Invasive Haemophilus influenzae type b (Hib) disease is a serious bacterial infection that disproportionally affects American Indian and Alaska Native (AI/AN) populations. Hib vaccination with a monovalent Hib conjugate vaccine consisting of Hib capsular polysaccharide (polyribosylribitol phosphate [PRP]) conjugated to outer membrane protein complex of Neisseria meningitidis serogroup B, PRP-OMP (PedvaxHIB, Merck and Co., Inc.) has historically been preferred for AI/AN infants, who are at increased risk for invasive Hib disease, because it provides substantial protection after the first dose. On June 26, 2024, CDC's Advisory Committee on Immunization Practices (ACIP) recommended that a hexavalent, combined diphtheria and tetanus toxoids and acellular pertussis (DTaP), inactivated poliovirus (IPV), Hib conjugate, and hepatitis B (HepB) vaccine, DTaP-IPV-Hib-HepB (Vaxelis, MSP Vaccine Company) should be included with monovalent PRP-OMP in the preferential recommendation for AI/AN infants because of the PRP-OMP Hib component. A primary Hib vaccination series consisting of either 1) monovalent PRP-OMP (2-dose series at ages 2 and 4 months) or 2) DTaP-IPV-Hib-HepB (3-dose series at ages 2, 4, and 6 months) is preferred for AI/AN infants. DTaP-IPV-Hib-HepB is only indicated for use in infants at ages 2, 4, and 6 months and should not be used for the booster doses of Hib, DTaP, or IPV vaccines. For the booster dose of Hib vaccine, no vaccine formulation is preferred for AI/AN children; any Hib vaccine (except DTaP-IPV-Hib-HepB) should be used. This report summarizes evidence considered for these recommendations and provides clinical guidance for the use of Hib-containing vaccines among AI/AN infants and children.

美洲印第安人和阿拉斯加土著婴儿使用含 B 型流感嗜血杆菌疫苗:免疫实践咨询委员会的更新建议 - 美国,2024 年。



侵袭性 b 型流感嗜血杆菌 (Hib) 病是一种严重的细菌感染,对美洲印第安人和阿拉斯加原住民 (AI/AN) 人群的影响尤为严重。使用由 Hib 荚膜多糖(聚核糖基核糖醇磷酸 [PRP])与脑膜炎奈瑟菌血清型 B 外膜蛋白复合物共轭的单价 Hib 偶联疫苗 Hib 疫苗接种,PRP-OMP(PedvaxHIB,Merck and Co., Inc.)历来是 AI/AN 婴儿的首选,他们患侵袭性 Hib 病的风险增加,因为它在第一剂后提供了实质性保护。2024 年 6 月 26 日,CDC 免疫实践咨询委员会 (ACIP) 建议,由于 PRP-OMP Hib 成分,六价白喉和破伤风类毒素和无细胞百日咳 (DTaP)、灭活脊髓灰质炎病毒 (IPV)、Hib 结合物和乙型肝炎 (HepB) 疫苗 DTaP-IPV-Hib-HepB(Vaxelis,MSP 疫苗公司)应与单价 PRP-OMP 一起包含在 AI/AN 婴儿的优先推荐中。AI/AN 婴儿首选主要 Hib 疫苗接种系列,包括 1) 单价 PRP-OMP(2 岁和 4 个月时的 2 剂系列)或 2) DTaP-IPV-Hib-HepB(2、4 和 6 个月大时的 3 剂系列)。DTaP-IPV-Hib-HepB 仅适用于 2、4 和 6 个月大的婴儿,不应用于 Hib、DTaP 或 IPV 疫苗的加强剂量。对于 Hib 疫苗的加强剂量,AI/AN 儿童没有首选疫苗配方;应使用任何 Hib 疫苗(DTaP-IPV-Hib-HepB 除外)。本报告总结了这些建议所考虑的证据,并为 AI/AN 婴儿和儿童使用含 Hib 的疫苗提供了临床指导。
