The survey was completed by 349 healthcare providers, with one respondent excluded for inconsistent entry. The mean age of respondents was 42.7 ± 10.9, and of those, 68% were female and 32% were male. Of the unvaccinated respondents, 43.3% were ≤ 45 y of age (eligible for vaccination), while those vaccinated formed 41% of the respondents. Healthcare providers are highly concerned about their cancer safety, as shown by their awareness of occupational human papillomavirus hazards and broad knowledge about vaccine efficacy. The use of personal protective equipment varied widely, including eyewear, double gloving, procedural face mask, N95 face mask, and/or nothing. Human papillomavirus and cancer risk was clearly perceived by healthcare providers. For professions, pairwise comparisons revealed that nurse practitioners, physician assistants, certified registered nurse anesthetists, and allied healthcare providers had lower scores than medical doctors. Despite the high level of understanding among healthcare providers of occupational human papillomavirus exposure, only a few of them knew of the recommendations of the ASCPP for vaccination of healthcare providers treating human papillomavirus-related diseases. In such cases, most of those surveyed embraced vaccination, which was considered 100% safe by medical doctors and allied health professionals.</p>","PeriodicalId":49067,"journal":{"name":"Human Vaccines & Immunotherapeutics","volume":"20 1","pages":"2342622"},"PeriodicalIF":4.1,"publicationDate":"2024-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11110707/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141071174","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}

A year after the vaccination program started, we conducted a population and online-based cross-sectional study, using the WHO modified Behavior and Social Drivers questionnaire among parents and caregivers in the eastern DRC. We performed Modified Poisson regressions to determine factors associated with vaccine hesitancy and outright refusal, focusing on the intention to vaccinate one's children as our primary outcome. Of the 1709 respondents aged 38 years, 82.56% were unwilling to vaccinate their children, of which 26.80% were hesitant and 55.76% were outright refusals. Drivers of hesitancy were religious refusal of vaccine, non-healthcare status, and caregiver beliefs about vaccine unsafety. Independent predictors of refusal were religious refusal of vaccine, neither healthcare nor student status and belief about vaccine effectiveness, unsafety, and distrust. In addition, both hesitancy and refusal to vaccinate one's children were driven by not being ready to get vaccinated if recommended or mandated. In contrast, parents' and caregivers' trust in the government and readiness to vaccinate themselves reduced hesitancy and outright refusal to vaccinate one's children, respectively. Briefly, COVID-19 vaccine hesitancy and outright refusal in eastern DRC are influenced by individual (subjective convictions) and system-level factors (government confidence, mandate trust).

This study aims to evaluate the cost-effectiveness of replacing the current strategy with alternative strategies utilizing non-NIP vaccines to inform policy decisions. From a societal perspective, a decision tree-Markov model was constructed to simulate the economic and health consequences of meningococcal disease in a 2019 birth cohort with four vaccination strategies. Epidemiology, vaccine efficacy, cost, and other parameters were derived from previous studies. We conducted sensitivity analyses to assess the robustness of the findings and explored prices for non-NIP vaccines that enable cost-effective strategies. Compared to the current strategy, alternative strategies using quadrivalent polysaccharide vaccine (MPV-4), bivalent conjugate vaccine (MCV-AC), and quadrivalent conjugate vaccine (MCV-4) could avoid 91, 286, and 455 more meningococcal cases. The ICERs were estimated at approximately $250 thousand/QALY, $450 thousand/QALY, and $1.5 million/QALY, all exceeding the threshold of three times GDP per capita. The alternative strategies were not cost-effective. However, if vaccine prices were reduced to $3.9 for MPV-4, $9.9 for MCV-AC, and $12 for MCV-4, the corresponding strategy would be cost-effective. The current meningococcal vaccination strategy in China could effectively prevent the disease at a low cost, but with limited serogroup coverage.

A multi-cohort Markov model was developed with a 5-year time horizon and 1-month cycle length to compare outcomes for no vaccination and one-time adjuvanted RSVPreF3 vaccination (assuming the same vaccination as for influenza vaccines). Clinical parameters (e.g., vaccine efficacy) were based on phase 3 clinical trial data over 3 seasons, with all other inputs obtained from public US sources and scientific literature. Outcomes included total and incremental quality-adjusted life year (QALY) losses and costs, as well as incremental cost-effectiveness ratios (ICERs). Sensitivity analyses were conducted to evaluate the sensitivity of results to inputs. In the base case, the model estimated that vaccinating 52.7 million adults aged ≥60 years with the adjuvanted RSVPreF3 vaccine once would result in 244,424 fewer QALY losses and an incremental societal cost of $4.5 billion over 5 years, with vaccination costs partially offset by reduced disease-related costs. From the societal perspective, adjuvanted RSVPreF3 vaccination resulted in an ICER of $18,430 per QALY gained.
