For AstraZeneca? I think I've heard that for the mRNA ones...

  It can and should happen for any intra-muscular vaccination in similar (very low) rates - it's a medical error when the vaccine is administered (accidentally hitting a small vein inside the muscle), not some property of the vaccine itself.

    Sure, the question isn't so much whether it happens but whether it's associated with severe side effects.
