ABSTRACT
Introducción: La principal medida de prevención frente a la enfermedad meningocócica invasiva es la vacunación. El objetivo de este estudio es evaluar la aceptabilidad y las desigualdades socioeconómicas en el acceso a la vacuna frente a meningococo B (MenB) en la Comunidad de Madrid en el periodo previo a la introducción de la misma en el calendario. Materiales y métodos: Se realizó un estudio observacional descriptivo en la cohorte de niños/as nacidos entre 2016 y 2019, de tipo ecológico, empleando registros poblacionales electrónicos. Se describieron las coberturas de vacunación, se analizaron los factores asociados al estado vacunal, se describieron las distribuciones espaciales de cobertura de vacunación y de índice de privación (IP) y se analizó la asociación entre ambas mediante regresión espacial. Resultados: Se observó una tendencia creciente de las coberturas de primovacunación, pasando de un 44% en la cohorte de nacidos en el año 2016 a un 68% en la cohorte de 2019. Se encontró asociación estadísticamente significativa entre el estado vacunal y el IP (OR de primovacunación en zonas con IP5 respecto a zonas con IP1: 0,38; IC 95%: 0,39-0,50; p<0,001). El análisis espacial mostró correlación inversa entre el IP y la cobertura de vacunación. Conclusiones: El ascenso de las coberturas de esta vacuna muestra aceptación por parte de la población. La relación entre nivel socioeconómico y cobertura de vacunación confirma la existencia de una desigualdad en salud, y subraya la importancia de su inclusión en el calendario.(AU)
Introduction: The main preventive measure against invasive meningococcal disease is vaccination. The aim of our study was to evaluate the acceptability of the meningococcal B (MenB) vaccine and socioeconomic inequalities in the access to the vaccine in the Community of Madrid in the period prior to its introduction in the immunization schedule. Materials and methods: We conducted an observational and ecological descriptive study in the cohort of children born between 2016 and 2019 using population-based electronic records. We calculated the vaccination coverage and analysed factors associated with vaccination status, determined the spatial distribution of vaccination coverage and the deprivation index (DI) and assessed the association between them by means of spatial regression. Results: We observed an increasing trend in primary vaccination coverage, from 44% in the cohort born in 2016 to 68% in the 2019 cohort. We found a statistically significant association between vaccination status and the DI (OR of primary vaccination in areas with DI5 compared to areas with DP1, 0.38; 95% confidence interval: 0.39-0.50; P<.001). The spatial analysis showed an inverse correlation between the DI and vaccination coverage. Conclusions: The rise in the coverages of the MenB vaccine shows acceptance by the population. The association between socioeconomic level and vaccination coverage confirms the existence of health inequality and underlines the importance including this vaccine in the immunization schedule.(AU)

BACKGROUND: Reaching the public health organizations targets of influenza vaccination in at-risk patient groups remains a challenge worldwide. Recognizing the relationship between the healthcare system characteristics and the economic environment of the population with vaccination uptake can be of great importance to improve. METHODS: Several characteristics were correlated in this retrospective ecological study with data from 6.8 million citizens, 15,812 healthcare workers across 258 primary care health centers, and average income by area of the care center in Spain. RESULTS: No correlation between HCW vaccination status and patient vaccination was found. A weak negative significant correlation between the size of the population the care center covers and their vaccination status did exist (6 mo.-59 yr., r = 0.19, p = 0.002; 60-64 yr., r = 0.23, p < 0.001; ≥65 yr., r = 0.23, p ≥ 0.001). The primary care centers with fewer HCWs had better uptake in the at-risk groups in the age groups of 60-64 yr. (r = 0.20, p = 0.002) and ≥65 (r = 0.023, p ≥ 0.001). A negative correlation was found regarding workload in the 6 mo.-59 yr. age group (r = 0.18, p = 0.004), which showed the at-risk groups that lived in the most economically deprived areas were more likely to be vaccinated. CONCLUSIONS: This study reveals that the confounding variables that determine influenza vaccination in a population and in HCWs are complex. Future influenza campaigns should address these especially considering the possibility of combining influenza and SARS-CoV-2 vaccines each year.
