“Stay in the arm,” is what I asked about that early on and was assured here on FR that it was the case. I didn’t buy it.

My daughter worked for the County Public Health Department during the big vaccination drive, doing intake work. Lines of cars would drive up, roll the window down and the shot was administered in the arm. Now being a senior citizen myself, I am well aware of what muscle remains in the arms of the elderly. If “stay in the muscle” was the objective, the drivers and passengers should have been mooning the workers in that line of cars. Can’t beat the gluteus for muscle mass (presuming you could get through the fat).

Key point: "it allows the doctor or nurse to make sure that they are not inadvertently injecting fluid into a blood vessel."
