Ontario Expanding Accelerated Second Dose Booking to More Ontarians Ahead of Schedule
June 07, 2021

TORONTO — Due to an increasing supply of vaccines, the province is inviting individuals aged 70 and over as well as individuals who received their first dose of an mRNA vaccine (Pfizer or Moderna) on or before April 18, 2021, to book an accelerated second dose appointment ahead of schedule.

Ontario expects to receive approximately 4.7 million doses of the Pfizer COVID-19 vaccine in June and approximately 3.54 million doses in July. The province has also received 193,000 doses of the Moderna vaccine. This reliable and increased supply of vaccines has allowed the province to rapidly expand access to vaccines in all public health units and through various channels, including mass immunization clinics, hospital clinics, pharmacies and primary care settings, providing convenient access across Ontario.

As of 8:00 a.m. on Monday, June 7, 2021, individuals turning ages 70 and over in 2021, as well as individuals who received their first dose of an mRNA vaccine on or before April 18, 2021, will be eligible to schedule an appointment to receive their second dose of a COVID-19 vaccine at a mass immunization clinic through the provincial booking system and call centre. Some public health units using their own booking system may expand eligibility sooner.

Beginning on June 4, 2021, these groups are eligible to receive their accelerated second dose appointment through pharmacies and primary care settings participating in the vaccine rollout. In addition, individuals who received their first dose of the AstraZeneca vaccine and are opting to receive either a second dose of AstraZeneca or a mRNA vaccine can now schedule their second dose appointment at a participating pharmacy. There are now 327 pharmacies in the Toronto, Windsor-Essex and Kingston, Frontenac, Lennox & Addington public health units offering the AstraZeneca vaccine, and nearly 450 additional pharmacies offering the Moderna vaccine.

The province will continue to accelerate second doses for all Ontarians based on when they received their first dose, as well as on the availability of vaccines. All Ontarians are encouraged to get vaccinated as soon as they can, and to receive their second dose as soon as they are eligible to ensure maximum protection against COVID-19.