ABSTRACT
INTRODUCTION: Influenza vaccination campaigns have difficulty in reaching the 75% uptake in healthcare workers (HCWs) that public health organizations target. This study runs a campaign across 42 primary care centers (PCCs) where for every HCW vaccinated against influenza, a polio vaccine is donated through UNICEF for children in developing nations. It also analyses the efficacy and cost of the campaign. METHOD: This observational prospective non-randomized cohort study was conducted across 262 PCCs and 15.812 HCWs. A total of 42 PCCs were delivered the full campaign, 114 were used as the control group, and 106 were excluded. The vaccine uptake in HCWs within each of those PCCs was registered. The cost analysis assumes that campaign costs remain stable year to year, and the only added cost would be the polio vaccines (0.59). RESULTS: We found statistically significant differences between both groups. A total of 1423 (59.02%) HCWs got vaccinated in the intervention group and 3768 (55.76%) in the control group OR 1.14, CI 95% (1.04-1.26). In this scenario, each additional HCW vaccinated in the intervention group costs 10.67. Assuming all 262 PCCs had joined the campaign and reached 59.02% uptake, the cost of running this incentive would have been 5506. The potential cost of increasing uptake in HCWs by 1% across all PCC (n = 8816) would be 1683, and across all healthcare providers, 8862 (n = 83.226). CONCLUSIONS: This study reveals that influenza vaccination uptake can be innovative by including solidary incentives and be successful in increasing uptake in HCWs. The cost of running a campaign such as this one is low.
ABSTRACT
Introducción: La vacunación antigripal está especialmente indicada en población infantil con riesgo de complicaciones o enfermedad grave. El objetivo de este estudio es describir el porcentaje de vacunación frente a la gripe en menores de 15 años con condiciones de riesgo en la Comunidad de Madrid, así como analizar los factores asociados a la adherencia vacunal a lo largo de tres campañas de vacunación. Material y métodos: Estudio observacional, transversal, de base poblacional de niños/as de seis meses a 14 años y con condiciones de riesgo que tuvieran indicación de vacunación antigripal al inicio de la campaña 2018-2019. Se emplearon registros poblacionales electrónicos. Se describió el porcentaje de vacunados durante tres campañas consecutivas. Se analizó mediante análisis bivariado y multivariado la asociación de la adherencia vacunal con variables demográficas, socioeconómicas y condiciones de riesgo. Resultados: La cobertura vacunal fue del 15,6% en la campaña 2018-2019. La adherencia a la vacunación fue del 65,9%. Se asociaron a una mayor adherencia edad ≥ 3 años, fundamentalmente de 6-10 años (ORa=1,63; IC 95% [1,43-1,85]) y presentar más de una condición de riesgo, especialmente ≥ 3 (ORa=1,80; IC 95% [1,00-3,26]). La enfermedad más asociada fue diabetes mellitus (ORa=2,15; IC 95% [1,74-2,65]). Las personas extranjeras presentaron menor adherencia (ORa=0,43; IC 95% [0,36-0,51]). No se encontraron diferencias en la adherencia según sexo ni nivel socioeconómico. Conclusiones: La adherencia y cobertura vacunal se encuentran en niveles subóptimos. La adherencia a la vacunación antigripal se asocia a características demográficas y clínicas. Es necesario establecer estrategias para incrementar la vacunación en población infantil, con mayor implicación de profesionales y formación de progenitores. (AU)
Introduction: Vaccination against influenza is indicated in children at risk of complications or severe disease. The objective of this study was to describe the percentage of children aged less than 15 years with risk conditions vaccinated against influenza in the Community of Madrid, and to analyze the factors associated with adherence to vaccination throughout 3 vaccination campaigns. Materials and methods: Population-based cross-sectional observational study of children aged 6 months to 14 years with conditions that indicated influenza vaccination at the beginning of the 20182019 campaign. Electronic population registers were used. We described the percentage of children vaccinated in 3 consecutive campaigns, and assessed the association of adherence to vaccination with demographic and socioeconomic variables and risk conditions using bivariate and multivariate analysis. Results: The vaccination coverage was 15.6% in the 20182019 campaign. The adherence to vaccination was 65.9%. The variables associated with greater adherence were age greater than 2 years, especially in the 610 years group (aOR=1.63; 95% CI: 1.431.85) and presenting more than one risk condition, especially 3 or more diseases (aOR=1.80; 95% CI: 1.003.26). Diabetes mellitus was the disease associated most strongly with adherence (aOR=2.15; 95% CI: 1.742.65). Adherence was lower in the immigrant population (aOR=0.43; 95% CI: 0.360.51). We found no association between vaccination adherence and sex or socioeconomic status. Conclusions: Vaccination coverage and adherence were suboptimal. Adherence to vaccination against influenza is associated with demographic and clinical conditions. Strategies need to be established to increase vaccination in children, with greater involvement of professionals and education of parents. (AU)

OBJECTIVE: It is important to know the impact of public financing on routine vaccination on compliance with the vaccination regimen. Few studies have been carried out on this topic. The objective of this study was to describe the effect of public financing of pneumococcal vaccine on vaccination coverage and the degree of compliance with the vaccination regimen in the child population of the Community of Madrid (CM). METHODS: A descriptive observational study was carried out. The study population were children vaccinated in the period of public (2008 and 2010) and private (2012 and 2013) funding. Data source was the vaccination information system. We estimated the coverage of "full inmunization" at 24 months and the coverage of "vaccination on time" of the primary vaccination and the complete schedule. Comparison according to the type of financing was made using the prevalence ratio (PR) and the relative percentage of change. The delay between vaccine doses was calculated at 24 months of age. RESULTS: On-time vaccination coverage was 72% when public financing of the vaccine and 64% when private financing (PR= 1.12). The delay between doses was greater than 10% when funding was private. CONCLUSIONS: Public financing of the vaccine improves compliance with the vaccine regimen.
