Development and characterization of the genotype F attenuated mumps candidate strains.
Article in Frontiers in immunology, 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
Background: Mumps is an acute infectious disease caused by the mumps virus (MuV), primarily affecting the parotid glands, though it can also lead to systemic infections, including the nervous system. In China, the predominant circulating MuV genotype is F, while the vaccine strain (S79 or WM84) belongs to genotype A, raising concerns about immunization effectiveness. Methods: A genotype F MuV strain was isolated from throat swabs of six suspected mumps patients. Through cell adaptation passage and plaque purification, two candidate vaccine strains QBB-2BS-3.2 and QBB-2BS-9.3 were prepared. Their immunogenicity was assessed by neutralizing antibody and cell-mediated immune responses in immunized mice. Additionally, neurotoxicity was evaluated in neonatal Lewis rats. Results: Both QBB-2BS-3.2 and QBB-2BS-9.3 elicited strong neutralizing antibody responses and robust cell-mediated immune responses in mice. Notably, neurotoxicity testing revealed minimal neurotoxicity in QBB-2BS-3.2 and QBB-2BS-9.3 strains, comparable to the S79 vaccine strain. Conclusions: This study successfully developed two attenuated genotype F MuV candidate strains with favorable immunogenicity and safety profiles, laying a critical foundation for the development of genotype F mumps live attenuated vaccines.
