Following European approval of 20-valent PCV (PCV20) in March 2024, we assessed the cost-effectiveness of PCV20 versus PCV15, both under 2 + 1 schedule, among Sweden's pediatric population. A Markov state-transition model evaluated the economic and health benefits of PCV20 versus PCV15 among all ages over a 10-year time horizon. The base case adopted a Swedish payer perspective with an annual cycle length and 3.0% discount rate for costs and outcomes. Country-specific data informed population size, epidemiology, costs, and quality of life estimates. PCV15/PCV20 effect estimates were informed by PCV13 clinical effectiveness and impact studies plus PCV7 efficacy studies. Sensitivity analyses evaluated model robustness, including PCV20 under a 3 + 1 schedule. PCV20 was associated with higher quality-adjusted life year gains versus PCV15, averting an estimated 3,116 invasive pneumococcal disease cases 21,109 inpatient pneumonia cases, 6,618 outpatient pneumonia cases, and 36,209 otitis media cases, plus 3,281 pneumococcal disease-related deaths. PCV20 yielded substantial cost savings exceeding 5.4 billion SEK over a 10-year time horizon, primarily attributed to reduced direct medical costs due to improved health outcomes compared with PCV15. The findings confirmed the dominance of PCV20 in the base case, which remained robust across deterministic and probabilistic sensitivity analyses as well as scenario assessments. PCV20 was the dominant strategy versus PCV15 over 10 years. The broader serotype coverage of PCV20 suggests superior clinical and economic advantages over PCV15, warranting inclusion in Sweden's pediatric immunization program.","PeriodicalId":13058,"journal":{"name":"Human Vaccines & Immunotherapeutics","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266664","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}

The COVID-19 pandemic provided an unprecedented opportunity to better understand Indigenous perceptions about vaccination. The aim of this study was to explore perceptions of COVID-19 vaccine and other factors influencing COVID-19 vaccine acceptance as evidenced by public posts and comments on Facebook by Indigenous peoples in Quebec, Canada. We collected data on 95 Facebook pages or groups used by Indigenous peoples in Quebec between November 1, 2020, to June 15, 2021. To identify posts relating to COVID-19 vaccination, a keyword search (\"vaccination,\" \"vaccine,\" \"shot,\" \"does,\" \"Moderna,\" \"Pfizer\") was carried out in English and French in the search bar of each Facebook page/group. Results show that First Nations peoples and Inuit in Quebec had important concerns about the usefulness, safety and effectiveness of COVID-19 vaccine. They also expressed fear of being used as test subjects for the rest of the population. Motivations mentioned by First Nations peoples and Inuit to get vaccinated against COVID-19 included to travel again and return to normal life with their loved ones, and the desire to protect the most vulnerable in their communities, especially Elders. Results show that Indigenous health care professionals were considered as reliable and trustful source of information regarding COVID-19, and that seeing role models being vaccinated build confidence and foster acceptance of the vaccine. Culturally adapted messages and vaccination campaigns by and for Indigenous peoples appear to be key to building trust toward COVID-19 vaccination.","PeriodicalId":13058,"journal":{"name":"Human Vaccines & Immunotherapeutics","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266663","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}

HPV vaccine requirements for school entry are an underutilized strategy to increase HPV vaccine uptake among adolescents. The purpose of this study was to understand the factors that are predictive of parents' attitudes toward schools requiring the HPV vaccine for entry into middle school. Parents of adolescents ages 11-12 y were recruited to participate in an online survey via Qualtrics. Descriptive frequencies were obtained, and sequential regression analyses were conducted controlling for demographic characteristics. A total of 1,046 participants were included in the analysis. The mean age was 40.3 y (SD = 6.3) and the majority of participants were White (74.4%) and had some college education or higher (80.9%). Participant's gender, political affiliation, urban/rural setting, and education level were significantly associated with attitudes toward school entry requirements. Adding psychosocial items related to perceptions of benefits, risks, and social norms significantly increased the amount of variance explained in the model [(ΔR2 = .312, F(5, 1036) = 132.621)]. Perceived social norms was the strongest predictor of attitudes [β = 0.321]. The results of this study can be used to inform policy changes around school-entry requirements in the United States. Further studies are needed to assess the influence of perceived social norms in vaccine hesitant groups.","PeriodicalId":13058,"journal":{"name":"Human Vaccines & Immunotherapeutics","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266665","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}

