When Ontario and Alberta decided they would stop giving the AstraZeneca vaccine as a first dose, part of the reasoning was an abundant supply of other vaccines. But that feels like cold comfort to Canadians who eagerly lined up because "the best shot you can get is the one in your arm" and now might be feeling scared or ripped off. What options do those Canadians have? Another vaccine for a second dose? To wait and see? What can those of us who have one dose of any vaccine do in between our shots? Could any of this have been avoided, or is it just a case of the science changing?
