A TT (tetanus toxoid) injection is given in the upper arm. While either arm can be used, the specific arm (left or right) is not consistently specified across resources. The choice often depends on factors like patient comfort and the healthcare provider's preference.
Injection Site Details:
- Adults and Older Children: The preferred site is the deltoid muscle in the upper arm. [Source: CDC, Cleveland Clinic]
- Infants and Young Children: The vastus lateralis muscle (thigh) is preferred. [Source: CDC]
Although some sources mention the non-dominant arm as a common choice to minimize discomfort [Source: Quora], this is not a universal standard. The primary focus is administering the injection intramuscularly (IM) into a muscle large enough to absorb the vaccine effectively.
The provided references highlight that the method of administration is intramuscular (IM) injection. While some references specify the upper arm, others mention the thigh for younger children, and the choice of left or right arm is not definitively determined. The emphasis is placed on proper intramuscular administration rather than a specific arm preference.
