Tetanus Vaccine: Where to Get the Shot & Why It Matters

Mexican health authorities explain where tetanus vaccinations are administered, clarifying procedures for adults, babies, and pregnant women. The tetanus vaccine is given intramuscularly, deep into muscle tissue, to maximize the immune response.

Adults and adolescents receive the shot in the deltoid muscle, the upper arm, ideally in the non-dominant arm. For infants and children under two, the vaccine goes into the vastus lateralis muscle in the thigh, as their arms lack sufficient muscle mass.

Pregnant women also receive the vaccine in the deltoid, safely transferring protective antibodies to the fetus. Maintaining immunity requires a booster every ten years, or sooner, within five years, if a deep or dirty wound occurs. Mild side effects like soreness and redness are common and can be managed with cold compresses and gentle movement.
