À l’automne 2010, le Québec a réalisé une campagne de vaccination de masse contre la grippe pandémique A(H1N1) en utilisant presque exclusivement un nouveau vaccin adjuvanté à l’AS03 (Arepanrix, GlaxoSmithKline). Les données de surveillance recueillies durant la campagne de vaccination ont montré que le taux de déclaration d’anaphylaxie, une réaction systémique sévère souvent attribuable à l’allergie, s’est avéré être supérieur à celui historiquement observé avec les vaccins contre la grippe saisonnière (8 contre < 1 cas par million de doses, respectivement). De plus, l’évaluation systématique des déclarations de manifestations cliniques inhabituelles (MCI) d’allure allergique a démontré que l’anaphylaxie avait été sous-diagnostiquée parmi les cas déclarés. Plus du deux tiers des MCI d’allure allergique observées durant la campagne de vaccination contre la grippe pandémique sont survenues chez des femmes. En tenant compte du nombre de doses administrées, les femmes avaient un risque deux fois plus élevé que les hommes. De plus, ce risque était plus important durant les années de vie reproductive, soit entre l’âge de 20 et 49 ans. Notre étude cas-témoin appariée a identifié certains facteurs de risque dont l’histoire personnelle et familiale d’allergie, la présence d’une infection respiratoire et la prise de médicaments pour l’asthme dans les jours précédant la vaccination, le statut de travailleur de la santé, et une vaccination dans les 4 premières semaines de campagne. Toutefois, aucun de ces facteurs n’expliquait une grande partie des anaphylaxies ou des MCI d’allure allergique. La présence d’une allergie aux œufs ou au poisson, deux composantes potentiellement allergènes du vaccin, ne s’est pas avéré être un facteur de risque significatif de MCI d’allure allergique. Nous avons aussi réalisé une étude clinique en allergie auprès d’une centaine de cas déclarés durant la campagne de vaccination contre la grippe pandémique qui a montré que peu de ces événements pouvaient être attribuables à une allergie IgE-dépendante au vaccin ou à ses composantes. Cette recherche a mis en évidence le risque plus élevé d’anaphylaxie et de MCI d’allure allergique chez les femmes en âge reproducteur mais n’a pas réussi à identifier d’autres facteurs de risque majeurs. Elle a toutefois démontré que le mécanisme habituellement évoqué pour les expliquer soit la présence d’IgE ciblant une des composantes du vaccin semble jouer un rôle très mineur.

Influenza are respiratory pathogens responsible for seasonal epidemics and more occasionnally pandemics. During a season, 10 to 20 % of the global population is infected, which is a major public health problem. A/H3N2 viruses are associated with greater morbidity and mortality than A/H1N1 viruses. Vaccination remains the most effective way to control infections; however the effectiveness of these vaccines is short-lived and compromised in the event of a mismatch between circulating and vaccine strains. The first part of this thesis was devoted to the optimization of inactivated A/H3N2 vaccines by testing new adjuvants and routes of administration in mice and ferrets. It was shown that the adjuvant AS25 looks promising for the development of more effective vaccines. The second part of this thesis was devoted to the characterization of the molecular and antigenic evolution of A/H3N2 strains circulating in Quebec between 2009 and 2011. Our conclusion is that not only the number of mutations in the HA gene is important, but the nature and location of such mutations also play a key role in the antigenic drift. After characterizing the A/H3N2 strains under immune selection, we followed, in the third part of this thesis, an A/H3N2 strain under pressure with a new antiviral, laninamivir. Antivirals are the first line of defense in a pandemic or during an outbreak when there is a mismatch between circulating and vaccine strains. Our conclusion is that the viral fitness of our mutant strain is conserved in vitro but not in vivo. The different experiments done in this thesis have permitted to characterize the evolution of A/H3N2 strains and new ways of preventing or treating such infections.

