The province’s top doctor has once again revised the timing of when people can get the second dose of the COVID-19 vaccine.
In a memo sent to hospital CEOs and Medical Officers of Health on Wednesday, Ontario’s Chief Medical Officer of Health Dr. David Williams has recommended extending the dosing interval for the second shot of the Pfizer-BioNtech vaccine to 35 days and no more than 42 days.
Previously, the province sent out guidance that the second shot be given anytime between 21 and 42 days after the first dose was administered.
The recommendation applies to everyone outside of long-term care settings, essential caregivers and staff, and First Nations elder care homes, where the second doses are set to be administered between 21 and 27 days later.
“We recognize that this allocation reduction will have significant impact on the current level of vaccine delivery across the province,” Williams said in the memo.
“The extended dosage interval is a direct response to the temporarily reduced vaccine availability from the federal government and uncertainty regarding the stability of supply in the near-term.”
Williams points out that there are no scheduled deliveries of the Pfizer-BioNtech vaccine this week and just over 26,000 doses expected the first week of February. The province says it has yet to receive information on how many doses are to be delivered for the weeks of Feb. 8 and 15th.
Pfizer has advised Canada, and other countries, that delivery of its COVID-19 vaccine would be impacted for several weeks due to work to expand its European manufacturing facility.
