Our UHN programs and services are among the most advanced in the world. We have grouped our physicians, staff, services and resources into 10 medical programs to meet the needs of our patients and help us make the most of our resources.
University Health Network is a health care and medical research organization in Toronto, Ontario, Canada. The scope of research and complexity of cases at UHN has made us a national and international source for discovery, education and patient care.
Our 10 medical programs are spread across eight hospital sites – Princess Margaret, Toronto General, Toronto Rehab’s five sites, Toronto Western – as well as our education programs through the Michener Institute of Education at UHN. Learn more about the services, programs and amenities offered at each location.

Ways You Can Help
Being touched by illness affects us in different ways. Many people want to give back to the community and help others. At UHN, we welcome your contribution and offer different ways you can help so you can find one that suits you.
The Newsroom is the source for media looking for information about UHN or trying to connect with one of our experts for an interview. It’s also the place to find UHN media policies and catch up on our news stories, videos, media releases, podcasts and more.
NO! You will still need to wear a mask, maintain social distance, and wash your hands frequently even after being vaccinated. Everyone entering UHN will still be required to go through screening and wear a mask.
Although vaccination provides protection against symptomatic COVID-19 infection, we are not sure at this point if it prevents the individual from spreading the virus to other people. In fact, we must remain extra vigilant as infection rates are at record highs and wide vaccine rollout will take up to a year. Everyone – vaccinated or not – must continue to mask, practice physical distancing and maintain hand hygiene. Public health recommendations to isolate/quarantine in case of travel or recent exposure remain the same.
Yes, people who have had COVID-19 are still encouraged to get the vaccine. We don’t know how long natural immunity from a COVID-19 illness lasts so it is still important to get vaccinated if you have previously had COVID-19. Please speak with your primary care provider to get more information specific to your health status. It is best to get the vaccine to stay protected.
We do not yet have sufficient concrete data to understand how long immunity lasts after a COVID infection, or with a vaccine. In other types of infections, we’ve seen that sometimes natural immunity doesn’t last as long as vaccine-induced immunity. But given the scale and urgency of the pandemic, we continue to recommend that people get the vaccine, in case your immunity from natural infection isn’t as long-lasting – and we can extend that immunity period by vaccinating.
The COVID-19 vaccine is indicated for active immunization to prevent symptomatic coronavirus infection (COVID-19). At this moment, we are using the Pfizer and Moderna vaccines at UHN clinics.
The Pfizer and Moderna vaccines are given as a 2-dose vaccine series. This means you must have two doses of the vaccine. As of March 5, 2021, the Province of Ontario has made the decision to extend the interval between 1st and 2nd doses up to 4 months, or 112 days, for most groups. This has been done to ensure that many more people are vaccinated in the province with the supplies that are received.
There are concerns that some identified mutations can affect antibody response to the virus, rendering the current vaccine less effective. However, it is unlikely that the vaccine will be entirely ineffective against these variants. Thankfully, we have a starting point of over 94% efficacy with the vaccines we’re currently using at UHN (Pfizer and Moderna) in preventing symptomatic infections. Another important piece of good news is that with mRNA technology, new vaccines tailored to mutations can be developed rapidly.
Although clinical trials were done with a shorter interval, several research and regulatory bodies are exploring vaccine efficacy with an extended interval. For further information, please refer to the National Advisory Committee on Immunization (NACI) Recommendations on the use of COVID-19 Vaccine. UHN strongly encourages recipients to still get their second doses when they become available, as even with an extended interval, you would be provided with extra protection against COVID-19 infection.
No, none of the vaccines approved in Canada can give you COVID-19 or any other illness. Keep in mind, it takes a few weeks for your body to build immunity after getting the vaccination. As a result, it's possible you could become infected with the COVID-19 virus just before or after being vaccinated, but the illness is not a result of the vaccine.
No. The COVID-19 vaccines do not contain mercury, formaldehyde, aluminum or fetal cells.

