Maybe the interview you read was someone who had the older type injections that were given into the abdomen. Now they are just a little shot in the arm, no big deal. I gave a series of them about 20 years ago, at that time it was just a regular intramuscular injection, similar to a tetanus shot.
Thanks! I had not even heard they had a new type.
Been a while since I had rabies!
