About Second Doses of COVID-19 Vaccine

   

In general, your second dose should be scheduled through the provincial booking system or a pharmacy, unless you are eligible for a targeted clinic in our local booking system (such as workplace or immunocompromised/pregnancy).

Select primary care and pharmacies are offering COVID-19 vaccines. To find your closest pharmacy visit: COVID-19 pharmacy vaccine locations (ontario.ca)

 

If you booked your first appointment using the provincial booking system, a second dose appointment was booked automatically at that time. Please check your confirmation email for more details or call the Provincial Vaccine Information Line. You may book a new second dose appointment based on the accelerated rollout schedule and availability or choose to keep your existing appointment.

If you booked your first appointment in the local booking system, you may book a second dose based on the accelerated rollout through the provincial booking system.

Due to the accelerated rollout of second doses, individuals who are eiligble will be able to book their second dose appointment based on the timing of their first dose and as long as it at least 28 days or more since your first dose.

 

If you received a first dose of AstraZeneca vaccine, the second dose can be scheduled 8 to 12 weeks after the first, with informed consent. If you wish to receive an mRNA vaccine for a second dose you can book an appointment through the provincial booking system or a participating pharmacy. For individuals who wish to receive second dose of the AstraZeneca vaccine, individuals can contact the pharmacy or primary care provider where they received their first dose.

Accelerated Rollout of Second Doses 

On May 28th, 2021 the province announced an accelerated rollout of second doses for the COVID-19 vaccine. Individuals will be able to book their second dose appointment based on the timing of their first dose and as long as it at least 28 days or more since your first dose. The anticipated schedule is subject to change. On June 4, Ontario announced additional changes to the booking schedule: Ontario Expanding Accelerated Second Dose Booking to More Ontarians Ahead of Schedule | Ontario Newsroom and the latest changes were announced on on June 17th Accelerated Second Dose Eligibility Continues Ahead of Schedule | Ontario Newsroom

 

The following groups are eligible to book an appointment for an accelerated dose:

  • People aged 70 and over
  • People who received their first dose on or before April 18
  • People who received AstraZeneca at least 8 weeks after your first dose with informed consent.

As of May 11th, Ontario paused the administration of first doses of AstraZeneca Vaccine. Ontario Pauses Administration of AstraZeneca Vaccine | Ontario Newsroom

 

On May 21, Ontario announced that second dose administration of AstraZeneca is proceeding. Ontario Proceeding with Second Dose Administration of AstraZeneca | Ontario Newsroom.

 

On June 3, 2021 Ontario updated guidance for individuals who received the first dose of the AstraZeneca vaccine and who have not yet received their second dose, to allow for the mixing of COVID-19 vaccines if desired. This decision is in alignment with updated guidance from the National Advisory Committee on Immunization (NACI) recommendation. Ontario Updating AstraZeneca Second Dose Guidance | Ontario Newsroom Ontarians who have received their first dose of the AstraZeneca COVID-19 vaccine can choose to either receive a second dose of the AstraZeneca vaccine, or an mRNA (Pfizer or Moderna) vaccine for their second dose. Both second-dose options available to individuals who received their first dose of the AstraZeneca vaccine are safe and provide strong protection against COVID-19 and will count as a completed series.

 

On June 12th, 2021, Ontario accelerated the second dose interval for individuals who received their first dose of an AstraZeneca vaccine. With informed consent, individuals can choose between a second dose of AstraZeneca or an mRNA vaccine, at an eight to 12-week interval, recognizing that while waiting 12 weeks helps to ultimately provide more protection, some may choose to receive their second dose sooner to have the increased protection provided by a second dose earlier. All of these options provide protection against COVID-19, including the Delta variant, and have been deemed safe.

 

Individuals who wish to receive an mRNA vaccine for their second dose can book an appointment through the provincial booking system, through public health units that use their own booking system, or a participating pharmacy. For individuals who wish to receive second dose of the AstraZeneca vaccine, individuals can contact the pharmacy or primary care provider where they received their first dose.

 

Ontario Accelerates Second Doses of AstraZeneca COVID-19 Vaccine | Ontario Newsroom

 

If you has an AstraZeneca / COVISHIELD COVID-19 vaccine as your first dose, you have a choice about the type of vaccine you would like for your second dose. COVID-19 Vaccine Information for Individuals who received a first dose of the AstraZeneca/COVISHIELD COVID-19 vaccine (gov.on.ca).

 

NACI’s guidance advises that the Pfizer and Moderna COVID-19 vaccines can be safely interchanged for first and second doses if the original mRNA vaccine is not readily available. Ontarians who received a first dose of an mRNA vaccine should be offered the same mRNA vaccine for their second dose. If the same mRNA vaccine is not readily available, another mRNA vaccine can be offered instead to complete the vaccine series.
