Preclinical immunogenicity and safety evaluation of MDCK cell-derived quadrivalent influenza virus subunit vaccine.
Article in Frontiers in immunology, 2026. 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
To address the limitations of egg-based influenza vaccine production, serum-free suspension culture of Madin-Darby Canine Kidney cells (MDCK) has emerged as a promising alternative. In this study, a quadrivalent influenza virus subunit vaccine was developed using this platform by culturing four viral strains, followed by purification, inactivation, and formulation. Preclinical safety evaluations in rats, rabbits, and guinea pigs demonstrated no systemic toxicity. In mice, immunization with the vaccine elicited significant hemagglutination inhibition and microneutralization antibodies against H1N1, H3N2, BY, and BV strains at 28 and 42 days post-vaccination. These results indicate that the vaccine candidate possesses a favorable safety profile and induces robust immunogenicity.
