IFITM3-deficient mice as a model for testing influenza virus vaccines via the intramuscular route.
Article in Vaccine, 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
Influenza virus infections remain a significant global health concern. Development of a universal influenza vaccine has been met with challenges, in part due to difficulties with preclinical vaccine testing in mice, which are widely available but are often poorly infected with human and avian influenza viruses. Here, we investigate whether mice lacking interferon-induced transmembrane protein 3 (IFITM3), an antiviral restriction factor, provide a suitable preclinical model for vaccine testing since we observe enhanced replication of multiple influenza virus strains in these mice. We find that IFITM3 KO mice produce a blunted antibody response to intramuscular vaccination that is increased by a booster dose. Nonetheless, their adaptive immune responses to previous infections and vaccinations were found to be functional in limiting weight loss, survival, and viral replication in challenge studies. Overall, our findings identify IFITM3 KO mice as an accessible, functionally immunocompetent preclinical model for assessment of influenza vaccines.