Our objective was to measure seasonal influenza vaccine effectiveness (IVE) against hospitalisation with laboratory-confirmed influenza in Europe among adults. Between 2011 and 2017, we coordinated a multicenter case-control study in 29 hospitals in 12 countries. We pooled and analysed the data after every season. Between 2011-12 and 2016-17, we recruited 3436 influenza cases and 5969 controls. Pooled across seasons, IVE against any influenza was 26%; 40% patients aged 18-64 yeas, 25% among those aged 65-79 years, and 23% among those aged ≥80 years. Season specific IVE ranged between 15% in 2016-17 and 44% in 2013-14. IVE was particularly low among elderly in seasons dominated by the A(H3N2) viruses; it was 10% in 2011-12 and 2016-17 in people aged ≥80 years. Our results suggest a low to moderate IVE against influenza hospitalisation in adults. Evaluating complementary prevention options, such as prophylactic antiviral use, vaccination of health care workers and non-pharmaceutical interventions should be a priority

Equine influenza virus (EIV) and equine herpesvirus-1 (EHV-1) are frequently described in many countries and are two endemic pathogens in the French equine population. These infectious diseases have important consequences both in terms of animal health and welfare and in terms of economic impact. The fight against these viruses is essentially based on the implementation of preventive measures such as vaccination. Despite this epizootics of EIV and EHV-1 are regularly declared in France and throughout the world. Neutralising antibodies, synthesised in response to infection or after immunisation, represent the main line of defence against these viruses. Improved vaccines and a wider range of tools to measure neutralising antibodies can be a valuable strategy in the fight against these viruses. In order to improve the efficacy of the vaccine response, both in magnitude and duration, the use of adjuvants is one way to improve immunogenicity. This thesis consisted, in the first instance, in establishing the proof of concept of the use of iPPVO as an innovative adjuvant in vivo in horses in the context of vaccination against EIV. For this purpose, antibodies were measured by SRH, a method for which the correlates of protection are well defined. The addition of iPPVO at vaccination significantly increased the antibody level to EIV and protection in horses up to 6 months after immunisation. In a second step, a new method for measuring EIV antibodies in serum based on impedancemetry was developed to improve on current methods and facilitate high throughput analysis. This neutralisation test correlated well with SRH test. Another study was performed, which demonstrated the adjuvant potential of iPPVO in horses during vaccination against EHV-1,4. The antibody response measured by serum neutralisation increased up to 5 months after immunisation. Finally, preliminary results on the mechanism of action of iPPVO on peripheral blood mononuclear cells demonstrated the importance of the interferon
Silva, Maria Laura. "The role of information in decision-making : an application to seasonal influenza vaccination policy." Thesis, Lyon, 2016. http://www.theses.fr/2016LYSE2019.
Seasonal influenza complications may cause hospitalization and even death. Despite the existence of vaccination recommendations to risk-groups, the vaccination coverage rates (VCR) in most European countries are low. Currently, few studies have been undertaken to explain this phenomenon. Information asymmetry between target groups, vaccinators and health authorities may possibly explain the low VCR. This thesis aimed at investigating (1) the economic burden of seasonal influenza in France, (2) the decision-making process for developing seasonal vaccination recommendations and (3) the incentives that would motivate general practitioners (GPs) to promote vaccination. A prospective survey conducted with laboratory-confirmed cases of influenza has shown the important economic impact of influenza under the perspective of the French Health Insurance. The main cost drivers are hospitalizations and daily allowances. Interviews with key actors, in France and in the Netherlands, involved in the development of vaccination recommendations explored their perceptions about the decision-making process and the influence of economic evaluations and other information on decisions. No systematic grading of the evidence was observed, whereas it was considered of low quality. Similar information was used in both countries, but as experts’ judgement was crucial for the process, differences about the target groups for vaccination were observed. Financial incentives to Dutch vaccinators were associated with their higher VCR. A pilot-study web-surveyed GPs, major vaccinators in France, about the influence of existing financial and non-monetary incentives. GPs were more likely to promote vaccination under non-monetary incentives. Probably because they were generally in favour of vaccinations, including the influenza vaccine; but they seek evidence proving the effectiveness of the vaccine and transparency of vaccination recommendations

