Mass General Brigham Patient Gateway - Your secure online health connection

Mass General Brigham is offering first dose appointments for the COVID-19 vaccine to patients who are eligible under the state’s current vaccine distribution plan. Please note that our location at Assembly Row in Somerville has the most appointments available. Appointments at our other locations may be more limited.

We contact patients through Patient Gateway, email, or text message to schedule appointments. We are scheduling all vaccine appointments through a central scheduling center. Please do not contact your doctor's office about vaccine appointments. It may take time before you receive your invitation and are able to schedule your appointment. Please be patient.

We are currently providing Pfizer and Moderna COVID-19 vaccines. Patients getting a first dose will receive either Pfizer or Moderna. We are primarily offering the Pfizer vaccine at our clinics. We are not able to offer patients a choice as to which first dose vaccine they receive. If you receive Pfizer or Moderna for your first dose, you will receive the same vaccine for your second dose.

We have paused administration of the Janssen Johnson & Johnson vaccine. The U.S. Centers for Disease Control and Prevention and the Food and Drug Administration jointly recommended that administration of the Johnson & Johnson vaccine be paused out of an abundance of caution while both entities review data involving six reported U.S. cases of a rare, severe type of blood clot out of the nearly 7 million people who received the vaccine. See our website for more information.
