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 social inequalities and conflicts.

OBJECTIVES: To estimate geographical variations of child immunisation at the regional level in Senegal, to identify individual and contextual factors that could explain these regional discrepancies, and to measure their effects. METHODS: Data come from the 2015, 2016 and 2017 Senegalese Demographic and Health Survey, a national survey targeting women aged 15-49, with a questionnaire focusing on health and reproductive issues including their children's immunisation status. We restricted the analysis to children aged 12-23 months (n = 4955) and conducted a multilevel logistic regression to assess individual and contextual factors associated with complete immunisation coverage. RESULTS: The complete immunisation coverage rate of children was estimated at 68% and ranged from 41% in the region of Kedougou to 83% in the region of Dakar. The inter-regional variance was significantly different from zero (P = 0.006) in the empty multilevel model. It decreased by more than half (57 %) after adjusting for individual factors but remained significantly different from zero (P = 0.010). Regional variations of complete immunisation rates drastically decreased and were no longer statistically significant (P = 0.343) after adjusting for the following regional factors: population density, density of hospitals, literacy rate and proportion of health facilities with an antenatal care service. CONCLUSIONS: Regarding health policies designed to improve childhood immunisation and to reduce related inequalities, our results highlight the need to take into account both individual and contextual factors, with a focus on rural and deprived areas where children are at higher risk of incomplete immunisation.
OBJECTIFS: Estimer les variations géographiques de la vaccination des enfants au niveau régional au Sénégal, identifier les facteurs individuels et contextuels qui pourraient expliquer ces écarts régionaux et mesurer leurs effets. MÉTHODES: Les données proviennent de l'enquête démographique et la santé du Sénégal de 2015, 2016 et 2017, une enquête nationale ciblant les femmes âgées de 15 à 49 ans, avec un questionnaire axé sur les problèmes de santé et de reproduction, y compris le statut vaccinal de leurs enfants. Nous avons limité l'analyse aux enfants âgés de 12 à 23 mois (n = 4.955) et avons effectué une régression logistique à plusieurs niveaux pour évaluer les facteurs individuels et contextuels associés à une couverture vaccinale complète. RÉSULTATS: Le taux de couverture vaccinale complète des enfants était estimé à 68% et variait de 41% dans la région de Kédougou à 83% dans la région de Dakar. La variance interrégionale était significativement différente de zéro (P = 0,006) dans le modèle vide à plusieurs niveaux. Il diminuait de plus de la moitié (57%) après ajustement pour les facteurs individuels mais est restait significativement différent de zéro (P = 0,010). Les variations régionales des taux de vaccination complète ont considérablement diminué et n'étaient plus statistiquement significatives (P = 0,343) après ajustement pour les facteurs régionaux suivants: densité de population, densité des hôpitaux, taux d'alphabétisation et proportion d'établissements de santé disposant d'un service de soins prénatals. CONCLUSIONS: En ce qui concerne les politiques de santé conçues pour améliorer la vaccination des enfants et réduire les inégalités associées, nos résultats soulignent la nécessité de prendre en compte les facteurs individuels et contextuels, en mettant l'accent sur les zones rurales et défavorisées où les enfants sont plus à risque de vaccination incomplète.

BACKGROUND: The World Health Organization recommends recording vaccination status according to maternal recall in countries where administrative reporting systems are insufficiently reliable, as maternal recall in developing countries has been shown to be quite reliable compared with data from vaccination cards. This study aimed to investigate childhood vaccination coverage and its determinants according to the mothers' presentation of vaccination cards. METHODS: The data come from the 2017 Senegalese Demographic and Health Survey, a nationally representative household survey of women aged 15-49 years, with a questionnaire focusing on children's health. This analysis was restricted to children aged 12-35 months (n = 4032) and it assessed vaccination coverage and associated sociodemographic factors with weighted multivariate logistic regressions. Stratified multivariate logistic regressions were also performed to investigate factors associated with routine childhood immunization uptake of the Bacillus Calmette-Guérin (BCG) vaccine, recommended for administration shortly after birth, as well as of the vaccines against yellow fever and measles (recommended at 9 months). RESULTS: Comparison of vaccination coverage estimates according to the vaccination card or parental recall resulted in a 5-10% difference in estimated coverage for the BCG, pentavalent, measles, and yellow fever vaccines, but a huge difference for the polio vaccine (93.0% with the card, 32.0% without it). Presentation of the vaccination card was correlated with mothers' attendance at health facilities (suggesting it serves as a concrete manifestation of a bond between mothers and the healthcare system) and their region of residence, but it was not correlated with usually strong predictors of childhood vaccination, such as maternal education level. Factors associated with vaccinations differed depending on whether they were administered shortly after birth or later on. CONCLUSIONS: Maternal recall was found to be quite reliable except for oral polio vaccination, which raises the possibility that complete immunization coverage rates could have been significantly underestimated due to potential confusion between injection and vaccination. Considering the ability to present vaccination cards as the materialization of a bond with the healthcare system, the decision path leading to vaccination among those who lack such a bond appears longer and more likely to be driven by supply-side effects.