This research has as main objective to evaluate the reception and the adequacy of the advertising of the Campanha Nacional de Vacinação do Idoso Contra a Gripe of the district of São Luís do Maranhão in the year of 2006, considering its goals and its proposal of communication. Therefore, an ex-post evaluation of the implementation of the program of vaccination, classified as process of evaluation, was carried through aiming to relating the adequacy of the advertising campaign to the objectives and goals of this program, using an exploratory and qualitative approach. Documentary research, direct observation and focal group were used as techniques for data collection. Six participants of third age focal groups were carried through after the propagation of the 2006 campaign, in order to apprehend the generated effect of the communicative process in its target public. The accomplishment of each focal group was segmented in two stages. The first one was guided by a halfstructuralized script in order to motivate the quarrel of the participants on the campaign without showing its parts. The second stage was based on the exposition of the advertising parts of the campaign in order to stimulate the memory of the participants and to make possible the apprehension of the reception of the message without the interference of any imperfection in the distribution of the communication. The data collected through direct observation and the focal group participants` comments made possible the constitution of a research corpus on which an Analysis of Content was carried through by techniques of Thematic Analysis, with the purpose to compose an index which makes possible to extract, to classify and to regroup the speech of the subjects, in order to allow the identification of the elements that constituted the reception of the advertising campaign from the point of view of the integrants of its target public. Through the Thematic Analysis and the evaluation of the implementation process, it was possible to conclude that imperfections occurred in the process of distribution of parts of the advertising campaign, but they did not harm the positive results and reached number of vaccine covering in the year of 2006.
Esta pesquisa tem como principal objetivo avaliar a recepção e a adequação da publicidade da Campanha Nacional de Vacinação do Idoso Contra a Gripe do ano de 2006, no município de São Luís do Maranhão, frente a suas metas e a sua proposta de comunicação. Dessa forma, foi realizada uma avaliação ex post, classificada como avaliação de processo, no que se refere à implementação do programa, com o propósito de relacionar a adequação da campanha publicitária aos objetivos e metas do programa, utilizando uma abordagem exploratória e qualitativa. Como técnicas para coleta de dados foram utilizadas a pesquisa documental, a observação direta e o grupo focal. Foram realizados seis grupos focais com integrantes de grupos da terceira idade, após a veiculação da campanha de 2006, a fim de apreender os efeitos do processo comunicativo gerados em seu público-alvo. A realização de cada grupo focal foi segmentada em duas etapas, sendo a primeira orientada por um roteiro semiestruturado, de modo a motivar a discussão dos participantes sobre a campanha sem que fossem exibidas peças da mesma. A segunda etapa foi baseada na exposição das peças publicitárias da campanha como forma de estimular a lembrança dos participantes e possibilitar a apreensão da recepção da mensagem sem a interferência de possíveis falhas na distribuição da comunicação. Os dados coletados através da observação direta e do grupo focal possibilitaram a constituição de um corpus de pesquisa sobre o qual foi realizada uma Análise de Conteúdo, através das técnicas de Análise Temática, com a finalidade de compor um índex como forma de extrair, classificar e reagrupar as falas dos sujeitos, de modo a permitir a identificação dos elementos que constituíram a recepção da campanha publicitária do ponto de vista de integrantes de seu público-alvo. Através da Análise Temática e da avaliação do processo de implementação, foi possível concluir que ocorreram falhas no processo de distribuição das peças publicitárias da campanha, mas que não chegaram a prejudicar os bons resultados e índices de cobertura vacinal alcançados no ano de 2006.
Dugord, Clara. "Déterminants et transmission des comportements de recours à la prévention sur longue période." Electronic Thesis or Diss., Université Paris sciences et lettres, 2023. http://www.theses.fr/2023UPSLD040.
This thesis examines women's demand for preventive care, particularly cancer screenings, over a long period using data from the French E3N-Générations cohorts. We show that preventive health seeking behaviors are stable over time, with a strong effect of habit. Secondly, women who are less educated and more distant from the healthcare system are more likely to remain outside the use of preventive health services and to stop their use prematurely. Lastly, social inequalities in the uptake of cancer screening persist across generations, as a result of the transmission of preventive health seeking behaviors. By targeting more strongly women who do not seek preventive care, health policies could induce a spillover effect on the next generation, helping to reduce social inequalities in health

