UHN continues to follow the Government of Ontario guidelines for shortened interval 2nd-dose vaccinations. As of June 14, if you had your 1st Pfizer/Moderna dose on May 9 or earlier, you are now eligible for a 2nd-dose. If you have a second dose booked at a UHN clinic, please check your email for a new appointment date and clinic location. If you do not have an email address, we will call you. If you do not hear from UHN, you will need to reschedule your second dose directly through the Ministry of Health. Visit the Ontario booking website or call 1-833-943-3900 to change your second dose appointment.

About UHN Vaccination Clinics

UHN is one of Ontario's sites that have been designated to receive and administer COVID-19 vaccines to priority populations. Eligibility criteria has been set by the government of Ontario and is being provided on a priority basis.

Vaccine Eligibility

The Government of Ontario and City of Toronto are deciding how the vaccine is being distributed. UHN is following the Government's decision when distributing the vaccine to staff and patients. With Ontario's expanded eligibility for vaccinations, we will now be moving registration for all Indigenous Adults, Home Care recipients, Faith Leaders, High Risk Chronic Conditions groups, and priority postal codes to the province's centralized booking system. Anyone who has already registered with UHN and is awaiting a first dose appointment will still be contacted by UHN or the Ministry of Health when an appointment is available. Eligible patients can now register through the provincial booking system or call the Provincial Vaccine Information Line at 1 888 999 6488 (TTY 1 866 797 0007).

The following groups have been prioritized to receive their vaccination at UHN:

At this time, we are not booking any other groups. Priority groups for receiving the vaccine are designated by the Province of Ontario and will be shared by the Ministry of Health.

Booking Information

Eligible priority groups can use the UHN vaccine registry, and will be sent a booking link when slots become available. TeamUHN and health care workers in the hospital collaborative should continue to check their emails for registration links when they become eligible. Please do not call the hospital to inquire about an appointment.

The UHN vaccine clinics are not accepting any walk-ins. Anyone who arrives without a pre-scheduled appointment and confirmed time will be turned away.

Important Supply Note

Vaccinations are subject to supply availability and shipment. If there are any changes to your appointment, we will let you know.