Most people who receive vaccines have minimal or no side effects, although, as with any medicine, adverse reactions can occur. The most common side effects are injection site pain, swelling, redness; headache; stomach and digestive complaints (e.g., nausea, vomiting, diarrhea and/or stomach pain); muscle or joint pain; tiredness; headache and chills/fever.
Should you develop any of the following symptoms or allergic reactions, seek medical attention right away. Symptoms of an allergic reaction or severe side effects include:
Please report any side effects or severe vaccine reaction to your physician or local health public health unit. If you experience a severe allergic reaction, call 911 or go to the nearest hospital.
You should talk to your primary health provider about known side effects from the vaccine vs. serious adverse reactions.
For TeamUHN and hospital collaborative health care workers:
Any post-vaccine symptoms that are the same as COVID symptoms require employees to follow hospital policies for reporting COVID symptoms. Please check with your organization and follow the appropriate processes. For TeamUHN, find our
reporting COVID symptoms process on the Intranet.
(Corporate Intranet > COVID-19 Updates > Health and Safety > Health Services COVID-19 Screening for Staff)
Yes. If you are experiencing any side effects such as fever, headache, chills or fatigue, you should remain off work and go to an assessment centre for testing. Please
click here to find a testing centre near you.
If you have a vaccine scheduled for less than 7 days before your surgery, you may want to reschedule your vaccine. Up to 15 people out of 100 may get a fever after getting a COVID-19 vaccine. If you have a fever on the day of your surgery, your surgery may be rescheduled.
Wait at least 1 week after your surgery before receiving a vaccine. Having a fever can be a sign of infection after surgery. By waiting 1 week to get the vaccine after surgery, your health care team will be able to determine if the fever is related to an infection and not a vaccine side effect.
We don't have data on these populations since they were excluded from the trials. However, expert groups have judged that for the large majority of people the benefits of the vaccine currently far outweigh any possible risks. As per the latest
Ministry of Health guidance, individuals who are pregnant, breastfeeding, or immunosuppressed may be eligible to get vaccinated.
Please note, we cannot provide medical assessments at our vaccination clinics. Questions about personal health must be reviewed with your health care provider before you arrive for your appointment.
Individuals who are pregnant — you will be asked be asked to provide verbal confirmation that you have consulted your health care provider when you arrive at the clinic.
Individuals who are breastfeeding — COVID-19 mRNA vaccines are not live vaccines and, based on their biologic mechanism of action, mRNA vaccines are not thought to be a risk to the breastfeeding infant. You will be asked to provide verbal confirmation that you are aware of the insufficiency of evidence for the use of COVID-19 vaccine in the breastfeeding population.
Individuals with autoimmune conditions, immunodeficiency conditions or those immunosuppressed due to disease/treatment that are receiving stem cell therapy, CAR-T therapy, chemotherapy, immune checkpoint inhibitors, monoclonal antibodies (e.g., rituximab) and other targeted agents (e.g., CD4/6 inhibitors, PARP inhibitors etc.) — you will be asked to provide verbal confirmation that you have consulted your treating provider when you arrive at the clinic.
All other individuals with autoimmune conditions, immunodeficiency conditions or those immunosuppressed due to disease/treatment — you are advised to have a conversation with your health care provider about the risks vs. benefits of taking the vaccine, but are not required to do so.

This compound is commonly used in laxatives, makeup, skin care products, personal lubricants and toothpastes. It is also in cough syrup, and in some food and drinks. PEG is in the COVID-19 vaccines we offer and it has been associated with some allergic reactions from the vaccines. If you are unsure of the ingredients you are allergic to, talk to a health care provider. Please note, we cannot provide medical assessments at our vaccination clinics. Questions about personal health must be reviewed with your health care provider before you arrive for your appointment.

Mild to moderate side effects are common within the first 48 hours of receiving either dose of the COVID-19 vaccine. If you’re experiencing any side effects that are also considered COVID-19 symptoms, you should self-isolate and contact your organization Occupational Health or Health Services department.
Members from TeamUHN are encouraged to access UHN’s Health Services information tool about vaccine side effects with more details. Please take the time to read the document
What to Expect After Receiving the COVID Vaccine, available on UHN’s COVID-19 Preparedness intranet page
(Corporate Intranet > COVID-19 Preparedness > Vaccine Information).
As directed by Ontario's Chief Medical of Health, second doses for hospital health care workers are being scheduled up to four months after the first dose. This is a government decision while managing supply chain issues—not UHN's. For more information, please read the full
Ministry of Health announcement.
The Science Behind Vaccine Dose Intervals: Answering Health Care Worker QuestionsFeaturing Dr. Brad Wouters, UHN's Executive Vice-President of Science and Research*Second-dose interval has since been extended to four months, as directed by the Ministry of Health and under guidance from the National Advisory Committee on Immunization (NACI). Otherwise, the content in this video is still accurate.
You will receive an email with the new date for your appointment. Please check your inbox — including spam folder – regularly.
As we receive more supply, we will continue to prioritize health care workers (clinical, non-clinical, support staff, research, learners) at UHN and from our hospital collaborative in high-risk areas,
working a majority of their hours in areas with COVID+ patient interaction.
UHN has opened a Vaccine Registry which is helping us understand the demand for vaccines within each
prioritization group (A-E) . This system will help identify who should be vaccinated first as supply becomes available. Please check the
TeamUHN Vaccine Registry tab on this FAQ page for more details.
Each hospital has adopted similar principles while managing their own prioritization groupings. If you work in one of the peer hospitals, please check what is the current system within your organization and register with only one hospital site.
There are checkpoints in place at our clinics to confirm people arriving for their appointments work in one of the hospitals from our collaborative (or are part of our eligible patient groupings). Audits may be completed if there is a concern about inappropriate bookings.
If you are returning to work within 4 months and are in Groups A-D (working on-site), please speak with your manager about being enrolled to receive your vaccine. If your anticipated return to work is longer than four months, please wait until you're within the four-month window.
Scheduling links are sent by email to eligible individuals as appointments become available. Once you successfully book your appointment, you will receive a confirmation email with instructions on how to get to the clinic and what to bring with you. You will be asked to present your booking confirmation email, hospital and government ID upon arrival at our clinics.
Links are sent to prioritized groups and must not be forwarded or shared.
If you don't receive a confirmation email, you don't have an appointment.
Your link may have expired.
For TeamUHN: Links expire after 24 hours. If you don't book an appointment within that timeframe, your link will expire and you will be removed from the UHN Vaccine Registry. If you are still interested in receiving the vaccine, you will need to register again through the link posted on the
Intranet(Corporate Intranet > COVID-19 Preparedness page > Vaccine Information).
For hospital collaborative: Please contact whoever sent you the link to check expiration timeline and re-registration process.
No. We are using a provincial system, which means your organization is not automatically updated. Please check with your organization for the current procedure to inform Occupational Health that you have been vaccinated. If you have received the COVID-19 vaccine
anywhere, please contact the Health Services/Occupational Health department at the hospital where you work most of your hours to ensure they are notified. You must provide notification
after each dose.

