With a majority of Ontario adults having received a first dose of the COVID-19 vaccine and over three million doses of the Moderna vaccine arriving in June, the province is continuing to accelerate its vaccine rollout by expanding eligibility for second doses ahead of schedule.
- As of Monday, June 21, 2021 at 8:00 a.m., all Ontarians who received their first dose of an mRNA COVID-19 vaccine on or before May 9, 2021 will be eligible to book or rebook their second dose appointment at a shortened interval.
- As of Wednesday, June 23, 2021 at 8:00 a.m., individuals who received their first dose of an mRNA vaccine on or before May 30, 2021 and who live in the catchment area of one of the 10 public health units identified as Delta hot spots (Durham, Halton, Hamilton, Peel, Porcupine, Simcoe-Muskoka, Toronto, Waterloo, Wellington-Dufferin-Guelph, and York public health units) will be eligible to book or rebook their second dose appointment at a shortened interval.
- Starting the week of June 28, 2021 (days / sequence to be confirmed) all Ontarians aged 18 and over who have received their first dose of an mRNA COVID-19 vaccine will be eligible to book their second dose appointment. The appointment will be scheduled at least 28 days after the first dose, per the recommended interval.
In addition, effective June 14, 2021, individuals who received their first dose of the AstraZeneca vaccine are also eligible to receive a second dose of a COVID-19 vaccine at an interval of eight to 12 weeks, with informed consent. This can include a second dose of AstraZeneca or an mRNA vaccine.
Ontario’s allocation of the Pfizer COVID-19 vaccine meant to arrive during the first two weeks of July will be lower than initially projected (decreased from approximately 885,000 to 348,000 doses) and is planned to catch up during the last two weeks of July. The government will adjust and mitigate any impacts of this decrease to the provincial vaccine rollout.
The province will continue to expand eligibility for accelerated second doses across Ontario as additional vaccine allocations and shipment timelines are confirmed by the federal government.
Individuals who are eligible to receive an accelerated second dose are invited to schedule their appointment through the provincial booking system directly through public health units that use their own booking system, and through participating pharmacies. Select primary care providers will also be reaching out to book appointments.
