Vaccine Dose, Route, Site, and Needle Size — Transcript-Based Study Notes

Diphtheria, Tetanus, Pertussis (DTaP, Tdap, Td)

  • Dose: 0.5\ \text{mL}

  • Route: Intramuscular (IM) injection (typical for these vaccines)

  • Site considerations (in general):

    • Infants and young children often receive IM injections in the anterolateral thigh muscle; older children and adults may receive IM injections in the deltoid muscle.

  • Needle size/length considerations are not explicitly listed in this block for DTaP/Tdap/Td beyond the general guidance elsewhere in the document; however, there is a broader note about alternate needle lengths when skin is stretched.

Administering Vaccines: Dose, Route, Site, and Needle Size (general framing)

  • The document presents dose, route, site, and needle size for multiple vaccines.

  • It references product-specific guidance (package inserts) and ACIP recommendations for each vaccine.

  • It emphasizes using the package insert and ACIP recommendations for complete administration details.

  • It provides links to Immunize.org resources for current guidance and ACIP recommendations.

Dengue (DENV4CYD)

  • Route: IM or Subcutaneous (Subcut) injection

  • Injection Site and Needle Size: Use a 23–25 gauge needle

  • Additional notes: Data appears garbled in places; the core details above are captured from the transcript

Haemophilus influenzae type b (Hib)

  • Dose: 0.5\ \text{mL}

  • Route: IM

  • Site/Needle details: The transcript lists “LENGTH” and “INJECTION SITE” without complete context; standard practice is IM injection into the deltoid or anterolateral thigh depending on age
