Incomplete vaccination in the pediatric population is a growing public health issue in high-income countries, but its determinants are poorly understood. Their identification is necessary to design target actions that can improve vaccination uptake. Our aim was to assess the determinants of incomplete vaccination in two-year-old children in France....

The COVID-19 epidemic highlighted the necessity to integrate dynamic human behaviour change into infectious disease transmission models. The adoption of health protective behaviour, such as handwashing or staying at home, depends on both epidemiological and personal variables. However, only a few models have been proposed in the recent literature t...

Background COVID-19 self-testing (ST) is an innovative strategy with the potential to increase the access and uptake of testing and ultimately to limit the spread of the virus. To maximize the uptake and reach of this promising strategy and inform intervention development and scale up, research is needed to understand the acceptability of and willi...

Although people have been repeatedly found to underestimate frequencies of common illnesses and overestimate those of rare illnesses, not much is known about this consistent bias in risk perception, termed “primary bias” in the literature, as well as the origin of its variations among different subpopulations. To fill this gap, we conducted a natio...

Background: We aimed to describe pregnant women's worry about the SARS-CoV-2 pandemic, the associated reasons, their perceived vulnerability to this infection, and factors influencing continued poor/non-existent or decreased implementation of preventive measures over time. Method: A cross-sectional study was conducted in July 2020 using a web-qu...

Unrealistic optimism, the underestimation of one’s risk of experiencing harm, has been investigated extensively to understand better and predict behavioural responses to health threats. Prior to the COVID-19 pandemic, a relative dearth of research existed in this domain regarding epidemics, which is surprising considering that this optimistic bias...

Elderly people are at high risk for pneumococcal infections. However, older age is not an eligibility factor for pneumococcal vaccination in France. Adults with certain co-morbidities or immunocompromised states are eligible for vaccination, which leaves adults aged ≥65 years without comorbidities at-risk for pneumococcal infections. The objective...

Objectives: We aimed to evaluate the effectiveness of a multifaceted procedure in improving pneumococcal and influenza vaccinations 6 months after an emergency department (ED) visit among patients aged 65 years and older. Methods: We conducted a cluster-randomized, controlled, parallel-group, open-label implementation trial in 18 EDs in France a...

Background: During the COVID-19 crisis, protests against restrictions emerged and rule violations increased, provoking peaks in new positive cases, forcing authorities in France to impose fines to slow down the spread of the disease. Due to these challenges, subsequent implementations of preventive measures in response to COVID-19 recurrences or o...

BACKGROUND During the COVID-19 crisis, protests against restrictions emerged and rule violations increased, provoking peaks in new positive cases, forcing authorities in France to impose fines to slow down the spread of the disease. Due to these challenges, subsequent implementations of preventive measures in response to COVID-19 recurrences or oth...

Background: A better understanding of the factors underlying their acceptance may contribute greatly to the design of more effective public health programs during the current and future pandemics. The objectives of the present study were to assess their acceptance after populations experienced their negative effects, and their relationships with CO...

Background The French Cancer Plan 2014–2019 had a target of 60% HPV vaccine coverage. The PAPILLON study investigated the annual age-specific vaccination initiation rates and cumulative partial and complete vaccination rates in France from 2017 to 2022. It also identified the factors associated with vaccination in different age groups and those ass...

Background Human Papillomavirus (HPV) vaccine coverage in France is below 30%, despite proven effectiveness against HPV infections and (pre-)cancerous cervical lesions. To optimise vaccine promotion among adolescents, we used a discrete choice experiment (DCE) to identify optimal statements regarding a vaccination programme, including vaccine chara...

The Dunning-Kruger premise assumes that unqualified people are unaware of their limited skills. We tested this hypothesis in the context of the coronavirus disease 2019 (COVID-19) pandemic. In this cross-sectional study, 2487 participants had to self-estimate their knowledge about COVID-19 in a questionnaire on the topic. Poor performers were more...

Background The knowledge of risk perceptions in primary care could help health authorities to manage epidemics. Methods A European multi-center study was conducted in France, Belgium and Spain to describe the perceptions, the level of anxiety and the feeling of preparedness of primary healthcare physicians towards the COVID-19 infection at the beg...

Background: The outbreak of COVID-19 has been a major interrupting event, challenging how societies and individuals deal with risk. An essential determinant of the virus' spread is a series of individual decisions, such as wearing face masks in public space. Those decisions depend on trade-offs between costs (or benefits) and risks, and beliefs ar...

The individual determinants of vaccine acceptance among health workers (HCWs) have been described in the literature, but there is little evidence regarding the impact of vaccine characteristics and contextual factors (e.g., incentives, communication) on vaccination intentions. We developed a single profile discrete choice experiment (DCE) to assess...

