Immunogenicity and safety of DS-5670d, an omicron XBB.1.5-targeting COVID-19 mRNA vaccine: A phase 3, randomized, active-controlled study.
Trial report in PLoS medicine, 2025. 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
backgroundDS-5670d is a monovalent lipid nanoparticle-messenger ribonucleic acid vaccine against severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), containing an omicron XBB.1.5-derived antigen. This phase 3 non-inferiority study assessed the immunogenicity and safety of a single dose of DS-5670d according to participant immune status. METHODS AND
findingsParticipants aged ≥12 years were stratified according to their history of both prior SARS-CoV-2 infection plus prior coronavirus disease 2019 vaccination (subpopulation A), prior infection only (subpopulation B), prior vaccination only (subpopulation C), or no history of either infection or vaccination (subpopulation D), and randomly assigned (1:1) to receive DS-5670d or monovalent BNT162b2 omicron XBB.1.5. The primary efficacy endpoint was geometric mean titer (GMT) of blood neutralizing activity against SARS-CoV-2 (omicron XBB.1.5) and seroresponse rate at day 29 after study vaccine administration in the combined ABC subpopulations (DS-5670d, n = 362 versus BNT162b2, n = 363). Prespecified non-inferiority margins required that the lower limit of the 95% confidence interval (CI) exceeded 0.67 for the GMT ratio and -10% for the difference in seroresponse. The adjusted GMT ratio was 1.218 (95% confidence interval [CI], 1.059, 1.401). Seroresponse rates were 87.3% (DS-5670d) and 82.9% (BNT162b2); adjusted difference 4.5% (95% CI, -0.70, 9.71). Both results exceeded the non-inferiority margins and the study met the primary endpoint. Immunogenicity data in the overall ABCD population also met non-inferiority criteria. There were no apparent immunogenicity differences according to age or sex, and analyses suggested that even unvaccinated persons achieved an adequate immune response following a single dose of DS-5670d. There were no major differences in the incidence or severity of adverse events between the study vaccination groups. The main study limitation was the short duration of follow-up.
conclusionsA single dose of DS-5670d was immunogenically non-inferior to BNT162b2 and acceptably safe in persons with or without a history of prior infection and/or vaccination. Trial registration Japan Registry of Clinical Trials (jRCT2031230424).
