Apparently this is usually standard practice but it is deemed by the WHO and most national authorities to be unnecessary. The following link explains it far better than I can.
Perhaps we should be campaigning to include aspiration. It may save lives at negligible cost.
That doesn’t account for the fact that blood clots from the second dose of AstraZeneca are substantially less than the first, about 1/10th with (I believe) no recorded deaths anywhere in the world. If the aspiration theory had substance then there would be a similar number of adverse reactions as the first dose. There doesn’t seem to be concrete evidence that method is the reason for the clots, just a theory which one nation acted on, and no follow up studies to see it it made a difference.
