Those waiting for a COVID-19 vaccine might be getting one sooner than expected, just in time for Christmas.

Vaccinators received an unexpected and welcome surprise after their vials meant to vaccinate five people actually treats six people.

"The amount of any excess vaccine left in the vial can vary based on provider technique and ancillary supplies. There may be an excess vaccine in the vial after the withdrawal of 5 doses, which in some cases may leave enough volume for an additional dose," Christina Antoniou, Director of Corporate Affairs, Pfizer Canada says in an email to CHVN.

Instead of vaccinating 900 more Manitobans at one time, the province discovered they have the capability to vaccine 1,300.

The province is continuing to book appointments for specific healthcare workers. They have booked more than 1,200 appointments so far.

Those eligible includes:

• work in critical care units, born on or before Dec. 31, 1980;
• work in long-term care facilities, born on or before Dec. 31, 1962;
• work in acute care facilities, born on or before Dec. 31, 1960; or
• be assigned to COVID-19 immunization clinics.

Later in the week, more eligibility criteria will be revealed. Upcoming clinic dates and the next phases of the COVID-19 immunization campaign are also set to be shared with the public.