In the current context of crisis in the field of drug research and patients' increasing demand for greater involvement in the decision-making about their treatment, the possibility of a more personal tailored approach to medicine is emerging. This raises questions about the clinical benefits of targeted therapeutic approaches versus the cost of determining which patients are likely to benefit the most, and protecting the others from the toxicity of inappropriate treatments. Although cost-effectiveness studies shed light on this issue, the conclusions to which they point tend to be obscured by interdependence between the pricing of these tests and the cost of the treatments involved. Investigating the societal willingness-to-pay for gains in QALY (quality adjusted life year) should help to disentangle this interdependence and clarify the conclusions of cost-effectiveness studies.

OBJECTIVE: The objective of this study is to investigate young breast cancer patients' preferred and actual involvement in decision-making about surgery, chemotherapy, and adjuvant endocrine therapy (AET). METHODS: A total of 442 women aged 18-40 years at the time of the diagnosis participated in the region-wide ELIPPSE40 cohort study (southeastern France). Logistic regression analyses were performed on various factors possibly affecting patients' preferred and perceived involvement in the decisions about their cancer treatment. RESULTS: The women's mean age was 36.8 years at enrollment. Preference for a fully passive role in decision-making was stated by 20.7% of them. It was favored by regular breast surveillance (p = 0.04) and positive experience of being informed about cancer diagnosis (p = 0.02). Patients' preferences were independently associated with their reported involvement in decision-making about surgery (p = 0.01). A fully passive role in decision-making about chemotherapy and AET was more likely to be reported by patients who perceived their involvement in decision-making about surgery as having been fully passive (adjusted odds ratio = 4.8, CI95% [2.7-8.7], and adjusted odds ratio = 9.8, CI95% [3.3-29.2], respectively). This study shows a significant relationship between the use of antidepressants and involvement in decision-making about surgery, and confirms the relationship between impaired quality of life (in the psychological domain) and a fully passive role in decisions about cancer treatment. CONCLUSIONS: Patients' involvement in decision-making about chemotherapy and AET was strongly influenced by their experience of decision-making about surgery, regardless of their tumor stage and history of breast or ovarian cancer. When decisions are being made about surgery, special attention should be paid to facilitating breast cancer patients' involvement in the decision-making.

BACKGROUND: Tobacco control policies have succeeded in reducing tobacco use, but the negative correlation between smoking prevalence and socioeconomic status (SES) has increased. This study focused on the relationships between time preferences, SES, and smoking behaviour, attitudes and risk awareness. METHODS: A cross-sectional telephone survey was conducted in France in 2008 on a representative national sample of people aged 18-75 (N = 2000, including 621 smokers) years. Two scales measuring planning horizon and impulsivity and various indicators of SES were introduced into the logistic regressions performed on smoking status and smokers' attitudes to anti-smoking campaigns, quitting attempts, attempts to quit or smoke less, fear of smoking-related cancer and risk perception. RESULTS: Indicators of lower SES and smoking status were correlated with present time orientation and impulsivity. On modelling smoking status, time orientation and lower SES were found to be significant predictors. Among smokers, lower SES and present time orientation were predictive of smoking-related outcomes: little personal concern with anti-tobacco campaigns, not reporting recent behavioural changes, not expressing personal fear of smoking-related cancer and low risk awareness. When time-related preferences were introduced into the analysis, the effects of several lower SES indicators (especially a low educational level) became non-significant. CONCLUSION: The relationship between SES and smoking behaviour, attitudes and beliefs may be partly mediated by time preferences. Time preference is strongly correlated with smoking status, risk perceptions and attitudes towards anti-smoking campaigns. Tobacco control policies should include messages targeting present time-oriented smokers and/or interventions designed to enhance more future-oriented attitudes among smokers.