We aimed to explore the near-term predictive value of neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR), absolute eosinophil count (AEC) for severe irAEs induced by PD-1 inhibitors. Data were collected from tumor patients treated with PD-1 inhibitors. NLR, PLR, and AEC data were obtained from both the previous and the current cycles of irAEs occurrence. A predictive model was developed using elastic net logistic regression Cutoff values were determined using Youden's Index. The predicted results were compared with actual data using Bayesian survival analysis. A total of 138 patients were included, of whom 47 experienced grade 1-2 irAEs and 18 experienced grade 3-5 irAEs. The predictive model identified optimal α and λ through 10-fold cross-validation. The Shapiro-Wilk test, Kruskal-Wallis test and logistic regression showed that only current cycle data were meaningful. The NLR was statistically significant in predicting irAEs in the previous cycle. Both NLR and AEC were significant predictors of irAEs in the current cycle. The model achieved an area under the ROC curve (AUC) of 0.783, with a sensitivity of 77.8% and a specificity of 80.8%. A probability ≥ 0.1345 predicted severe irAEs. The model comprising NLR, AEC, and sex may predict the irAEs classification in the current cycle, offering a near-term predictive advantage over baseline models and potentially extending the duration of immunotherapy for patients.","PeriodicalId":13058,"journal":{"name":"Human Vaccines & Immunotherapeutics","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266666","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}

Current prevention strategies, including screen-and-treat approaches, are not sufficient to resolve rising infection rates, emphasizing the need for a vaccine. Developing a syphilis vaccine necessitates a range of cross-disciplinary considerations, including essential disease-specific protection, technical requirements, economic feasibility, manufacturing constraints, public acceptance, equitable vaccine access, alignment with global public vaccination programs, and identification of essential populations to be vaccinated to achieve herd immunity. Central to syphilis vaccine development is prioritization of global vaccine availability, including access in low- to middle-income settings. Various vaccine platforms, including subunit, virus-like particle (VLP), mRNA, and outer membrane vesicle (OMV) vaccines, present both advantages and challenges. The proactive consideration of both manufacturing feasibility and efficacy throughout the pre-clinical research and development stages is essential for producing an efficacious, inexpensive, and scalable syphilis vaccine to address the growing global health burden caused by this disease.","PeriodicalId":13058,"journal":{"name":"Human Vaccines & Immunotherapeutics","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200387","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}

This study documents country-specific evidence on the prevalence of rotavirus genotypes in Europe and the Middle East to enable more precise epidemiological modeling and contribute to the evidence-base about circulating rotavirus genotypes in the post-vaccination era. This study systematically searched PubMed, Embase and Scopus for all empirical epidemiological studies that presented genotype-specific surveillance data for countries in Europe and the Middle East published between 2006 and 2021. The STROBE checklist was used to assess the quality of included studies. Proportional meta-analysis was conducted using the generic inverse variance method with arcsine transformation and generalized linear-mixed models to summarize genotype prevalence. Our analysis estimated the genotype prevalence by country across three date categories corresponding with rotavirus seasons: 2006-2010, 2011-2015, 2016-2021. A total of 7601 deduplicated papers were identified of which 88 studies were included in the final review. Rotavirus genotypes exhibited significant variability across regions and time periods, with G1P[8], G2P[4], G3P[8], G4P[8], G9P[8], and, to a lesser extent G12P[8], being the most prevalent genotypes through different regions and time-periods. Uncommon genotypes included G3P[9] in Poland, G2P[6] in Iraq, G4P[4] in Qatar, and G9P[4] as reported by the European Rotavirus Network. There was high genotype diversity with routinely identified genotypes being G1P[8], G2P[4], G3P[8], G4P[8], and G9P[8]; there was high variability across time periods and regions. Continued surveillance at the national and regional levels is relevant to support further research and inform public health decision-making.","PeriodicalId":13058,"journal":{"name":"Human Vaccines & Immunotherapeutics","volume":null,"pages":null},"PeriodicalIF":4.8,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142200414","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}