Because the effectiveness of a coronavirus disease lockdown in curbing coronavirus disease spread depends on public support, acquiring real-time information about the way populations reacted to the lockdown is crucial. In France, such public support remained fragile among low-income persons, probably because the lockdown exacerbated preexisting soc...

Background The outbreak of the Covid-19 pandemic and the lockdown measures have had a major impact on societies around the world. This led to sleep problems for a large part of the population. In order to assess the sustainability of sleeping troubles related to the sanitary crisis, it was crucial to measure its prevalence after the end of the Covi...

In absence of effective pharmaceutical treatments, the individual's compliance with a series of behavioral recommendations provided by the public health authorities play a critical role in the control and prevention of SARS-CoV2 infection. However, we still do not know much about the rate and determinants of adoption of the recommended health behav...

The global expansion of Aedes albopictus, together with the absence of specific treatment and vaccines for most of the arboviruses it transmits, has stimulated the development of more sustainable and ecologically acceptable methods for control of disease transmission through the suppression of natural vector populations. The sterile insect techniqu...

During the last decade, tiger mosquitoes have rapidly colonized a large number of European countries, increasing the risk of infection with mosquito-borne diseases (MBDs), and constituting an emerging health threat in the region. The objectives of the present study were to prospectively investigate changes in Self-protective Behaviors, beliefs and...

As Covid-19 spreads across the world, governments turn a hopeful eye towards research and development of a vaccine against this new disease. But it is one thing to make a vaccine available, and it is quite another to convince the public to take the shot, as the precedent of the 2009 H1N1 influenza illustrated. In this paper, we present the results...

Introduction Given today's increasing calling into question of vaccination, we have studied possible connections between alternative and complementary medical practices (CAM) and vaccine hesitancy (VH) among nurses. Method Ours was a cross-sectional study by self-administered online questionnaire addressed to a panel of nurses in Brittany. After a...

Background: The aims of the present study were to assess changes in lifestyles in the general population in response to coronavirus disease 2019 (COVID-19) lockdown and the influence of COVID-19 perceptions, as assessed by the Extended Parallel Process Model (EPPM), on these changes. Methods: Data were collected from 4005 individuals through an on...

Author summary The concurrent circulation of dengue and coronavirus disease 2019 (COVID-19) may produce many unfavourable outcomes—such as co-infections; delays in diagnosis, treatment, and mitigation measures; overwhelming of the healthcare system; underreporting of cases; deterioration in surveillance and control interventions; and exacerbation o...

In absence of effective pharmaceutical treatments, the individual’s compliance with a series of behavioral recommendations provided by the public health authorities play a critical role in the control and prevention of SARS-CoV2 infection. However, we still do not know much about the rate and determinants of adoption of the recommended health behav...

The recent emergence of the SARS-CoV-2 in China has raised the spectre of a novel, potentially catastrophic pandemic in both scientific and lay communities throughout the world. In this particular context, people have been accused of being excessively pessimistic regarding the future consequences of this emerging health threat. However, consistent...

Perceived exposure to mosquitoes plays a fundamental role in the adoption of a range of protective behaviors aiming to prevent and control mosquito-borne disease. However, it is largely unknown in the present literature to what extent perceived exposure is associated with actual exposure. Moreover, the perception of nuisance may depend on the natur...

Background: Annual seasonal influenza vaccination (SIV) is recommended for people with diabetes, but their SIV rates remain far below public health targets. We aimed to identify temporal trajectories of SIV uptake over a 10-year period among French people with diabetes and describe their clinical characteristics. Methods: We identified patients...

Background Vaccination policy in France was previously characterised by the coexistence of eight recommended and three mandatory vaccinations for children younger than 2 years old. These 11 vaccines are now mandatory for all children born after 1 January 2018.AimTo study the French population's opinion about this new policy and to assess factors as...

Rationale. Although greater attention has been recently given to the ecological determinants of health behaviours, we still do not know much about the behavioural changes induced by the spread of infectious diseases. Objective. In this study, we took advantage of a large epidemic of chikungunya, an emerging mosquito-borne disease, in French Guiana...

During the last decade, public health research has emphasised the growing public disaffection with vaccination. This contemporary vaccine hesitation (VH) refers to a delay in acceptance or refusal of vaccines, as well as agreement despite doubt and reluctance. We investigated VH among French parents of young children, with an emphasis on two key fe...

To improve population health and reduce health inequities, it will be necessary to orient policy toward the non-health sector such as housing, taking into account the environment, and especially the built environment, in which people live, work, and play. Seven principles for the analysis of health inequities and a model framing the impact of the n...

Objectives: Although greater attention has been recently given to the ecological determinants of health behaviors, we still do not know much about the behavioral changes induced by the spreading of infectious diseases. In this study, we took advantage of a large epidemic of chikungunya (CHIKV), an emerging mosquito-borne disease, in French Guiana t...

