No sooner does the EU admit it pretty much made up the thing about blood clots and the evidence demonstrates that the AZ vaccine is about as dangerous as eating a banana, than Canada repeats the EU's folly.
This begins to look like a behind-the-scenes campaign to villify AZ, which is the only drugmaker to provide its shots at cost.
Generally-speaking, look for the folks who benefit.
At a guess, it's one of the for-profit shot suppliers spreading the fake blood clot story to naive government institutions.
