After a sneak peek at their results last week, Pfizer and BioNTech are now finished testing of their vaccine. Results say it's 95 per cent effective with no serious safety concerns. A few other notable things 👇thestar.com/news/canada/20…
The size of the trial: People have asked about the speed which which these vaccines are being made. It is fast! But mostly because there's tons of money/support, not because testing isn't happening. Pfizer so far has trialed 43,661 volunteers at 151 sites in 6 countries.
Seniors: your immune system ages as you do, and seniors often need specially made vaccines. Experts have worried these first doses might not work for those who need them most. But Pfizer says their data shows 94% efficacy in those over 65. thestar.com/news/canada/20…
The cold chain problem: the new technology both Pfizer and Moderna are using has raised questions about refrigeration. Pfizer's has to be stored at -70 but they said today they've created special shipping containers that use dry ice to keep the vaccine stable. 
What's next: Okay, Canadian pals, you're going to start hearing about emergency use authorizations. That is, so far, an American thing. Here, Health Canada will decide if it will be approved. That process has already begun, so stay tuned. thestar.com/news/canada/20…
