The pneumococcal heptavalent conjugate vaccine protects children aged less than 2 years old from invasive pneumococcal disease (IPD). Efficacy is 89-93% in the US population and 71-86% in European studies. The vaccine confers active immunization against the main serotypes causing IPD (4, 6B, 9V, 14, 18C, 19F y 23F). We describe 2 children who presented with pneumococcal meningitis caused by nonvaccine serotypes. As a result of the widespread use of the heptavalent vaccine, there may be a shift in the serotypes causing IPD.
肺炎球菌七价结合疫苗可保护2岁以下儿童免受侵袭性肺炎球菌疾病（IPD）的侵害。在美国人群中，其有效性为89%-93%，在欧洲的研究中为71%-86%。该疫苗可对引起IPD的主要血清型（4、6B、9V、14、18C、19F和23F）进行主动免疫。我们描述了2例由非疫苗血清型引起的肺炎球菌脑膜炎患儿。由于七价疫苗的广泛使用，引起IPD的血清型可能会发生变化。
