There are a few things.
I do think it's really important that we appreciate how incomplete and tenuous the U.K. data is on AstraZeneca safety. Their MHRA, which reports on their Yellow Card system for vaccine safety, reported again last night our time, or early this morning, and the risk is now for AstraZeneca and VITT is one in 76,000, so it's been progressively increasing in frequency for first doses.
They're really early in their rollout for second doses, and I don't have much confidence in really understanding the risk to Canadians of a second-dose VITT from the AstraZeneca vaccine. It may turn out to be very safe, but we really don't know. In Canada we are fortunate enough to have adequate vaccine of the combination of Pfizer and Moderna for the very near future.
I know what I've been telling my loved ones and I'd be encouraging vaccine task forces as well at the federal level that we should be moving as quickly as possible to getting the mRNA vaccines in arms. They've proven to be exceedingly safe, and we should be affording people who rolled up their sleeve to get the AstraZeneca early on the same if not accelerated benefit as those who have held out for the mRNA vaccines.