Cognitive impairment (CI) is common after cancer treatments, but little is known about the long-term evolution of CI, especially in premenopausal women. Since September 2005, all consecutive women included in the French National Health Insurance Fund registry with a diagnosis of primary breast cancer, aged 18-40 years and living in South Eastern France, were asked to participate in a cohort study, including telephone interviews, medical data, and prescription refills of psychotropic drugs and adjuvant endocrine therapy. At each interview, CI is defined as self-report of frequent memory loss and attention deficits. As of February 2010, 222 women with available medical data had taken part in the 10-, 16-, and 28-month telephone interviews, with CI being reported by 37.4%, 36.5%, and 42.3% of participants, respectively. Tranquilizers' dispensation was associated with CI self-report at all three interviews; chemotherapy was reported only at the 28-month interview. At 28 months, besides chemotherapy and tranquilizer's dispensation, having a low educational level and not being a native French woman were also independently associated with CI. Reports of CI were common in young women and primarily related to psycho-social vulnerabilities and cancer treatment. As they affect quality of life, long-term CI complaints deserve greater consideration.

Recent advances in cancer research have led to the development of very expensive new drugs for cancer treatment: the targeted therapies. However, the introduction of these new therapeutic agents which costs are increasing could threaten the diffusion of these innovations. It is thus necessary to determine whether the use of targeted therapies yields clinical benefits that justify their increasing cost. The development of companion diagnosis tests to target drugs and thus to select those patients most likely to benefit from the treatment may provide a useful means of containing the progress of health care expenditures and improve the cost/benefit ratio. In this paper, we present current estimates of health care expenditures linked to the use of targeted therapies for cancer care. We also discuss some of the issues related to the regulatory decisions (pricing and reimbursement) concerning the test/drug couple.

To achieve the full benefits of vaccination, it is key to understand the underlying causes of low vaccination by researching the barriers to vaccination at a local level. This systematic literature review aims to identify the reasons given by community members for the non-vaccination and under-vaccination of children and adolescents in sub-Saharan Africa. PubMed, Web of Science, PsycINFO, African Index Medicus, and African Journals Online databases were searched to identify articles published between 2010 and 2020. A total of 37 articles were included. As 17 studies did not report the reasons for non-vaccination and under-vaccination separately, we considered these two outcomes as "incomplete vaccination". The most common reasons for incomplete vaccination were related to caregiver's time constraints, lack of knowledge regarding vaccination, the unavailability of vaccines/personnel in healthcare facilities, missed opportunities for vaccination, caregiver's fear of minor side effects, poor access to vaccination services, and caregiver's vaccination beliefs.

Introduction: Like other countries, France has invested in a national medical genomics program. Among the four pilot research studies, the DEFIDIAG project focuses on the use of whole genome sequencing (WGS) for patients with intellectual disability (ID), a neurodevelopmental condition affecting 1-3% of the general population but due to a plethora of genes. However, the access to genomic analyses has many potential individual and societal issues in addition to the technical challenges. In order to help decision-makers optimally introduce genomic testing in France, there is a need to identify the socio-economic obstacles and leverages associated with the implementation of WGS. Methods and Analysis: This humanities and social sciences analysis is part of the DEFIDIAG study. The main goal of DEFIDIAG is to compare the percentage of causal genetic diagnoses obtained by trio WGS (including the patient and both parents) (WGST) to the percentage obtained using the minimal reference strategy currently used in France (Fragile-X testing, chromosomal microarray analysis, and gene panel strategy including 44 ID genes) for patients with ID having their first clinical genetics consultation. Additionally, four complementary studies will be conducted. First, a cost-effectiveness analysis will be undertaken in a subsample of 196 patients consulting for the first time for a genetic evaluation; in a blinded fashion, WGST and solo (index case, only) genomic analysis (WGSS) will be compared to the reference strategy. In addition, quantitative studies will be conducted: the first will estimate the cost of the diagnostic odyssey that could potentially be avoidable with first-line WGST in all patients previously investigated in the DEFIDIAG study; the second will estimate changes in follow-up of the patients in the year after the return of the WGST analysis compared to the period before inclusion. Finally, through semi-directive interviews, we will explore the expectations of 60 parents regarding genomic analyses. Discussion: Humanities and social sciences studies can be used to demonstrate the efficiency of WGS and assess the value that families associate with sequencing. These studies are thus expected to clarify trade-offs and to help optimize the implementation of genomic sequencing in France. Ethics Statement: The protocol was approved by the Ethics Committee Sud Méditerranée I (June 2019)-identification number: 2018-A00680-55 and the French data privacy commission (CNIL, authorization 919361). Clinical Trial Registration: (ClinicalTrials.gov), identifier (NCT04154891).
RESUMEN
The use of taxanes to treat node-positive (N+) breast cancer patients is associated with heterogeneous benefits as well as with morbidity and financial costs. This study aimed to assess the economic impact of using gene expression profiling to guide decision-making about chemotherapy, and to discuss the coverage/reimbursement issues involved. Retrospective data on 246 patients included in a randomised trial (PACS01) were analyzed. Tumours were genotyped using DNA microarrays (189-gene signature), and patients were classified depending on whether or not they were likely to benefit from chemotherapy regimens without taxanes. Standard anthracyclines plus taxane chemotherapy (strategy AT) was compared with the innovative strategy based on genomic testing (GEN). Statistical analyses involved bootstrap methods and sensitivity analyses. The AT and GEN strategies yielded similar 5-year metastasis-free survival rates. In comparison with AT, GEN was cost-effective when genomic testing costs were less than 2,090. With genomic testing costs higher than 2,919, AT was cost-effective. Considering a 30% decrease in the price of docetaxel (the patent rights being about to expire), GEN was cost-effective if the cost of genomic testing was in the 0-1,139, range; whereas AT was cost-effective if genomic testing costs were higher than 1,891. The use of gene expression profiling to guide decision-making about chemotherapy for N+ breast cancer patients is potentially cost-effective. Since genomic testing and the drugs targeted in these tests yield greater well-being than the sum of those resulting from separate use, questions arise about how to deal with extra well-being in decision-making about coverage/reimbursement.

