What are parents' preferences for Human Papillomavirus vaccination promotion messages and communication? Application of a discrete choice experiment to a French Caribbean setting.

Introduction: Human Papillomavirus (HPV) vaccine uptake in the French Caribbean has remained below 25% since introduction in 2007, which is well behind national and international targets. Using a discrete choice experiment (DCE), we explored parental preferences around HPV vaccination and optimized communication content in a sample of parents of middle-school pupils in Guadeloupe.

Methods: We conducted a cross-sectional survey in public and private middle age schools in Guadeloupe in June 2023 using an online questionnaire.

Mixed Conducting Oxide Coating for Lithium Batteries.

Thin, uniform, and conformal coatings on the active electrode materials are gaining more importance to mitigate degradation mechanisms in lithium-ion batteries. To avoid polarization of the electrode, mixed conductors are of crucial importance. Atomic layer deposition (ALD) is employed in this work to provide superior uniformity, conformality, and the ability to precisely control the stoichiometry and thickness of the desired coating materials.

Communicating on Vaccine Benefit-Risk Ratios: A Discrete-Choice Experiment among Health Care Professionals and the General Population in France.

Background: We explored preferences around the benefit-risk ratio (BRR) of vaccination among the general adult population and health care sector workers (HCSWs). We estimated preference weights and expected vaccine uptake for different BRR levels for a vaccine recommended during an infectious disease emergence. In addition, we explored how far qualitative information about disease severity, epidemiological context, and indirect protection interacts with these preferences.

New pedagogical tools for vaccine education: preparing future healthcare workers for the next pandemic.

Vaccine hesitancy (VH) is an issue for healthcare students, influenced by safety concerns and misinformation. The need for better communication training and understanding sociocultural factors in VH was highlighted in a European University Alliance seminar. Practical exercises like simulation role-playing, interprofessional collaboration, and digital literacy may improve vaccine education.

Sociodemographic determinants of HPV vaccine awareness, uptake, and intention among parents of adolescents in France 2021-22.

Human Papillomavirus (HPV) vaccine coverage was <50% in France in 2022 and even lower among socially disadvantaged populations. We aimed to evaluate socio-demographic determinants of HPV vaccine awareness, uptake, and intention among parents of adolescents, and related attitudes and knowledge items. Parents of adolescents attending middle schools across France, who participated in a randomized trial responded to an anonymous baseline survey, conducted between November 2021 and February 2022.

Analyzing the 7C psychological antecedents of vaccine acceptance throughout the COVID-19 pandemic among healthcare sector workers in France: A repeated cross-sectional study (CappVac-Cov).

Background: Across various stages of the COVID-19 pandemic and related vaccine recommendations in France, we assessed the association of the 7C-psychological antecedents with vaccine uptake/intention for booster vaccination among healthcare-sector workers (HCSWs). We also assessed whether 7C-antecedent profiles changed over time.

Methodology: The Research Group for the Prevention of Occupational Infections in Healthcare Workers (GERES) conducted three repeated web-surveys which were disseminated by email chain-referral among HCSWs throughout France.

Effectiveness of a School- and Primary Care-Based HPV Vaccination Intervention: The PrevHPV Cluster Randomized Trial.

Importance: The human papillomavirus (HPV) vaccine is safe and effective, yet vaccination coverage remains below public health objectives in many countries.

Objective: To examine the effectiveness of a 3-component intervention on HPV vaccination coverage among adolescents aged 11 to 14 years 2 months after the intervention ended, each component being applied alone or in combination.

Design, Setting, And Participants: A cluster randomized trial with incomplete factorial design (PrevHPV) was conducted between July 1, 2021, and April 30, 2022, in French municipalities receiving 0, 1, 2, or 3 components of the intervention.

Optimizing Communication on HPV Vaccination to Parents of 11- to 14-Year-Old Adolescents in France: A Discrete Choice Experiment.

Background: With the aim to optimize communication during HPV vaccination campaigns in France, we elicited parental preferences around HPV vaccination.

Methods: We conducted a single-profile discrete choice experiment (DCE) among parents of 11- to 14-year-old middle-school pupils, who completed an anonymous, self-administered, internet-based questionnaire during 2020-2021. The DCE comprised five attributes (vaccine-preventable disease, justification of optimal age, information on safety, indirect protection and coverage) of vaccination against an unnamed disease that were presented to respondents in ten choice tasks, or scenarios.

Are the 7C psychological antecedents associated with COVID-19 vaccine behaviours beyond intentions? A cross-sectional study on at-least-one-dose and up-to-date vaccination status, and uptake speed among adults in France.

Background: Widely documented psychological antecedents of vaccination are confidence in vaccines, complacency, convenience, calculation, collective responsibility (5C model) with the recent addition of confidence in the wider system and social conformism. While the capacity of these seven antecedents (7C) to explain variance in COVID-19 vaccine intentions has been previously documented, we study whether these factors also are associated with vaccine behaviours, beyond intentions.

Methods: From February to June 2022, we recruited a sample of adults in France, including persons with notified recent SARS-CoV-2 infection, along with relatives and randomly selected non-infected persons.

Providing parents with HPV vaccine information from a male perspective may render them more inclined to have their daughters vaccinated.

