The Yukon government continues to improvise its vaccine rollout strategy in the face of an uncertain supply. At the government’s weekly COVID-19 briefing held Wednesday afternoon, Premier Sandy Silver and Dr. Brendan Hanley, the chief medical officer of health, said they were confident the territory could meet its goal of inoculating 75 per cent of the adult population willing to accept the vaccine by March or April. A certain amount of flexibility has to be incorporated into the process, both said, because the federal government, which controls the supply, isn’t providing guaranteed fixed delivery schedules. That’s not what Silver said the territory had arranged in December.
