COVID-19 vaccine doses administered in Ottawa has surpassed the city’s stated inventory amid efforts to extract a sixth dose from each vial, according to the local public health unit.Ottawa Public Health’s COVID-19 dashboard shows 26,337 doses of the Pfizer-BioNTech vaccine have now been administered as of Monday.That surpasses the stated number of 25,350 doses so far received in Ottawa.
The city’s inventory estimates are based on an expectation that only five doses are extracted from each vial of the vaccine Ottawa has received.The discrepancy in figures is accounted for through the occasional successful extraction of a sixth dose, OPH says in a note on its dashboard.While standard syringes can reliably draw five doses from Pfizer’s.
