A number of European countries (including Ireland, France, the Netherlands, Sweden and the United Kingdom) indicate an increase seen during 2022, particularly since September 2022, in the number of cases of invasive Group A Streptococcus (iGAS) disease among children less than ten years of age.
The study compares the incidence and serotype distribution of invasive pneumococcal disease (IPD) for pneumococcal meningitis and non-meningitis IPD in children from 2007 to 2010 with reference to the pre-vaccination period from 1997 to 2001 in Germany.
The authors present an appraisal of the pneumococcal epidemiological situation in 11 Central European countries. Data are based on study findings presented at the 12th Central European Vaccine Advisory Group (CEVAG) meeting, held on 21–22 May 2010 in Sofia, Bulgaria, and a literature review of the PubMed database.
The heptavalent pneumococcal conjugate vaccine (PCV7) targets seven of the more than 92 pneumococcal serotypes. Concerns have been raised that non-vaccine serotypes (NVTs) could increase in prevalence and reduce the benefits of vaccination. Indeed, among asymptomatic carriers, the prevalence of NVTs has increased substantially, and consequently, there has been little or no net change in the bacterial carriage prevalence.
