A novel GMMA-based gonococcal vaccine demonstrates functional immune responses in mice.
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 9 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
Gonorrhea, caused by Neisseria gonorrhoeae (GC) represents a significant public health threat that may be mitigated by an effective vaccine. Vaccines containing N. meningitidis outer membrane vesicles (OMVs), such as 4CMenB, demonstrated moderate effectiveness in preventing GC infections. Here, we developed NgG, an investigational GC vaccine based on Generalized Modules for Membrane Antigens (GMMA). NgG includes genetically detoxified OMVs from the FA1090 strain, engineered to reduce endotoxin activity and limit immune interference. NgG induced a robust immune response in mice and outperformed the comparator vaccine 4CMenB in several serological and functional tests. Immunization with GMMA from a FA1090 mutant, where major oligosaccharide epitopes are incomplete or absent, revealed that NgG lipooligosaccharide plays a major role in the breadth of functional responses, with protein component also contributing in some GC strains. These results suggest that NgG has the potential to block GC infection through various mechanisms, supporting further vaccine development.
