from 7 different suppliers. The problem has been delivery. Our over 75's have been vaccinated with Pfizer or Moderna (including all long-term care residents, first responders, medical workers etc.) and just this week those of us 70-75 have been able to book. My appointment is next week. But we've extended the second dose to 4 months. Not what was advised but knowing the first vaccination appears to greatly reduce chances of infection, that's what the government decided.
But the Astra Zeneca vaccine (and Biden leant us 1.5M doses) was about to be available to all adults until worries about severe blood-clotting events came out.
Meanwhile over 12M in the UK have had their second AZ vaccination, and no problems there.
Years, ago there was a huge and very successful lab in Toronto (Connaught Labs attached to University of Toronto, where Drs. Banting and Best discovered insulin and changed diabetics' lives forever). A Conservative Prime Minister decided Canada didn't need that lab and arranged for it to be sold to U.S.' big pharma.
Bad things happen when conservatives are in power. Another example was the Avro Arrow, the first supersonic airplane which would have made Canada one of the world's leading aircraft manufacturers. All the talent was right there. But the Conservative Prime Minister said it cost too much money.
Conservatives never look forward, they only look back, more's the pity.
BTW, all those unused doses Canada ordered will be going to third world countries. That is, if they're ever delivered to us...
