Although extensive research has examined hesitancy toward COVID-19, how the general population would respond to vaccination in a future pandemic remains unclear. Furthermore, little is known about the conditions that may reduce hesitancy. In this study, we conducted a nationwide internet survey in Japan in 2024-2025 involving 28,000 participants to assess vaccination intentions in a hypothetical future pandemic, identify factors associated with vaccine hesitancy, and examine conditions that may increase willingness to be vaccinated. We analyzed associations between individual characteristics and vaccination intention using logistic regression and explored heterogeneity in prioritized factors to determine vaccination intention using unsupervised clustering analysis. We found that only 53.1% of respondents reported intending to be vaccinated in a future pandemic-a marked decline from observed COVID-19 vaccination coverage. Notably, 35.8% of individuals who were vaccinated during the COVID-19 pandemic expressed hesitancy. Vaccination intention was lower among adults aged 20-40 years, women, individuals with lower income or educational attainment, and those endorsing misinformation or conspiracy statements. Cluster analysis identified eight distinct groups with heterogeneous priority structures. Free vaccination and evidence from clinical trials were prioritized across all clusters, whereas the prioritization of trust in authorities, social influence, domestic vaccine production, and convenience varied substantially across clusters. Public intentions to vaccinate in a future pandemic are shaped by diverse perspectives and values. Tailored strategies and risk communication approaches that address these heterogeneous concerns may be critical to strengthening preparedness for future pandemics.</p>","PeriodicalId":19335,"journal":{"name":"NPJ Vaccines","volume":"11 1","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13529798/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148866090","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although PMNs from healthy cattle exhibit antimicrobial effects against Map, the impact of vaccination on bovine PMN function remains undetermined. This study has further explored the mechanisms of trained immunity mediated by PMNs elicited by this vaccine in calves. PMN mediated phagocytosis, ROS production and NET release showed a significant increase in vaccinated calves upon stimulation in ex vivo assays. Furthermore, PMNs from vaccinated animals exhibited decreased motility that was partially restored upon ex vivo stimulation with Map. Upregulation of phagocytosis receptors such as TREM2 and PBDL1, genes related to NETosis TREM2, LYZ and F13A1 and downregulation of genes involved in chemotaxis, adhesion, and motility in vaccinated animals support these findings. Altogether, the data indicate that this inactivated Map vaccine induces changes consistent with trained immunity in calves.</p>","PeriodicalId":19335,"journal":{"name":"NPJ Vaccines","volume":"11 1","pages":""},"PeriodicalIF":7.2,"publicationDate":"2026-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13594100/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149017707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We hypothesize that next-generation CoV vaccines incorporating highly conserved SARS-CoV-2 T cell antigens would confer potent, broad, long-lasting cross-protective immunity against multiple VOCs. In this study, we identified 10 non-Spike antigens common and highly conserved across 8.7 million SARS-CoV-2 strains, prior VOCs, SARS-CoV-1, MERS-CoV, seasonal human cold CoVs, and animal CoVs. Seven antigens were preferentially recognized by CD8<sup>+</sup> and CD4<sup>+</sup> T cells from unvaccinated asymptomatic COVID-19 patients, irrespective of VOC.
