TY - JOUR T1 - IMmunization injections AU - Hammer S, Backer H, Schechter R Y1 - 2004/07/01 N1 - 10.1001/archpedi.158.7.708-b JO - Archives of Pediatrics & Adolescent Medicine SP - 708 EP - 708 VL - 158 IS - 7 N2 - Nearly all inactivated vaccines recommended during infancy in the United States are licensed only for intramuscular injection. An exception, inactivated poliovirus vaccine, may be given intramuscularly or subcutaneously. To ensure intramuscular penetration when immunizing infants approximately 2 months old, the American Academy of Pediatrics, Elk Grove Village, Ill2; the American Academy of Family Physicians, Leawood, Kan; and the federal Advisory Committee on Immunization Practices, Atlanta, Ga,3 recommend a needle length of 2.22 to 2.54 cm (⅞-1 in). In contrast, Reis and colleagues immunized infants of this age with needles 1.59 cm (⅝ in) in length. The bore of the needles used in their study was 26 gauge, narrower than the recommended range of 22 to 25 gauge.2- 3 SN - 1072-4710 M3 - doi: 10.1001/archpedi.158.7.708-b UR - http://dx.doi.org/10.1001/archpedi.158.7.708-b ER -
