Why are I.V.s put in a vein and immunizations and shots stuck in the arm?

Question

Wouldn't they work better put in a vein?

Answer 1

IV's are IV largely because they allow pretty large volumes to be infused rapidly, though often they're put in more as a precaution than for a real need.

Immunizations are small-volume affairs, and there's no hurry to get them in the system. A large number of antigens given quickly might even increase the risk of adverse effects without increasing effectiveness, but even if that isn't the case, there's just no reason to bother.

Answer 2

No, because then the immunization is traveling in the bloodstream and thus much more mobile and hard for the anti-bodies to track. In a muscle the antibodies can investigate the "infection" and create a countermeasure appropriately. It actually helps if you add some extra pain to the process so the anti-bodies react faster (I heard they intend on using tattoo guns in the future to give shots because the pain helps cause a faster reaction)

Answer 3

I.V.s are put in the vein because its a quickier way to get meds into your body. Shots and other stuff have a diffrent purpose, therefor it doesnt need to be stuck in a vein. I think i got it right.