BACKGROUND: Molecular monitoring of chronic myeloid leukemia patients treated with tyrosine kinase inhibitors is essential for therapeutic stratification. Inter-laboratory reproducibility is, therefore, a crucial issue which requires standardization and strict alignment of BCR-ABL1 values to the international scale. An automated cartridge-based assay (Xpert BCR-ABL Monitor(™), Cepheid) had been proposed as a robust alternative to non-automated assays. This study aimed to compare inter-laboratory reproducibility of automated and non-automated quantification, the possibility of converting automated results to the international scale, and the potential economic impact of automation. DESIGN AND METHODS: One hundred and eighteen blood samples from chronic myeloid leukemia patients treated with tyrosine kinase inhibitors were prospectively analyzed in two laboratories using both automated and non-automated assays. The economic evaluation involved a micro-costing study and average costs were assessed as a function of sample throughput. RESULTS: Automated assays achieved similar inter-laboratory reproducibility to highly standardized non-automated assays and a short delay (≤6 h) between sampling and blood lysis had a positive impact on inter-laboratory reproducibility. Reporting automated BCR-ABL1 ratios on the international scale was possible using a specific conversion factor which may vary with batches. Cost assessment showed that automated assays could be relevant for annual activity levels below 300 since average costs were lower than those of the non-automated assays. CONCLUSIONS: The Xpert BCR-ABL Monitor(™) assay could be appropriately used in a near-patient setting for routine quantification of e13/e14-a2 transcripts, preferably in partnership with a regional reference laboratory. However, its prognostic impact relative to non-automated quantification remains to be tested prospectively within appropriate clinical trials.

