Reemergence of Invasive Pneumococcal Disease in Germany During the Spring and Summer of 2021

Stephanie Perniciaro et al.

Summary: The incidence of invasive pneumococcal disease (IPD) in Germany showed a declining trend in 2020-2021 under the influence of nonpharmaceutical interventions (NPIs), but exhibited variations in age and serotype specificity over time.

Evolution of pneumococcal serotype epidemiology in Botswana following introduction of 13-valent pneumococcal conjugate vaccine

Sweta M. Patel et al.

Summary: The introduction of pneumococcal conjugate vaccines has reduced invasive pneumococcal disease burden, but the effectiveness of these vaccines can be reduced by an increase in non-vaccine serotype diseases.

Impact of Pneumococcal Vaccination on Nasopharyngeal Carriage of Streptococcus pneumoniae and Microbiota Profiles in Preschool Children in South East Poland

Karolina Kielbik et al.

Summary: Poland introduced the 10-valent pneumococcal conjugate vaccine (PCV) in 2017 and conducted a study to evaluate its impact on the colonization of Streptococcus pneumoniae in healthy children. The study found that the colonization rate was slightly higher in vaccinated children compared to unvaccinated children. Additionally, the study identified an increase in antibiotic resistance among certain pneumococcal serotypes and a modest increase in colonization by non-vaccine serotypes.

Impact of COVID-19 Lockdown on the Nasopharyngeal Microbiota of Children and Adults Self-Confined at Home

Muntsa Rocafort et al.

Summary: The study aimed to investigate the nasopharyngeal microbiota of children and adults in Spain during the COVID-19 lockdown and its relation to SARS-CoV-2 infection and COVID-19 severity. The findings showed that the predominant bacteria in the nasopharyngeal microbiota of both adults and children were Corynebacterium and Dolosigranulum, while common pathobionts like Haemophilus and Streptococcus were limited in abundance. Infected children had higher bacterial richness and increased abundance of Fusobacterium, Streptococcus, and Prevotella. Among adults, persistent SARS-CoV-2 RNA was associated with increased abundance of an unclassified member of the Actinomycetales order. COVID-19 severity in adults was associated with decreased levels of Dolosigranulum and increased levels of Staphylococcus in the nasopharynx.

Effect of COVID-19 Pandemic on Invasive Pneumococcal Disease in Children, Catalonia, Spain

Pilar Ciruela et al.

Summary: This study analyzed the impact of COVID-19 on healthcare demand and invasive pneumococcal disease in children in Catalonia, Spain. It found significant reductions in healthcare activities and incidence of invasive pneumococcal disease in 2020 compared to 2018-2019, likely due to the implementation of nonpharmaceutical measures during the COVID-19 pandemic.

Increased Incidence of Invasive Pneumococcal Disease among Children after COVID-19 Pandemic, England

Marta Bertran et al.

Summary: In England, after the removal of COVID-19 restrictions in July-December 2021, the incidence of invasive pneumococcal disease in children under 15 years old was higher compared to the same period in 2020 and the pre-pandemic years of 2017-2019. This highlights the potential risk following the relaxation of COVID-19 restrictions, emphasizing the need to maintain childhood vaccine coverage to protect the population.

Impact of Pneumococcal Vaccination in the Nasopharyngeal Carriage of Streptococcus pneumoniae in Healthy Children of the Murcia Region in Spain

Santiago Alfayate Miguelez et al.

Summary: The study found that PCV13 vaccine played a significant role in reducing carriage of vaccine serotypes, but non-vaccine serotypes were more common, and high resistance rates to certain antibiotics were observed.

Non-vaccine serotype pneumococcal carriage in healthy infants in South Africa following introduction of the 13-valent pneumococcal conjugate vaccine

Z. Skosana et al.

Summary: The study investigated pneumococcal carriage and serotype distribution among children in South Africa after the introduction of pneumococcal conjugate vaccines, finding that carriage rates varied by age group and non-vaccine serotypes were prevalent. The results provide valuable information for vaccine policy and public health practice.

Re-emergence of invasive pneumococcal disease (IPD) and increase of serotype 23B after easing of COVID-19 measures, Switzerland, 2021

Carlo Casanova et al.

Summary: In Switzerland during the first six months of 2021, the incidence of invasive pneumococcal disease rebounded as COVID-19 measures were relaxed, with the emergence of non-vaccine type serotype 23B which is associated with reduced susceptibility to penicillin. This highlights the importance of monitoring and addressing potential changes in disease patterns in the context of ongoing public health crises.
