If you received your first dose of Pfizer, Moderna or AstraZeneca COVID-19 vaccine, you will need a second dose to be fully protected.
In Ontario, the second dose for these vaccines is now given up 112 days after the first dose.
This timing affects everyone in Ontario, except for high-risk individuals, including:
- Residents of long-term care homes/retirement homes/elder care lodges/assisted living facilities.
- Adults who are First Nations, Inuit and Metis
- Highest-risk health care workers
- Individuals with certain medical conditions:
- Transplant recipients (including solid organ transplants and hematopoietic stem cell transplants)
- Individuals with malignant hematologic disorders and non-hematologic malignant solid tumors receiving active treatment (chemotherapy, targeted therapies, immunotherapy), excluding individuals receiving solely hormonal therapy or radiation therapy
- Individuals on dialysis
The Province of Ontario may add to this list from time to time, but no other exceptions are allowed unless the government adds to this list.
If you are eligible for a shortened dose interval and are not able to book an appointment through your health care provider or pharmacy, follow the instructions to be added to the Click and Connect system and be placed on a booking list for a second dose appointment.
If you booked your first dose of vaccine through the provincial booking system, you will have already received an appointment for your second dose. If you need to change your appointment, please call the provincial booking system booking number: 1-888-999-6488.
