Meningitis Due To Streptococcus Pneumoniae Serotype 24a In A Child Vaccinated With 13-Valent Pneumococcal Conjugate Vaccine

The introduction of conjugated pneumococcal vaccines into routine vaccination schedules resulted in a reduction in invasive pneumococcal disease due to vaccine strains. However, invasive pneumococcal diseases caused by non-vaccine strains have increased. Here, we present a fully vaccinated child with 13-valent pneumococcal conjugate vaccine, who suffered from meningitis caused by Streptococcus pneumoniae serotype 24A, a non-vaccine and very rare serotype. Longitudinal pneumococcal surveillance is important in monitorization of vaccine coverage and effectiveness and guidance for future vaccination programmes.
