Went in for my annual flu shot this am. The cute young nurse that gave me the shot was talking and after she wiped my arm with alcohol....she put a round band-aid with a clear window on it and then stuck the needle thru the clear part. There was a line of people waiting, so I didn't ask her about it.
I just googled it and found out this....
"The bandage is circular, with an adhesive membrane. A nurse cleans the patient’s arm, applies the Barrier Bandage, and then administers the shot right through the bandage. It then acts immediately as a band-aid to catch and conceal any fluids from the broken skin."
First time I've heard of it.
