different injection bandage

I got a flu shot and a Covid booster shot last weekend.

Previous times, they applied a regular bandage over the injection site. This time they used a different kind:
Inject-Safe™ Barrier Bandages

These are round and are stuck onto the skin before the injection. The adhesive is only on the white foam part around the edge of the circle. The needle goes through the center.

I liked that it let me see where the needle would be going in beforehand.

Today I wondered if the needle piercing thru the bandage could result in a tiny circle of bandage material getting injected along with the vaccine. But I learned the word "non-coring" which means that isn't supposed to happen with these.

http://injectsafebandages.com/ has a video showing a needle piercing one of these bandages on a balloon without the balloon breaking.
