Why not in fat just under the skin, straight in a vein, or even up the nose, given that's where we're most likely to encounter the virus? Muscles make an excellent vaccine administration site because muscle tissue contains important immune cells. Lymph nodes are important parts of the immune system which contain cells that create antibodies that prevent viruses from entering human cells or activate immune cells that destroy cells already infected by viruses. Muscle tissue also tends to keep vaccine reactions localized. The bulky muscles have good vascularity, and therefore the injected drug quickly reaches the systemic circulation and thereafter into the specific region of action, bypassing the first-pass metabolism. Nevertheless, the problem has received growing attention in recent years as more immunizations are done outside doctors offices, especially during flu season through vaccination clinics offered at workplaces, pharmacies and grocery stores.
