A narrative review on the effectiveness of PPSV23 vaccination in adults in China.
Review in Human vaccines & immunotherapeutics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Pneumococcal Polysaccharide Vaccine (PPSV23) is available for free in some Chinese cities for elderly patients and those with comorbidities. However, there is a lack of studies summarizing its preventive effect specifically in Chinese adults. This review aims to discuss the epidemiology of pneumococcal disease, coverage and effectiveness of PPSV23 vaccination, elderly individuals and patients with comorbidities, coadministration of PPSV23 vaccine with other vaccines, and future directions for its use in China. It was found that the PPSV23 vaccination rate among the elderly ranged from 1.2% to 42.1% depending on location, with an effectiveness of 9.34%(95%CI: 2.05%, 16.62%) to 57.7%(95%CI: 20.7%, 77.5%). There is a need to raise awareness of pneumococcal disease and its prevention, especially in China. To better manage pneumococcal disease in China, developing new vaccines for common serotypes and continuously monitoring serotype distribution associated with the disease is also needed.