Background: Although people are likely to underestimate the frequencies of risks to health from common diseases and overestimate those from rare diseases, we still do not know much about reasons for this systematic bias, which is also referred to as "primary bias" in the literature. In this study, we take advantage of a series of large epidemics o...

Background French Guiana is a territory that has a decades-long history of dengue outbreaks and more recently, in 2014, a chikungunya outbreak. Zika virus (ZIKV) emerged in late 2015 and subsequently led to an important outbreak. Methodology/Principal findings A cross-sectional phone survey was conducted among the general population during the out...

We present here the proceedings of the 5th seminar on emerging infectious diseases, held in Paris on March 22nd, 2016, with seven priority proposals that can be outlined as follows: encourage research on the prediction, screening and early detection of new risks of infection; develop research and surveillance concerning transmission of pathogens be...

Purpose: To assess the self-reported vaccination behavior of general practitioners (GPs) when asked whether they would recommend the vaccination of a child presenting with a febrile uncomplicated common cold. Methods: We performed a cross-sectional survey in 2014 on a national sample of GPs. GPs were randomly assigned to one of eight clinical vi...

Introduction The reasons for vaccine hesitancy and its relation to individual socioeconomic status (SES) must be better understood. Areas covered This review focused on developed countries with programs addressing major financial barriers to vaccination access. We systematically reviewed differences by SES in uptake of publicly funded childhood vac...

Human behaviors are increasingly recognized to play a key role in the spread of infectious diseases. Although a set of social and cognitive determinants has been consistently found to affect the adoption of health protective behaviors aiming to control and prevent a variety of infections, little is currently known about the ecological drivers of th...

Objectives: Although people have been repeatedly found to underestimate the frequency of risks to health from common diseases, we still do not know much about reasons for this systematic bias, which is also referred to as “primary bias” in the literature. In this study, we take advantage of a series of large epidemics of mosquito-borne diseases to...

Background: Several concepts are available to explain vaccine decision making by individual and inter-individual factors, including risk perception, social conformism and altruism. However, only a few studies have quantified the weight of these determinants in vaccine acceptance. Using a conjoint analysis tool, we aimed at eliciting preferences in...

This article sought to estimate the prevalence of vaccine hesitancy (VH) among French general practitioners (GPs) and to study its demographic, professional and personal correlates. We conducted a cross-sectional telephone survey about GPs’ vaccination-related attitudes and practices in 2014 in a national panel of 1,712 GPs in private practice, ran...

Background: During the last decade, French Guiana has been affected by major dengue fever outbreaks. Although this arbovirus has been a focus of many awareness campaigns, very little information is available about beliefs, attitudes and behaviors regarding vector-borne diseases among the population of French Guiana. During the first outbreak of th...

Objectives: In recent years, vaccine hesitancy among health professionals has emerged as an important issue on public health agendas. However, we do not yet know very much about whether, and if so how, trust in institutions affects their practices. Methods: A path analysis model explaining the influence of trust on GPs' vaccine hesitancy was app...

In the lastfew years, vaccine hesitancy has considerably grown in the populations of western countries, particularly since controversies about the utility and safety of vaccines and their adjuvants recently multiplied. After a critical examination of the concept of " vaccine hesitancy " as well as its expressions through history, we will address th...

Background: This study aimed to assess: 1) vaccine hesitancy (VH) prevalence among French general practitioners (GPs) through the frequency of their vaccine recommendations, and 2) the determinants of these recommendations. Methods: Cross-sectional observational study in 2014 nested in a national panel of 1712 randomly selected GPs in private pr...

The internet is playing an increasingly important part in fueling vaccine related controversies and in generating vaccine hesitant behaviors. English language Antivaccination websites have been thoroughly analyzed, however, little is known of the arguments presented in other languages on the internet. This study presents three types of results: (1)...

In France, in a context of growing health inequalities, the need for action on life settings and, more broadly, on the social determinants of health (SDH), requires a contribution from health promotion research. Today's challenge is not only to design interventions tailored to contexts and actively targeting SDH, but also to develop innovative eval...

Our goals were to describe beliefs held by French people concerning the contagiosity of influenza and analyze the relationship of these beliefs with vaccination against seasonal flu.

Despite the existence of an effective pharmaceutical means for its prevention available now for about 70 years, influenza remains an important contributor to morbidity and mortality figures due to respiratory infectious diseases through the world. Understanding why people accept or reject being vaccinated in our societies may contribute to improve...

Controversies over the effectiveness and safety of the pandemic influenza A(H1N1)pdm09 vaccine in 2009/10 may have altered the influenza vaccination coverage in France after the pandemic season. The purpose of this study was to determine whether the pandemic affected seasonal influenza vaccination behaviours in the general population by analysing v...
