  • You can't choose which vaccine you'd like to receive

You can preregister again if you need to update your information. For example if a medical condition now makes you eligible.

Even if you preregister, you can continue to look for appointments at pharmacies, health care providers, or other locations on VaxFinder.mass.gov.

Opting out of the preregistration list

If you find an appointment elsewhere, you can unsubscribe to the preregistration system.

  • Email: Click on the unsubscribe link in any of the email communications to remove yourself and anyone else using the same email address from the preregistration list
    • If you unsubscribe but change your mind, you'll have to preregister again
  • Text: Reply "STOP" to any of the text notifications to remove yourself from the preregistration list
    • Reply "START" to any of the text notifications to get back on the preregistration list

Confirmation

When you preregister, you will receive an onscreen confirmation with a Registration ID. You'll also receive either a phone call, text, or email confirmation, depending upon the preferred contact method you selected when you preregistered.

  • If you received a confirmation email, text, or call, your preregistration was successful
  • If you chose email and don't see the email right away, please check your email spam folder before thinking about preregistering a second time
  • If that doesn't work, then preregister again 

Email confirmations

The email is sent from no-reply@VaccineSignUp.mass.gov.

  • If you can't find it in your inbox, search your spam or junk folders
  • For Gmail users, it may get filtered into the “Promotions” category or tab

Phone/text confirmations

Text messages and phone calls will come from  (833) 313-1203. It should show as “Mass Gov” on caller/emailer ID for phone calls on most carriers.

  • If you didn't receive a text, make sure you entered a cellphone number and not a landline

Choosing a location

When an appointment is available for you, you’ll receive a notification with a booking link. Use this link to choose and schedule your appointment:

  • You’ll be able to choose from all the locations with available appointments
  • Select a location and click on the “book” link to go to the provider site to schedule the appointment
  • If you do nothing with your scheduling link, it will expire after 24 hours. You'll remain preregistered and will get another chance to book an appointment. Due to limited federal supply, it may take several weeks to get another appointment.

Appointment scheduling

After you're notified that an appointment is available, you have 24 hours to use your booking link to schedule your appointment. 

If you chose phone as your communication method, you'll receive a phone message with your Registration ID. Write down the Registration ID, call 211, and select Option 1 to talk to an operator to schedule your appointment.

  • It may take several weeks to be notified an appointment is available due to high demand and a limited supply of vaccine from the federal government.
  • If you miss the 24 hour window to book your appointment, you'll remain preregistered and will get another chance to book an appointment.

The booking link is for one-time use. However, it's only marked "used" once you schedule your appointment. So, if you open the link on your phone, and then decide you want to use your computer, you will be able to reopen the scheduling link on your computer to book your appointment.

Canceling or rescheduling your appointment

  • You can cancel your appointment through the confirmation email you receive from the vaccination location, not VaccineSignUp.mass.gov
  • You can also reach out to the vaccination location directly by phone to cancel.
  • If you cancel your appointment but still want to get a vaccine at a mass vaccination or regional collaborative location, you will have to preregister again.
  • If you want to reschedule your appointment, you should reach out to the location directly. Rescheduling may not be possible because of limited appointment availability.
    • Fenway Park, Gillette Stadium, and Reggie Lewis Center: (888) 623-3830
    • Dartmouth, Danvers DoubleTree, and Springfield: (888) 702-9042
    • Natick Mall: (888) 990-6066

Caregiver or companion appointments

If you are accompanying a person age 75 or older to their vaccination appointment, you can make an appointment to also be vaccinated at the same location on the same day.

  • Only 1 caregiver is allowed to schedule an appointment with each person age 75 or older

How to schedule a caregiver appointment

  • If you are 75 or older and would like someone to go with you, preregister at VaccineSignUp.mass.gov to be notified when it's your turn to schedule an appointment.
  • Call 2-1-1 to book an appointment for yourself and your companion once you receive the notification that an appointment is available for you.
  • Caregivers will need to attest that they are accompanying a person age 75 or older to be vaccinated.

Second dose appointments

The preregistration system for mass vaccination locations is for first doses only. Second doses cannot be scheduled through the preregistration system.

You can schedule a second dose at a mass vaccination location if:

  • You were unable to schedule your second dose when you received your first dose at a mass vaccination location
  • You can't go back to another location where you received your first dose

The fastest way to book a second dose appointment is to call a mass vaccination location. You must make sure the location offers the same vaccine you received for your first dose. Otherwise, you won't be able to get the second dose.