H5 and H7 low pathogenic avian influenza (LPAI) viruses can mutate into highly pathogenic (HP) and lead to serious problems in both animal and public health. Domestic ducks playing a pivotal role in the transmission cycle of H5 LPAI viruses, it’s essential to control and prevent the circulation and spread of these viruses in this species. A few inactivated and recombinant vaccines have been assessed in ducks, mainly for preventing HP H5N1 influenzavirus. Nevertheless, H5 LPAI virus duck vaccination is poorly documented. We generated a triple recombinant baculovirus allowing the expression of HA, NA and M proteins. The protection afforded by cell lysate expressing three recombinant proteins was assessed in Muscovy ducks against H5N3 LP virus challenge. A significant decrease of cloacal shedding and a delayed peak of tracheal shedding were observed. To improve the VLPs formation, triple recombinant plasmid was modified. HA and NA were present on the VLPs surface and were biologically active and antigenic. A quadruple recombinant baculovirus was generated by adding the M2 gene, and VLPs formation was confirmed. The protection afforded by the two types of VLPs will have to be evaluated

This work highlights the importance of well administrated vaccination as prophylactic activity, making it a key element of mathematical modeling about the spreading of an infection by Influenza H1N1 virus in a human population. The model counts with Optimal Control theory to achieve a vaccination strategy that balance infection?s prevention and your own cost in a hypothetical population exposed to a virus. The numerical solutions of ordinary differential equations systems generated by model is given via Finite Difference Method, that reveals the populational dynamics during the time while the vaccine is distributed, in various different situations of virus exposition and vaccination cost.

Human transmission of avian, highly pathogenic, H5N1 influenza viruses is currently inefficient. However, the recent geographic spread throughout the world and the increasing number of sporadic human cases increase the likelihood of virus adaptation to humans and the risk of a pandemic episode. The development of vaccines candidate against H5N1 influenza virus remains a global public health priority. This is made particularly complex because of the evolution of H5N1 viruses within multiple phylogenetic clades and subclades. Thus, the core challenge of developing a pre-pandemic H5N1 vaccine resides in defining an immunogenic composition able to induce a cross-protective immunity against ail avian strains, which are susceptible to emerge in humans. An approach based on the development of a bivalent vaccine composed of H5 and NI, which would target two essential functions in the virus, the binding of the virus to its receptor (driven by the HA) and sialidase activity involved in the production of new particles (driven by NA). Taken together, our data demonstrate the value of a vaccine approach based on the induction of anti-Nl immunity, for the broadening of the vaccine effïcacy spectrum against a large number of highly pathogenic H5N1 viruses' clades or sub-clades. They also highlight the limitations of vaccine approaches based solely on the induction of anti-H5 immunity, and propose to focus on a bivalent strategy, targeting two essential functions of the influenza virus carried by the H5 and the NI

This research examines the scale and nature of the impact of the 2009-2010 A/H1N1v pandemic over influenza vaccination behaviors and its (cross-sectional and longitudinal) predictors. Based upon data from the CoPanFlu France, it uses concepts from the health behaviors research as well as from cognitive and sociocognitive models to understand individual (social characteristics, cognitions) and contextual factors leading to vaccination decisions. We found an immediate and delayed effect of the pandemic season on vaccination behaviors of the cohort subjects. Recourse to immunization increased during the pandemic but decreased strongly in 2010-2011 and 2011-2012 compared to the 3 pre-pandemic seasons. Despite low influenza vaccination coverage, almost half of the users also relied on the protection of the seasonal vaccine. Vaccination choices during the pandemic differ according to the type of vaccination trajectory and durable changes in vaccination behaviors are limited to certain groups. Predictor analysis among subjects aged 15 and over reveals the specificity of vaccinations decisions. Uptaking the “new” pandemic vaccine was the result of a deliberate decision-making process, influenced by cognitive factors related to the pandemic context (such as perceived severity of the H1N1 flu strain and trust in public health authorities). Those who adopted the seasonal influenza vaccine (during and after the pandemic) were as usual more likely to belong to a target group and have a lower education. This decision did not rely on explicit justifications, but on habit of performing this behavior in the past. Exceptionally during the pandemic, a higher socioeconomic status also led to adoption of either vaccine. Longitudinal predictors such as age and income also demonstrated their specific effect on the course of (longitudinal) vaccination trajectories

