Hey guys, i got my immunity to polio and typhoid vaccine today. It was injected into my left arm. Now, whenever ive had an injection, its always been on my left arm, at the top, why is this? Can they do it on the right arm aswell?

They tend to avoid the arm you use the most, as there's a chance your arm will go numb for a while.  Other than that, there's no reason why they couldn't use either arm.

I give blood regularly, and although most of the time it's been taken from my left arm (I'm right handed), I have had it taken from my right to avoid scarring.
