A live attenuated NS1-deficient vaccine candidate for cattle-origin influenza A (H5N1) clade 2.3.4.4.b viruses.
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 6 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
Avian Influenza viruses (AIVs) present a public health risk, especially with seasonal vaccines offering limited protection. AIV H5N1 clade 2.3.4.4b has caused a multi-state outbreaks in the United States (US) poultry and cattle since March 2024, raising pandemic concerns. We developed a nonstructural protein 1 (NS1)-deficient mutant of a low pathogenic version of the cattle-origin human influenza A/Texas/37/2024 H5N1, namely LPhTXdNS1, and assessed its safety, immunogenicity, and protection efficacy. LPhTXdNS1 is attenuated in vitro, showing reduced replication efficiency in Vero cells and inability to control IFNβ promoter activation. The LPhTXdNS1-immunized C57BL/6 J mice exhibit significantly reduced viral replication and pathogenicity compared to those infected with the low pathogenic version expressing NS1, namely LPhTX. Notably, a single intranasal dose of LPhTXdNS1 elicited protective immune responses, providing robust protection against lethal wild-type H5N1 challenge. These results demonstrate that LPhTXdNS1 is safe and able to induce protective immune responses against H5N1.
