Prevalence of Candidate Vaccine Targets and Genomic Features of Pediatric Invasive Streptococcus Agalactiae in Japan.
Article in The Journal of infectious diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundStreptococcus agalactiae (Group B Streptococcus, GBS) is a leading cause of invasive neonatal and infant infections, including sepsis and meningitis. This study aimed to estimate the vaccine coverage and characterize the genomic features of pediatric invasive GBS in Japan.
methodsWe conducted a nationwide, multicenter, retrospective genomic surveillance study involving 237 GBS isolates from sterile specimens of children aged ≤15 years across 35 hospitals in Japan between 2004 and 2023. Serotyping, antimicrobial susceptibility testing, and whole-genome sequencing were performed.
resultsThe estimated vaccine coverage was 98.3% for the hexavalent polysaccharide vaccine and 94.9% for the GBS-NN/NN2 protein vaccine. Erythromycin and clindamycin resistance were observed in 61.2% and 43.5%, respectively. Among the 75 CC17 isolates, 59 (78.7%) contained only PI-2B and harbored both ermB and tetO, indicating the predominance of a multidrug-resistant clone. Single nucleotide polymorphism-based analysis revealed evidence of nosocomial transmission and persistent regional circulation, particularly within the ST17 and ST23 lineages.
conclusionsThis study suggests that current maternal GBS vaccine candidates would provide broad coverage for pediatric invasive infections in Japan. The identification of persistent and regionally disseminated lineages highlights the importance of investigating potential, yet, poorly understood, transmission routes, including environmental reservoirs, to inform future prevention strategies.
