Do you get a flu shot? why or why not?

I get one, perhaps every other year. I usually forget. Recently I noticed they are now available at every drug store, grocery store pharmacy, etc. Who there would be qualified to give injections? It seems to be an urgent attempt to reach as many consumers as possible. *Edit: I searched flu shot beofre asking this and came up empty handed, but when I actually posted the question several siblings popped up…sorry.