OBJETIVO: Es importante conocer el impacto de la financiación pública de la vacunación sistemática sobre el cumplimiento de la pauta vacunal. Se han realizado pocos estudios sobre este tema. El objetivo de este estudio fue describir el efecto de la financiación pública de la vacuna antineumocócica sobre la cobertura de vacunación y el grado de cumplimiento de la pauta vacunal en la población infantil de la Comunidad de Madrid (CM). METODOS: Se realizó un estudio observacional descriptivo. La población de estudio fueron niños residentes en la Comunidad de Madrid que alcanzaron la edad de vacunación en los períodos de financiación pública (2008 y 2010) y privada (2012 y 2013). La fuente de datos fue el sistema de información vacunal de la CM. Se estimó la cobertura de "vacunación completa" a los 24 meses y la cobertura de "vacunación a tiempo" de la primovacunación y de la pauta completa. La comparación según el tipo de financiación se efectuó mediante la razón de prevalencias (RP) y el porcentaje relativo del cambio. Se calculó el retraso entre dosis vacunales a los veinticuatro meses de edad. RESULTADOS: La cobertura de vacunación a tiempo fue del 72% cuando la financiación de la vacuna fue pública y del 64% cuando fue privada (RP=1,12). El retraso entre dosis fue mayor del 10% cuando la financiación fue privada. CONCLUSIONES: La financiación pública de la vacuna mejora el cumplimiento de la pauta vacunal.

OBJECTIVE: In 2019 the Interterritorial Board of the Spanish National Health System approved the modification of the vaccination strategy against meningococcus. The objective of this study was to evaluate the meningococcal ACWY catch-up vaccination program in adolescents born in 2001 and 2002 in the Community of Madrid. METHODS: Cross-sectional population-based study. Vaccine coverage was estimated and factors associated with vaccination were assessed using logistic regression models. RESULTS: Vaccination coverage was 57.1% for those born in 2001 and 51.9% for those born in 2002. The probability of vaccination was higher in women (ORa=1.18), adolescents with chronic conditions (ORa=1.38), residents in rural areas (ORa=1.76) and in areas with lower socioeconomic level. Being born in 2002 (ORa=0.78) and abroad (ORa=0.35) were associated with a lower probability of vaccination. CONCLUSIONS: Coverage is high compared to similar campaigns in other settings, although there is significant room for improvement, so our study can contribute to the design of strategies to optimize results.
OBJETIVO: En 2019, el Consejo Interterritorial del Sistema Nacional de Salud aprobó la modificación de la estrategia de vacunación frente a meningococo. El objetivo de este estudio fue evaluar la vacunación de rescate frente a meningococo A, C, W, Y en adolescentes nacidos en 2001 y 2002 en la Comunidad de Madrid. METODOS: Se realizó un estudio transversal de base poblacional. Se determinó la cobertura vacunal y los factores asociados a la vacunación, utilizando modelos de regresión logística. RESULTADOS: La cobertura vacunal fue del 57,1% para nacidos en 2001 y del 51,9% para nacidos en 2002. La probabilidad de vacunación fue mayor en mujeres (ORa=1,18), adolescentes con alguna enfermedad crónica (ORa=1,38), residentes en el ámbito rural (ORa=1,76) y en zonas con menor nivel socioeconómico. Haber nacido en 2002 (ORa=0,78) y en el extranjero (ORa=0,35) se asociaron a una menor probabilidad de vacunación. CONCLUSIONES: La cobertura es elevada en comparación con campañas similares en otros entornos, aunque existe un importante margen de mejora, por lo que nuestro estudio puede contribuir al diseño de estrategias para optimizar los resultados.
