Chimeric hemagglutinin and M2 mRNA vaccine for broad influenza subtype protection.
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 4 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
Since multiple and unpredicted influenza viruses cause seasonal epidemics and even high-risk pandemics, developing a universal influenza vaccine is essential to provide broad protection against various influenza subtypes. Combined with the mRNA lipid nanoparticle-encapsulated (mRNA-LNP) vaccine platform and chimeric immunogen strategy, we developed a novel cocktail mRNA vaccine encoding chimeric HAs (cH5/1-BV, cH7/3) and intact M2 (termed Fluaxe), which confers broad protection against major circulating IAVs and IBVs, as well as highly pathogenic avian influenza. Two-dose intramuscular immunization of Fluaxe in mice elicited cross-reactive neutralizing antibodies, T cell responses, and long-lived immunity, resulting in robust protection against multiple lethal influenza virus infections and severe acute lung injuries. In particular, intramuscular administration stimulated systemic immunity together with a prominent lung tropism of memory cells. Moreover, Fluaxe immunization inhibited the inflammatory response induced by influenza infection. In summary, we conclude that Fluaxe can elicit broad cross-protection against numerous influenza subtypes.
