Clinical features and immune memory of breakthrough infection in children after age-appropriate 13-valent pneumococcal conjugate vaccination in Taiwan.
Article in Infection, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeAs certain vaccine serotypes are still circulating within the community during the PCV13 era, we aimed to delineate the clinical features and assess the immunity following breakthrough infections in children.
methods101 PCVs-vaccinated children < 18 years with culture confirmed PCV13 serotype breakthrough infection (25/101, invasive pneumococcal disease [IPD]) was identified in Taiwan in 2015-2019. Immunoglobulin G (IgG) antibody levels, IgM
resultsThe majority (88%) of the breakthrough infection occurred in children under 7 years old. Infection by serotypes 3 and 19 A increased in children aged 5-17 years in 2018-2019. The pre-booster serotype 3- and 19 A-specific IgG in both children with breakthrough infection and controls were lower than the IPD protective thresholds (2.83 µg/mL for 3; 1.00 µg/mL for 19 A). Breakthrough infected children showed higher geometric mean ratio in serotype-specific IgG, IgM
conclusionsMost breakthrough infections occurred in previously healthy preschool-aged children, but such infections may still occur in school-aged children due to waning immunity. Breakthrough infections may also enhance the anamnestic response elicited by PCV13.
