摘要

在儿童中实施肺炎球菌结合疫苗（PCV7和PCV13）已导致疫苗型肺炎球菌感染的急剧减少，并通过群体免疫对成人产生额外益处。然而，血清型3、19A和19F在儿童中的水平仍然很低，而新的非疫苗血清型（NVTs）现在在IPD中占主导地位。在欧洲批准的新型肺炎球菌疫苗中，PCV20覆盖了40%以上的侵袭性分离株，而PCV15覆盖不到10%。一些nvt，如24F，不包括在PCV20中，仍然存在问题。未来疫苗的选择将取决于它们覆盖这些替代血清型的能力。©2024作者。Elsevier Masson SAS出版。

Spectre potentiel d'activité des nouveaux vaccins contre le pneumocoque

The implementation of pneumococcal conjugate vaccines (PCV7 and PCV13) in children has led to a dramatic reduction in vaccine-type pneumococcal infections, with additional benefits for adults through herd immunity. However, serotypes 3, 19A, and 19F persist at low levels in children, and new non-vaccine serotypes (NVTs) now predominate in IPD. Among the new pneumococcal vaccines approved in Europe, PCV20 covers more than 40% of invasive isolates, compared to less than 10% for PCV15. Some NVTs like 24F, not included in PCV20, remain problematic. The choice of future vaccines will depend on their ability to cover these replacement serotypes.
