Ohio State Health and Discovery released information on Apr. 2 explaining why vaccines are commonly administered in the upper arm and detailing various methods of vaccine delivery.
The choice of injection site is important for ensuring an effective immune response. Vaccines work by prompting the body to produce antibodies, which help protect against infectious diseases. The upper arm is often chosen because it allows for optimal absorption and minimizes adverse reactions at the injection site.
Muscles such as those found in the upper arm have a rich blood supply, enabling immune cells to quickly reach the vaccine antigen and start building a defense. Muscles also contain fewer pain fibers than skin or fat, making injections less painful. In contrast, injecting into fatty tissue can delay immune response and increase irritation or inflammation.
The organization also discussed alternative methods of vaccine administration, including oral vaccines like polio or rotavirus, nasal sprays such as FluMist for influenza, intravenous immunization with monoclonal antibodies like pemivibart (Pemgarda) for people with severe immune compromise, and subcutaneous injections used for certain vaccines like MMR or yellow fever.
