THE CANADIAN PRESS/Carlos Osorio - POOL April 14, 2021 - 2:28 PM Ontario blamed a vaccine shortage in some areas on a delayed shipment Wednesday as Ottawa pledged to keep pumping out Oxford-AstraZeneca shots following a safety review that found the product's benefits far outweigh its rare risks. Some immunization clinics in Ontario were forced to close their doors or cancel appointments due to what Premier Doug Ford said was a thrice-delayed shipment of the Moderna shot. "We were expecting the shipments to come in, but unfortunately we never ended up getting them," Ford said. "...You can't plan properly if you don't know the flow of the product coming in through your production lines."