The information below applies to TeamUHN only. If you work at one of our peer hospitals, please check with your organization for information on their current registration system.
Maintenance Downtime — the TeamUHN Vaccine Registry will undergo scheduled maintenance every 2 weeks, from 4:00-5:00pm. The registry will not be available during this time. Upcoming downtime: June 30, July 14, July 28
If you’ve already received your first dose, do NOT use the Registry to attempt to book or indicate that you need your 2nd dose. Your 2nd dose scheduling is already in the sytem (even if it's rescheduled). We still encourage you use the Registry to inform us if you have been vaccinated, as this helps us understand our vaccination rate in specific areas.
At UHN, we are launching a Vaccine Registry which will help us understand the demand for vaccines within each
prioritization group (A-E) . When registering, you will be asked to complete an attestation verifying you are a member of TeamUHN, your position and your group. This system will help identify who should be vaccinated first as supply becomes available.
Yes. Aside from your group, the registration system will also ask if you’re above 60 years old, if you work performing aerosol generating medical procedures, and if you work most of your hours interacting with immunosuppressed patients. All of this will be taken into account when prioritizing vaccination.
We have created the registry to understand the demand across different units and sites at UHN. If you do not wish to get vaccinated or are undecided, that information will not be shared with your manager. Managers may be contacted to confirm individuals’ selected prioritization groups for those who have registered.
Please consider your current role, as we want to identify and prioritize people who are currently at a higher risk of exposure to COVID-19. You will be able to update your registration status if your role changes.
Yes. If you change your mind about your vaccine preference, you will be able to submit an updated response with your latest intention. The system will refer to the most recent response submitted.
Yes. If your role changes, putting you at higher or lower risk group than previously stated, you will be able to update your group within the system.
No. At this moment, the registry is only open to members of TeamUHN – staff in clinical and non-clinical roles, researchers and learners.
This registry is optimized for Internet Explorer 11, Edge, and latest versions of Chrome, Firefox, Chrome on Android, and Safari on iOS.
Due to anticipated high volumes, the registry may not load during your first attempt. Please wait 20 minutes and try again. If you encounter any technical issues, please contact the Help Desk – call extension 4357 (HELP) from any UHN phone, or by calling your site main line and entering 4357 (HELP) or email

You will be contacted with information about your first appointment.
Please bring the following to your appointment. Not all of these items may be needed for your appointment. Our clinic or your referring doctor will let you know what you must bring.
Please arrive 15 minutes before your appointment.
When you arrive, you will sign in with the receptionist. You will need your health card (OHIP card) to sign-in. If you do not have an OHIP card, please bring another form of government-issued photo ID, such as a driver’s license or passport.
You may be given a Measuring Health Equity Questionnaire to fill out. This form contains questions about your background. We collect this information to find out who we serve and what unique needs you may have. The form is voluntary and you can choose ‘prefer not to answer’ to any or all questions. However, the information you choose to give us will help us improve the quality of care for you and others.
First appointments take longer than follow-up appointments. Your first appointment can take 2 hours or more. Follow-up appointments usually take 15 to 30 minutes. We do everything we can to stay on time but sometimes unforeseen circumstances may delay your appointment.
At the end of your first appointment, the nurse or doctor will give you a contact list for your health care team. If you don’t get a contact list, feel free to ask for it.
After every appointment, a member of your health care team will tell you about your next visit. Be sure you understand what is going to happen next. For example, know the time and place of your next visit or if someone will call you with this information.
If you are unsure about what your next steps are, don’t be afraid to ask a member of your team. We are here to help you.
We understand that reaching us by phone can sometimes be difficult. Often our phone lines are busy or are turned over to the message centre so our staff can prepare for clinic visits or help other patients. We make every effort to return your call within 24 hours.
