More than half of shoulder vaccinations may end up in the subacromial space.
Article in NPJ vaccines, 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
Shoulder Injury Related to Vaccine Administration (SIRVA) can occur as subacromial bursitis, frozen shoulder, or tendinopathy following deltoid intramuscular immunization. This study evaluated needle overpenetration into the subacromial space using a standard needle in 177 patients undergoing arthroscopic shoulder surgery from 2022 to 2024, with a median age of 55. Findings showed a mean needle length of 25.36 mm was required for subacromial penetration, occurring in 51.9% of cases. Significant associations with needle overpenetration included Body Mass Index (BMI), weight, deltoid thickness, fat thickness, and combined fat and deltoid thickness, all statistically significant (p < 0.05). These results suggest the standard needle length may be too long for most adults, increasing complication risks. To prevent subacromial injections, the study recommends vaccination guidelines to adopt a shorter 15 mm needle for most adults, ensuring proper vaccine delivery into the deltoid muscle and minimizing SIRVA risk.