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 are key to explain these. METHODS: We elicit beliefs about the COVID-19 pandemic during lockdown in France by means of surveys asking French citizens about their belief of the infection fatality ratio (IFR) for COVID-19, own risk to catch the disease, risk as perceived by others, and expected prevalence rate. Those self-assessments were measured twice during lockdown: about 2 weeks after lockdown started and about 2 weeks before lockdown ended. We also measured the quality of these beliefs with respect to available evidence at the time of the surveys, allowing us to assess the calibration of beliefs based on risk-related socio-demographics. Finally, comparing own risk to expected prevalence rates in the two successive surveys provides a dynamic view of comparative optimism with respect to the disease. RESULTS: The risk perceptions are rather high in absolute terms and they increased between the two surveys. We found no evidence for an impact of personal experience with COVID-19 on beliefs and lower risk perceptions of the IFR when someone in the respondent's family has been diagnosed with a disease. Answers to survey 1 confirmed this pattern with a clear indication that respondents were optimistic about their chances to catch COVID-19. However, in survey 2, respondents revealed comparative pessimism. CONCLUSION: The results show that respondents overestimated the probabilities to catch or die from COVID-19, which is not unusual and does not necessarily reflect a strong deviation from rational behavior. While a rational model explains why the own risk to catch COVID-19 rose between the two surveys, it does not explain why the subjective assessment of the IFR remained stable. The comparative pessimism in survey 2 was likely due to a concomitant increase in the respondents' perceived chances to catch the disease and a decreased expected prevalence rate.
RESUMEN
INTRODUCTION: Rural areas are considered safe havens against the increased spread of COVID-19 and associated restrictive measures, especially in contexts where public authorities are not in a position to systematically and substantially ease COVID-19-induced economic shocks. In the current sub-Saharan Africa context, still marked by uncertainty surrounding the spread of COVID-19, we present the protocol of an ongoing longitudinal study aimed at investigating COVID-19-related attitudes, risks perceptions, preventive behaviours and economic impact in rural areas in Senegal. METHODS AND ANALYSIS: A prospective randomised longitudinal study of 600 households located in three semiurban villages and nine randomly selected rural villages in the Niakhar area (located 135 km East of Dakar). Three ad hoc phone surveys are administered to 600 heads of households, their housewives in charge of managing the household and a relative living temporarily in the household, respectively. In addition to sharing identical sets of questions on several topics (risks perceptions, attitudes to curfew, attitudes to vaccines, beliefs about COVID-19 infection), the three separate survey questionnaires also include other topics (economic impact, local preventive strategies) whose related questions differ between questionnaires. As analysing evolutions is the study's primary focus, data on all the topics covered will be collected in three waves unless the spread of COVID-19 by mid-2021 justifies extending data collection. The present article presents the study protocol and details about the implementation of the first wave of data collection which started in July 2020. The decision to wait before presenting the protocol was based on the unprecedented context the COVID-19 pandemic. ETHICS AND DISSEMINATION: The survey's protocol was approved by the Senegalese National Ethical Committee for Research in Health (131/MSAS/CNERS/Sec) and received authorisation from both the Senegalese Ministry of Health (619/MSAS/DPRS/DR) and the French Commission on Information Technology and Liberties (CNIL 2220771).

BACKGROUND: The contemporary crisis of trust in vaccines has severely impaired acceptance of the HPV vaccine, especially in France, where its uptake culminated at 23.7% in 2018 (complete course at age 16). Physicians' recommendations strongly influence its acceptance/refusal. Our study sought to understand the decision processes leading physicians to recommend this vaccine (or not). METHODS: Qualitative interviews of French physicians (general practitioners, gynecologists, and pediatricians). We first randomly selected doctors in a national register of medical professionals and then resorted to snowballing to build a convenience sample. We coded the interviews in a thematic analysis built both inductively and deductively from our research questions and data. RESULTS: Two thirds of the participants (19/28) were favorable to HPV vaccination, some (4) opposed it, while the others were hesitant about recommending it. In explaining their opinions, most participants mentioned that they trusted the stakeholders within the vaccination system: the less trust they had, the more critical they were of the vaccine and the more importance they attributed to patients' opinions. We identified three different ways they interacted with patients on this topic: informing and convincing; adapting to patients' opinions; refusing compromise about vaccination. Crossing these various themes, we found 5 types of physicians: dissidents (mistrustful of the healthcare system and HPV vaccine), hesitant (finding it difficult to make up their minds about this vaccination), laissez-faire (letting patients decide by themselves, but very favorable to HPV vaccination), educator (very favorable), and uncompromising vaccinators (refusing debate). Pediatricians were overrepresented among the latter two types. CONCLUSIONS: Physicians' judgment was influenced by their trust in the stakeholders involved in designing and implementing the HPV vaccination strategy. In this sense, doctors did not differ substantially from laypeople. They were, nonetheless, strongly influenced by their professional style and ethos.

