I just had Hepatitis A vaccination in the muscle on my upper left arm. I was wondering why some injections are given in muscles and others are given straight into blood vessels. not only that, but also what purpose is there in injecting the vaccine into muscle at all?

I'm not sure why some injections are given in the vein and some in the muscle tissue, but there is a good reason for intramuscular injections. Your muscles are chock full of smaller blood vessels in order to supply them with fuel and oxygen - injections given there almost instantly pass into your bloodstream

It is mostly about the way it's absorbed into the system. Things injected into the blood stream are absorbed fast. pain killers that are given intra-muscular are absorbed slower the same with vaccines. Then you have sub dermal injections like fragmin for thinning the blood and stopping blood clots. They are usually injected in the the fat under the skin of the abdomen.

Blood flow to the muscles is very high and therefore the vaccine or medicine is absorbed quickly. It is usually given in the largest muscles: in the arm, the thigh, or the behind; the arm is usually chosen as that is less hassle that having to drop your pants!

Each nurse prefers easier targets.. more fatty areas are better for injections
