They are already setting up the narrative… several articles like this out there recently. Obviously they are expecting higher death rates and will be blaming on anything but the vax.

I am leaning towards another anon's theory that high stress be it physical or mental is the trigger for the clotting / heart attacks after the vax.
They used to run a story every year warning about shoveling snow (I actually had a buddy that died of heart attack while shoveling snow many years ago), but this year it's just the cold itself that is the problem apparently.
