Evaluating vaccine effectiveness (VE) against influenza infections is important to inform future vaccine programs. A test-negative case-control study was conducted in five tertiary hospitals in Hangzhou, the capital city of Zhejiang province, China, enrolling medically-attended patients aged >6 months who presented with influenza-like illness (ILI) from October 1, 2023, to March 31, 2024. The VE was estimated using multivariate logistic regression models adjusted for sex, age, influenza detection methods, and influenza testing timing. Of the 157,291 medically-attended ILI participants enrolled 56,704 (36%) tested positive for influenza. Adjusted overall VE against any medically-attended influenza infection was 48% (95% Confidence interval [CI]: 46%-51%). The overall VE of the trivalent inactivated influenza vaccine (IIV3) was 59% (95% CI: 50%-66%), followed by the trivalent live attenuated vaccine (LAIV3) (VE = 53%, 95% CI: 42%-62%) and quadrivalent inactivated influenza vaccine (IIV4) (VE = 47%, 95% CI: 45%-50%). IIV3 provided even better protection against medically-attended influenza B infection than IIV4 (VE = 87%, 95% CI: 81%-92% for IIV3 versus VE = 53%, 95% CI: 50%-57% for IIV4).

Their rapid advancement, particularly during the COVID-19 pandemic, is the result of decades of research and numerous technological breakthroughs. These discoveries build upon each other, forming dense, interconnected networks of progress. Studying the technological development paths of mRNA vaccines is therefore essential. Main path analysis (MPA) is particularly effective for mapping out development trajectories within complex and interconnected networks, which serves as a powerful tool for identifying key nodes and innovations. This study introduces a novel approach to extracting main paths from a patent citation network in the mRNA vaccine field. Initially, we shielded edges connecting the origin and terminus patents. Subsequently, we extracted the main paths from intermediate patents, and then, we reintegrated the edges connecting the origin and terminus patents based on the citation relationships, resulting in a comprehensive extraction of the main paths. The research findings indicate a consistency among the global main paths, global key-route main paths, local forward main paths, and local key-route main paths within the mRNA vaccine field. The patents on the main paths predominantly focus on nucleic acid modifications and delivery systems. The local backward main paths identify a greater number of patents, especially those related to litigation, offering a richer and more diverse set of technological insights. This study significantly advances the methodology of MPA, with the innovative shielding technique offering a fresh perspective for navigating complex networks and providing a deeper understanding of technological development in the mRNA vaccine domain.","PeriodicalId":49067,"journal":{"name":"Human Vaccines & Immunotherapeutics","volume":"21 1","pages":"2454078"},"PeriodicalIF":4.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants who had received the 2-dose mRNA-1273 100-µg primary series in the TeenCOVE trial (NCT04649151) were offered the mRNA-1273 50-μg booster. Primary objectives included safety and inference of effectiveness by establishing noninferiority of neutralizing antibody (nAb) responses after the booster compared with the nAb post-primary series of mRNA-1273 among young adults in COVE (NCT04470427). Binding antibody (bAb) responses against SARS-CoV-2 variants of interest and COVID-19 incidence after vaccination were also evaluated. Median boosting interval was 315 days. The mRNA-1273 booster was well-tolerated, with an acceptable safety profile. Relative to pre-booster, nAb geometric mean levels increased after the booster by 17.8-fold and 4.7-fold among pre-booster SARS-CoV-2-negative and -positive participants, respectively. Effectiveness was successfully inferred based on noninferiority of nAb levels from mRNA-1273 booster dose (Day 29) compared with nAb levels after mRNA-1273 primary series (Day 57) among young adults in COVE. Further, the booster increased bAb levels relative to pre-booster baseline against SARS-CoV-2 variants (alpha [B.1.1.7], beta [B.1.351], gamma [P.1], and delta [B.1.617.2]), regardless of pre-booster SARS-CoV-2 status. COVID-19 incidence (cases per 1000 person-months) was lower among boosted (0 cases) than non-boosted (95.766 cases) participants in January 2022, a peak period during the early omicron transmission. In summary, the mRNA-1273 50-μg booster induced robust nAb responses in previously vaccinated adolescents, regardless of SARS-CoV-2 serostatus. Effectiveness was successfully inferred and the booster was well-tolerated, with no new safety concerns identified.","PeriodicalId":49067,"journal":{"name":"Human Vaccines & Immunotherapeutics","volume":"21 1","pages":"2436714"},"PeriodicalIF":4.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite efforts like school-based influenza vaccination programs in the UK and free influenza vaccines in Australia, vaccination rates continue to decline.

An online questionnaire was distributed and analyzed. Bivariate analyses and logistic regression models were used to identify relevant factors. Two hundred and three patients from 243 non-vaccinated respondents were included in the analysis. A total of 167 (82.3%) respondents continued to decline vaccination, with individuals holding stable employment and higher family income displaying significantly lower intent (p < .05). The primary factors contributing to their hesitancy were misinformation and apprehension regarding potential side effects. Obtaining vaccine information from online sources, particularly text-based content, and apprehensions surrounding the adverse effects of COVID-19 vaccination were also found to significantly diminish willingness to receive the vaccine (p < .01). The present study revealed that unreliable information about vaccines is a key factor of hesitancy among non-vaccinated IBD patients.

Targeted clearance of senescent cells can markedly ameliorate these aging-related diseases. Here, we developed a novel nanovaccine (GK-NaV) loaded with seno-antigen that is self-assembled from the fusion of cationic protein (K36) and seno-antigen peptide (Gpnmb). The GK-NaV could be highly engulfed by bone marrow-derived dendritic cells (BMDCs) and efficiently present antigens on the cellular surface, thereby promoting DCs maturation and activation of CD8+T cells in vitro. Following subcutaneous immunization, GK-NaV not only exhibited a noticeable antigen depot effect but also markedly activated specific cellular immune responses, enhancing the immunoreactivity and cytotoxic effects of CD8+T cells. Consequently, the targeted anti-aging immunity triggered by GK-NaV demonstrated the ability to selectively eliminate senescent adipocytes and cardiomyocytes in high-fat diet (HFD)-induced progeroid mice, leading to a significant improvement in age-related metabolic disorders in adipose tissue and cardiac dysfunction. Hence, our findings indicate that immunization with GK-NaV targeting seno-antigens may represent a promising strategy for novel senolytic therapies.","PeriodicalId":49067,"journal":{"name":"Human Vaccines & Immunotherapeutics","volume":"21 1","pages":"2479229"},"PeriodicalIF":4.1,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11916409/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143634590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