Objectives: Several high-income countries have implemented a gender-neutral vaccination program against human papillomavirus (HPV) infections. The impact of a gender-neutral program (GNP) on parental intention to vaccinate their daughters has not been studied, especially in countries with low HPV vaccine coverage among girls.

Patients And Methods: In July 2019, before a GNP was implemented in France (2021), the French National Cancer Institute (INCa) conducted a survey on HPV vaccine acceptance among parents of children aged 11-19 years living in France.

The intentions of French health university students to recommend and to receive the HPV vaccine are mainly influenced by vaccine knowledge, confidence in vaccines and personal HPV vaccination.

Introduction: Despite documented effectiveness in preventing several cancers, genital warts and safety of Human Papillomavirus (HPV) vaccine, immunization coverage among French adolescents remains far from the 80 % target. University health students (HS) in France may promote HPV vaccine through a national service (Service Sanitaire des Etudiants en Santé). We aimed to evaluate intentions to recommend the HPV vaccine to friends and relatives, to receive HPV vaccine, and to identify factors associated with these attitudes.

Can physicians and schools mitigate social inequalities in human papillomavirus vaccine awareness, uptake and vaccination intention among adolescents? A cross-sectional study, France, 2021 to 2022.

BackgroundIn France, human papillomavirus (HPV) vaccination coverage varies across socioeconomic levels.AimWe aimed at assessing HPV vaccine awareness, uptake and vaccination intention among adolescents in France.MethodsIn a cluster-randomised study, 13-15-year-old students in 61 French middle schools completed a web-based questionnaire.

Psychometric validation of a 7C-model of antecedents of vaccine acceptance among healthcare workers, parents and adolescents in France.

Support for vaccine decision-making requires a tailored approach taking into account psychological antecedents of vaccine acceptance. We aimed at validating an extended 7C-model of antecedents in three different target population groups (healthcare workers [n = 3870], parents [n = 2002] and adolescents [n = 7118]) and two vaccinations (COVID-19, HPV) in France. We performed a secondary analysis of questionnaires collecting sociodemographic characteristics, attitudes and knowledge on vaccination, and vaccine status and intention.

Impact of a COVID-19 certificate requirement on vaccine uptake pattern and intention for future vaccination. A cross-sectional study among French adults.

Background: In August 2021, France enacted a COVID-19 certificate requirement (vaccination/recovery/test) to access specific services, with mandates for professional groups. We evaluated the impact of this incentive-coercive policy in terms of vaccine uptake equality, future vaccine intention and confidence in authorities' crisis management.

Methods: In late August 2021, a representative sample of adults (18-75 years) completed an internet-based questionnaire.

Informing a target product profile for rapid tests to identify HBV-infected pregnant women with high viral loads: a discrete choice experiment with African healthcare workers.

Background: Elimination of mother-to-child transmission of hepatitis B virus (HBV) requires infant immunoprophylaxis and antiviral prophylaxis for pregnant women with high viral loads. Since real-time polymerase chain reaction (RT-PCR), a gold standard for assessing antiviral eligibility, is neither accessible nor affordable for women living in low-income and middle-income countries (LMICs), rapid diagnostic tests (RDTs) detecting alternative HBV markers may be needed. To inform future development of the target product profile (TPP) for RDTs to identify highly viremic women, we used a discrete choice experiment (DCE) and elicited preference and trade-off of healthcare workers (HCW) in Africa between the following four attributes of fictional RDTs: price, time-to-result, diagnostic sensitivity, and specificity.

Promoting HPV vaccination at school: a mixed methods study exploring knowledge, beliefs and attitudes of French school staff.

Background: HPV vaccine coverage in France remained lower than in most other high-income countries. Within the diagnostic phase of the national PrevHPV program, we carried out a mixed methods study among school staff to assess their knowledge, beliefs and attitudes regarding HPV, HPV vaccine and vaccination in general, and regarding schools' role in promoting HPV vaccination.

Methods: Middle school nurses, teachers and support staff from four French regions participated between January 2020 and May 2021.

High-spatial resolution epidemic surveillance of bacterial meningitis in the African meningitis belt in Burkina Faso.

Despite improved surveillance capacities and WHO recommendations for subdistrict analysis, routine epidemic surveillance of acute bacterial meningitis in the African meningitis belt remains largely limited to the district level. We evaluated the appropriateness and performance of analyses at higher spatial resolution. We used suspected meningitis surveillance data at health centre (HC) resolution from Burkina Faso from 14 health districts spanning years 2004-2014 and analysed them using spatio-temporal statistics and generative models.

Gut Microbes Are Associated with the Vascular Beneficial Effects of Dietary Strawberry on Metabolic Syndrome-Induced Vascular Inflammation.

Scope: Metabolic syndrome (MetS) alters the gut microbial ecology and increases the risk of cardiovascular disease. This study investigates whether strawberry consumption reduces vascular complications in an animal model of MetS and identifies whether this effect is associated with changes in the composition of gut microbes.

Methods And Results: Seven-week-old male mice consume diets with 10% (C) or 60% kcal from fat (high-fat diet fed mice; HF) for 12 weeks and subgroups are fed a 2.
