Probably the same as you.......about 38 years ago! I will avoid a shot at all costs. And to think I used to give myself one every day!!

The Beta shots are not IM so they're not anything like a tetanus shot.
I remember my sister having to get one after she stepped on a thumb tack. I went with my Mom and sister to the Health Dept. and they gave it to her there. I screamed.....cried louder than I ever knew I could....and I wasn't even the one getting the shot! I remember the nurse and my sister laughing at me!

Note: I was only about 6.....
Tetanus shots leave such a lasting reminder. I'm like you.....I'll get one if/when I need one.
