Just curious as I've recently had DTAP and then Covid vaccines, and rather than being in the middle of my upper arm muscle, as all my school ones were, they've been given to me really high sort of on the corner of my shoulder.
I found them much less painful than I was expecting. Is this a new technique? Or just coincidence?
I know I'm not misremembering the school vaccines as my TB scar is in the middle of that muscle there.
