Since 2010, Denmark has included the 13-valent pneumococcal conjugated vaccine (PCV-13) in the childhood immunization programme. However, serotype 3 remains as an important cause of invasive pneumococcal disease (IPD) in Denmark. IPD surveillance data (1999-2016) was used to calculate the incidence and age-distribution of serotype 3 IPD, and the effect of PCV-13 on serotype 3 IPD incidence was examined. The incidence of serotype 3 IPD in the age group below 65 years was 0.51/100,000 pre PCV-13, and 0.45/100,000 post PCV-13. In the group 0-4 years, serotype 3 IPD incidence was 0.28/100,000 pre PCV-13, and 0.16/100,000 post PCV-13. Serotype 3 IPD incidence in the elderly showed a mean of 4.27/100,000 pre PCV-13, and 4.32/100,000 post PCV-13. PCV-13 childhood immunization in Denmark has not lead to a reduction of the incidence of IPD caused by serotype 3. The reason behind this missing effect needs to be investigated further.
自2010年以来，丹麦已将13价肺炎球菌结合疫苗（PCV-13）纳入儿童免疫规划。然而，在丹麦，3型血清型仍然是侵袭性肺炎球菌疾病（IPD）的一个重要病因。利用IPD监测数据（1999 - 2016年）计算3型血清型IPD的发病率和年龄分布，并研究PCV-13对3型血清型IPD发病率的影响。在65岁以下年龄组中，接种PCV-13前3型血清型IPD的发病率为0.51/10万，接种后为0.45/10万。在0 - 4岁组中，接种PCV-13前3型血清型IPD的发病率为0.28/10万，接种后为0.16/10万。老年人中3型血清型IPD的发病率在接种PCV-13前平均为4.27/10万，接种后为4.32/10万。丹麦的儿童PCV-13免疫接种并未导致3型血清型引起的IPD发病率降低。这种缺失效应背后的原因需要进一步调查。
