opportunity to book the appointment and have 24 hours to accept it.

Massachusetts receives a limited supply of COVID-19 vaccine doses from the federal government each week. Due to high demand and very limited supply, it may take several weeks to schedule an appointment or to be notified that an appointment is available.

Individuals without access to the internet or who are unable to schedule or preregister for 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.
