Routine use of the 7-valent pneumococcal conjugate vaccine (PCV7), available since 2000, has resulted in a dramatic reduction in the incidence of invasive pneumococcal disease (IPD) attributable to serotypes of Streptococcus pneumoniae contained in the vaccine. However, IPD caused by nonvaccine pneumococcal serotypes has increased, and nonvaccine serotypes are now responsible for the majority of the remaining cases of IPD occurring in children. A 13-valent pneumococcal conjugate vaccine has been licensed by the US Food and Drug Administration, which, in addition to the 7 serotypes included in the original PCV7, contains the 6 pneumococcal serotypes responsible for 63% of IPD cases now occurring in children younger than 5 years. Because of the expanded coverage provided by PCV13, it will replace PCV7. This statement provides recommendations for (1) the transition from PCV7 to PCV13; (2) the routine use of PCV13 for healthy children and children with an underlying medical condition that increases the risk of IPD; (3) a supplemental dose of PCV13 for (a) healthy children 14 through 59 months of age who have completed the PCV7 series and (b) children 14 through 71 months of age with an underlying medical condition that increases the risk of IPD who have completed the PCV7 series; (4) "catch-up" immunization for children behind schedule; and (5) PCV13 for certain children at high risk from 6 through 18 years of age. In addition, recommendations for the use of pneumococcal polysaccharide vaccine for children at high risk of IPD are also updated.
自 2000 年以来,常规使用 7 价肺炎球菌结合疫苗(PCV7)已显著降低了侵袭性肺炎球菌病(IPD)的发病率,这归因于疫苗中包含的肺炎链球菌血清型。然而,由非疫苗型肺炎球菌血清型引起的 IPD 有所增加,并且现在非疫苗型血清型占儿童中剩余 IPD 病例的大多数。一种 13 价肺炎球菌结合疫苗已获得美国食品和药物管理局的许可,除了原始 PCV7 中包含的 7 种血清型外,该疫苗还包含导致 63%的 5 岁以下儿童发生 IPD 的 6 种肺炎球菌血清型。由于 PCV13 提供了更广泛的保护,因此它将替代 PCV7。本声明提供了以下建议:(1)从 PCV7 过渡到 PCV13;(2)对于健康儿童和存在增加 IPD 风险的基础疾病的儿童,常规使用 PCV13;(3)对于已完成 PCV7 系列接种的(a)14 至 59 个月龄的健康儿童和(b)已完成 PCV7 系列接种且存在增加 IPD 风险的基础疾病的 14 至 71 个月龄儿童,给予 PCV13 补充剂量;(4)为未按时接种疫苗的儿童进行补种;(5)对于 6 至 18 岁存在高危因素的儿童,使用 PCV13。此外,还更新了对于高危 IPD 儿童使用肺炎球菌多糖疫苗的建议。