In recent years there have been an increased interest in the scientific community for studying how patients conform, or not, to their corresponding prescribed or recommended therapies. Recent data from evaluation of vaccination policy made very clear that those behaviors have to be seen as a component of the strong relation that patients engage with their physician. They are also playing a strong role in the evaluation of treatment efficacy. Indeed the lack of measure and control of adherence to the evaluated intervention,especially in ambulatory medicine, can lead to major bias in the analysis that would give a measure of efficacy. In the context of influenza, those behaviors can have a strong impact on the epidemiology of the disease in a seasonal epidemic context and during pandemics.They concern both the acceptability of vaccination and the adherence to anti-viral therapy. We studied those dimensions through two studies, one survey of general practitioners upon the pandemic vaccinatio, and an analysis of patient adherence to antivirals. Due to its epidemic characteristics, influenza is concerned by global policies, and through those studies we discuss the relationship between those policies and patient’s adherence, and how they make a link between seasonal epidemic and pandemic
Aballéa, Samuel. "Contribution méthodologique à l’évaluation médicoéconomique des programmes de vaccination." Thesis, Lyon 1, 2015. http://www.theses.fr/2015LYO10224.
Economic evaluation plays an increasingly important role in the development of clinical recommendations and pricing and reimbursement decisions for healthcare interventions, and particularly for vaccination. Specific processes and methodological recommendations have been developed for the economic evaluation of vaccines in many countries. This thesis identifies and illustrates different methodological questions about the economic evaluation of vaccination programs based on six studies: estimation of morbidity, mortality and costs associated with cytomegalovirus infections among receivers of solid organ transplant; description of subjective health state and quality of life among women with recurrent vulvovaginal candidosis; critical review of economic evaluations of pertussis booster vaccination; critical review of economic evaluations of rotavirus vaccination; cost-effectiveness analysis of influenza vaccination for people aged 50 to 64 years; cost-effectiveness analysis of a quadrivalent influenza vaccine in Ontario. The economic evaluation of vaccines requires predicting the effectiveness of vaccination based on clinical trial data, which is particularly difficult for several reasons: the epidemiology of an infection may vary over time and space, the effectiveness against infection may differ from effectiveness against disease, and vaccination may lead to an increase or decrease in the burden of disease among non-vaccinated persons. In addition, the measurement and valuation of effects of vaccination on quality of life raises methodological questions and requires normative choices related to the facts that many vaccines target children and that the reduction in risk may improve quality of life outside illness periods. We finally establish recommendations for future economic evaluations of vaccination programs, related to the definition of vaccination strategies to compare, the choice of model structure, the estimation of clinical and epidemiological parameters, and the measure and valuation of quality of life and costs

The attitude of French girls was studied to understand the motivations and breaks to HPV.Several studies, qualitative and quantitative, were conducted in 2014-2016 on two populations, first sample of young women aged 15 to 25 years and second of mothers of girls aged 11 to 16. Our methodological approach is essentially based on the handset model from The Theory of Planned Behavior (TPB, Ajzen, 1991) and the Health Beliefs Model (HBM, Rosenstock, 1974). To find the moderators of making decision we opted for the two motivational systems described by Carver and White (1994). Finally, the experimental study we were inspired by the Prospect Theory of Kahneman and Tversky (1979). Statistical analyzes were performed using the softwares R and SPSS. Four types of treatment were carried out on the data: Analyze of comparisons (1); Principal Component Analysis (PCA) (2); Linear Regression to explain an intention to be vaccinated by some variables that allows us to make a prediction (3), and ANCOVA (4).The results provide new insights about the process of decision on vaccine acceptance. It appears that the favorable attitude to vaccination, the vaccine safety, the perceived control, and the anticipated regret play an important role in this decision process as well the doctor’s advice and family

