TORONTO — The Ontario government is accelerating the vaccination of residents in long-term care, high-risk retirement, and First Nations elder care homes by a new target date of February 5, 2021. To protect access to second doses of the Pfizer-BioNTech vaccine for those who have already received their first dose, Ontario will maintain the maximum interval of 21-27 days for long-term care, retirement and First Nations elder care home resident groups and up to 42 days between the two doses for all other groups. These adjustments are being made following notification by the federal government of reductions in Pfizer-BioNTech vaccine shipments.
