Which of the following best describes IIV intradermal administration?

Intradermal administration of the seasonal influenza vaccine (IIV) is specifically designed to deliver the vaccine within the dermal layer of the skin. This method typically utilizes a small gauge needle that allows for the vaccine to be deposited just beneath the surface of the skin rather than deeper into muscle tissue.

The choice that stands out correctly aligns with this technique because it emphasizes the positioning of the syringe. Administering the injection perpendicular to the skin ensures that the needle penetrates straight into the dermal layer, which is essential for effective intradermal delivery. This angle helps facilitate the absorption of the vaccine by the immune cells present in the skin.

In contrast, other options misrepresent the correct technique or position. Administering the vaccine at a 45 degree angle is more aligned with subcutaneous injections, not intradermal. Similarly, inserting the needle under the skin in the forearm does not indicate the proper site for the vaccine; the intradermal injection is typically given on the inner forearm. The use of a 5/8" needle, although it could be appropriate for some intradermal administrations, is not specifically accurate for all intradermal injections, as this generally uses shorter 1/