The prevention of pertussis remains a concern in developing as well as in developed countries. This work studies the epidemiology of pertussis and the effects of vaccination within a rural African communauty of 30 000 residents : global effects in the population, effects one person-to-person transmission, and effects on the severity of the illness. A prospective cohort was studied from 1984 to 1996. To study infectiousness, vaccine efficacy was estimated as 1 minus the ratio of the secondary attack rates in the units of residence, for the relevant comparison groups. Model-based estimates were computed using the Generalized Estimating Equations to take correlation within units into account. Precision of the estimates was calculated using the bootstrap. To study severity, infection was defined biologically. Vaccine efficacy was estimated by 1 minus the relative risk of severe disease in the vaccinated infected individuals compared to the unvaccinated infected individuals. Crude incidence before immunization was 183 per 1 000 child-years at risk under age 5 years, with a 2,8 % case-fatality rate. After the introduction of the vaccination program, overall incidence dropped rapidly and dramatically, even in unvaccinated children. The vaccinated children were much less contagious than the others with a vaccine efficacy for infectiousness of 85 % (95 % confidence interval : 46 to 95 %) for children vaccinated with 3 doses. The vaccinated infected children had much less serious illnesses than the unvaccinated with a vaccine efficacy for severity of 48 % (95 % confidence interval : 39 to 55 %) for children vaccinated with 3 doses. The disease burden in children is extremely high in Africa and declines rapidly when vaccination is implemented. Pertussis vaccination reduces considerably the infectiousness, and significantly the severity, of vaccinated cases

The MIC3 DNA vaccine combined with pGM-CSF elicits strong specific humoral and cellular responses as well as providing effective and highly significant protection against chronic phase of Toxoplasma gondii infection in CBA/J mice. We demonstrated that the protection induced by MIC3 was mainly mediated by CD4+ and CD8+ T cells. Furthermore, both EGF and Lectin domains of MIC3 are involved in the protection. This study demonstrates, for the first time, that the micl-3KO Toxo Vaccine is a potent, effective and successful vaccine against acquired and congénital T. Gondii infection in female OF1 mice. This protection was associated with strong and spécifie humoral and cellular immune responses in adult mice. All pups from vaccinated mice survived and had the same weight as the control of non-infected mice. Furthermore, they exhibited significantly fewer brain cysts than pups from non-vaccinated dams (> 96% cyst reduction)

The equine influenza virus (EIV) belongs to the family Orthomyxoviridae and is one of the most important equine respiratory pathogens, especially due to the economic losses associated with outbreaks. In horses, infection with the influenza virus causes significant morbidity. Mortality is uncommon and mostly associated with complications, such as secondary bacterial infections. Although there are vaccines since the 60’s, outbreaks, caused by the H3N8 subtype, are recorded around the world, including Sweden, Japan, Australia and France. Among the current issues related to EIV, this thesis focuses on both the pathogen and the host. , The molecular diversity of EIV strains and a possible link with virulence was investigated. This work involved a monitoring of EIV strains circulating in France and brought new notions about virulence mechanisms. The problem of low responder is a phenomenon accepted but not well understood in horses. The second aspect of this thesis was to study sub-optimal response to immunisation observed in some horses. The humoral immune response monitored, through the performance of SRH tests, in 202 foals during the primary course of vaccination against equine influenza. Results allowed to define the frequency of individuals that did not develop an adequate immune response and to highlight two independent factors playing a major role in the establishment of this sub-optimal response: the age of the foal and the presence of maternal antibodies at the time of first immunisation. In a preliminary study, evaluation of mRNA cytokines expression levels induced after EI immunization did not allow identification of intrinsic factors associated with low vaccination response