Introduction: Intellectual Disability (ID) is the most common cause of referral to pediatric genetic centers, as it affects around 1-3% of the general population and is characterized by a wide genetic heterogeneity. The Genome Sequencing (GS) approach is expected to achieve a higher diagnostic yield than exome sequencing given its wider and more homogenous coverage, and, since theoretically, it can more accurately detect variations in regions traditionally not well captured and identify structural variants, or intergenic/deep intronic putatively pathological events. The decreasing cost of sequencing, the progress in data-management and bioinformatics, prompted us to assess GS efficiency as the first line procedure to identify the molecular diagnosis in patients without obvious ID etiology. This work is being carried out in the framework of the national French initiative for genomic medicine (Plan France Médecine Génomique 2025). Methods and Analysis: This multidisciplinary, prospective diagnostic study will compare the diagnostic yield of GS trio analysis (index case, father, mother) with the French core minimal reference strategy (Fragile-X testing, chromosomal microarray analysis and Gene Panel Strategy of 44 selected ID genes). Both strategies are applied in a blinded fashion, in parallel, in the same population of 1275 ID index cases with no obvious diagnosis (50% not previously investigated). Among them, a subgroup of 196 patients are randomized to undergo GS proband analysis in addition to GS trio analysis plus the French core minimal reference strategy, in order to compare their efficiency. The study also aims to identify the most appropriate strategy according to the clinical presentation of the patients, to evaluate the impact of deployment of GS on the families' diagnostic odyssey and the modification of their care, and to identify the advantages/difficulties for the patients and their families. Ethics Statement: The protocol was approved by the Ethics Committee Sud Méditerranée I and the French data privacy commission (CNIL, authorization 919361). Trial Registration: ClinicalTrials.gov identifier NCT04154891 (07/11/2019).
RESUMEN
OBJECTIVES: To investigate women's attitudes to successive decisions possibly involved in Down syndrome screening (i.e. about ultrasound and biochemical screening, invasive testing, and termination of pregnancy) and to compare attitudes and actual decisions. METHODS: Four hundred women were invited to complete a self-administered questionnaire within 3 days postpartum. A hierarchical cluster analysis identified respondents with similar attitudes, and logistic regressions assessed the effects of factors relating to decision-making on attitudes. RESULTS: Three hundred and ninety-one women returned the questionnaire. Three clusters of women were identified. Two clusters comprised respondents stating that decision-making should be based on attitudes to either termination of pregnancy (32.8%) or invasive testing-related miscarriage (30.2%). The third cluster (37.0%) considered that obtaining information about pregnancy should be the main objective when deciding about biochemical screening or invasive testing. Multivariate logistic regressions showed some consistency between attitudes and previous decisions. PRACTICE IMPLICATIONS: Providing information and eliciting women's attitudes towards the sequence of decisions possibly involved in Down syndrome screening could help them make their decisions about screening and/or invasive testing in line with their attitudes.

For more than a decade, doubt about vaccines has become an increasingly important global issue. Polarization of opinions on this matter, especially through social media, has been repeatedly observed, but details about the balance of forces are left unclear. In this paper, we analyse the flow of information on vaccines on the French-speaking realm of Twitter between 2016 and 2017. Two major asymmetries appear. Rather than opposing themselves on each vaccine, defenders and critics focus on different vaccines and vaccine-related topics. Pro-vaccine accounts focus on hopes for new groundbreaking vaccines and on ongoing outbreaks of vaccine-preventable illnesses. Vaccine critics concentrate their posts on a limited number of "controversial" vaccines and adjuvants. Furthermore, vaccine-critical accounts display greater craft and energy, using a wider variety of sources, and a more coordinated set of hashtags. This double asymmetry can have serious consequences. Despite the presence of a large number of pro-vaccine accounts, some arguments raised by efficiently organized and very active vaccine-critical activists are left unanswered.
RESUMEN
Introduction. Today, in Sub-Saharan Africa, vaccine-preventable diseases still contribute heavily to high child mortality. Maintaining high coverage rates for childhood vaccines and reducing related social inequalities are public health priorities in Senegal. Our aim was to investigate the determinants of childhood vaccination, including sociodemographic factors and previous vaccine-related decision-making.Methods. Data come from the 2016 Senegalese Demographic and Health Survey, a nationally representative household survey targeting women aged 15-49, with a questionnaire focusing on health and reproductive issues, including their children's health. We restricted the analysis to children aged 12-23 months (n = 1,143). We used bivariate and multivariate analyses for investigating the determinants of several childhood vaccinations (Bacillus Calmette-Guérin, pentavalent, polio, measles and yellow fever vaccines), including sociodemographic factors and previous shots.Results. We identified two main sociodemographic predictors of childhood vaccination in Senegal: the mother's education level, which was strongly and positively correlated to every vaccination considered, except from the BCG vaccination, and the region of residence, with higher vaccination coverage rates in the Centre and West of Senegal. Moreover, previous shots were also strongly predictive of subsequent shots.Conclusion. The positive impact of mother's education on child vaccination illustrates the wide-ranging benefits of educating girls, while the regional variability of immunization rates requires more research to be better understood. Previous shots are probably a proxy variable for unobservable factors strongly correlated to vaccinations, but beyond this 'proxy effect', they may also have their own specific effect on following shots. We believe this topic deserves further research.
