RESUMO
OBJECTIVES: Pregnant women and new mothers are among the most vulnerable to seasonal influenza; however, little is known about their preferences for flu vaccination. We examined the rural-urban differences in uptake, demand and willingness to pay (WTP) for influenza vaccination among women of childbearing age, to assess the feasibility of implementing locally produced vaccines in Vietnam. METHODS: A cross-sectional study was performed in both urban and rural areas of Hanoi in 2018. Socio-demographic characteristics, history of vaccination, demand and WTP for influenza vaccines were obtained. A multivariate logistic regression model was employed to identify the associated factors. RESULTS: Of 750 participants, 29.9% had had flu shots in the current or previous flu season and 64.3% indicated demand for this vaccine. The median of the maximum amount of WTP for influenza vaccination services was US$ 8.5 (IQR: 8.5-17.0). Women living in rural areas had a significantly lower uptake and higher demand, and were willing to pay less than women in urban locations (21.1% vs. 36.6%; 69% vs. 60.2%; and US $8.5 vs. US $11.7, respectively). For urban participants, factors associated with higher demand and WTP for flu shots included having ANC in health facilities and having been vaccinated against influenza in the past; for rural women, these factors were having suffered from influenza and hearing about it. CONCLUSIONS: This study informs the feasibility of implementing locally produced influenza vaccines in Vietnam. Educational programs, along with counselling services and government subsidies, should be implemented to improve the coverage, demand and WTP for the vaccine.
OBJECTIFS: Les femmes enceintes et les nouvelles mères sont parmi les plus vulnérables à la grippe saisonnière; cependant, on en sait peu sur leurs préférences pour la vaccination contre la grippe. Nous avons examiné les différences entre les zones rurales et urbaines dans l'adoption, la demande et la volonté de payer pour la vaccination antigrippale chez les femmes en âge de procréer, afin d'évaluer la faisabilité de la mise en Åuvre de vaccins produits localement au Vietnam. MÉTHODES: Une étude transversale a été réalisée dans les zones urbaines et rurales de Hanoi en 2018. Les caractéristiques sociodémographiques, les antécédents de vaccination, la demande et la volonté de payer pour les vaccins antigrippaux ont été obtenus. Un modèle de régression logistique multivariée a été utilisé pour identifier les facteurs associés. RÉSULTATS: Sur 750 participantes, 29,9% s'étaient fait vacciner contre la grippe au cours de la saison grippale actuelle ou précédente, 64,3% ont indiqué une demande pour ce vaccin. La médiane du montant maximal de la volonté de payer pour les services de vaccination contre la grippe était de 8,5 USD (IQR: 8,5 à 17,0). Les femmes vivant dans les zones rurales avaient une adoption nettement plus faible, une demande plus élevée et étaient prêtes à payer moins que les femmes des zones urbaines (21,1% contre 36,6%; 69% contre 60,2%; et 8,5 USD contre 11,7 USD, respectivement). Pour les participantes urbaines, les facteurs associés à une demande plus élevée et à la volonté de payer pour les vaccins contre la grippe comprenaient le fait d'avoir des soins prénatals dans les établissements de santé et d'avoir été vaccinés contre la grippe dans le passé; pour les femmes rurales, ces facteurs comprenaient, avoir souffert de la grippe et en avoir entendu parler. CONCLUSIONS: Cette étude informe sur la faisabilité de la mise en Åuvre de vaccins antigrippaux produits localement au Vietnam. Des programmes éducatifs, ainsi que des services de conseil et des subventions gouvernementales devraient être mis en Åuvre pour améliorer la couverture, la demande et la volonté de payer pour le vaccin.

Tremendous progress has been made over the past three decades in the fight against the HIV epidemic; however, children experienced substantial physical and psychosocial effects of HIV infection. To inform services and policy development, we analyzed research growth and current trends in studies on children with HIV/AIDS. A total of 17,598 research papers and reviews in English, which were published on Web of Science, were downloaded. VOSviewer was used to generate an author keyword cooccurrence network and a network illustrating the connection among countries by shared coauthorships. Exploratory factor analysis was employed to identify research domains emerging from the abstracts' contents. The number of papers and their impacts had grown significantly in the past decade. The majority of study settings were in African countries. Research topics related to HIV in children were robust in areas of prevention of mother-to-child transmission and HIV and comorbidities treatments. Although psychosocial and behavioral disorders were recognized in previous studies, the number of interventions in these fields is still limited or not sustained. This study presents the global research trends and interests, points out research gaps of available publications and suggests several implications for services and intervention programs for children infected with HIV/AIDS. While preventions of mother-to-child transmission have been extensively studied, more efforts should be made to fulfill the lack of research on young people who are at risk of being infected or who are already infected with HIV. System thinking approach is needed in the design and implementation of future studies.
