A second-generation, self-amplifying COVID-19 Vaccine: World's first approval and distribution in the Japanese market with vaccine hesitancy.
Review in Human vaccines & immunotherapeutics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The mRNA vaccine is a milestone in immunotherapeutics, as symbolized by the 2023 Nobel Prize for Physiology or Medicine awarded to Drs. Karikó and Weissman. Whereas the conventional, "first-generation" mRNA vaccine was globally distributed to hundreds of millions of people to decrease COVID-19 prevalence, further advanced constructs have been pursued by researchers and pharmaceutical manufacturers. The key feature of the "second-generation" mRNA vaccine is a self-amplifying replicon that may allow a low dose to ensure durable immunogenicity. In clinical trials, ARCT-154 indeed showed effectiveness (magnitude, persistence, and breadth) superior to conventional mRNA vaccines, with similar or less frequent adverse responses, and acquired its world's first approval in November 2023 in Japan (brand name: KOSTAIVE manufactured by Meiji Seika Pharma, Tokyo, Japan) to prevent COVID-19 infection. Real-world distribution of KOSTAIVE was started in October 2024, and researchers are collecting data on its effectiveness and safety despite nonscientific, but persistent, antivaccine skepticism.
