When you get a shot, like a flu or COVID vaccination for example, they typically put it in your upper arm or your thigh. Are they just sort of injecting it into the muscle? Or into a vein? Either way, where does it *go*?
I have seen videos of when people get things like local anesthetic where the skin starts to balloon out where they put the liquid. Does that sort of thing happen just deeper in the body? I know our body is mostly liquid but does it just absorb? Maybe redistributed ?

Those vaccines go into the muscle tissue, they contain deactivated viruses or viral rna that will trigger an immune response from your body’s immune system. in this way your body learns to produce antibodies against the active form of the same virus, so if you are ever exposed to the active virus your body will be able to fight it off before you get sick.
