Adherencia a la campaña de vacunación de la gripe 2020/21 en el contexto de la pandemia de SARS-CoV-2. Análisis de los cambios en la gestión: un estudio piloto / Adherence to influenza vaccination campaign 2020/21 in the pandemic SARS-CoV-2. Context analysis in management changes: A pilot study

Introducción Las campañas de vacunación contra la gripe alcanzan coberturas por debajo de lo deseado y recomendado. Lo que en el contexto actual de pandemia por SARS-CoV-2 cobra mayor relevancia. Nuestro objetivo consiste en evaluar el impacto en la cobertura vacunal alcanzada de una serie de estrategias de implementación vacunal llevadas a cabo. Material y métodos Se introdujo una serie de estrategias de implementación de la vacunación en nuestra zona básica de salud como la captación activa y la ampliación horaria entre otras, se evaluó y comparó la cobertura vacunal alcanzada en la campaña actual con las previas, tanto a las 8 semanas como al final de la campaña. Además, se llevó a cabo un estudio transversal mediante una encuesta para valorar el impacto que habían tenido las medidas. Resultados En la semana 8 de la campaña detectamos diferencias significativas en cuanto al incremento de la cobertura vacunal alcanzada respecto a años previos, resultado que se confirmó al finalizar la campaña alcanzándose diferencias significativas (p<0,05) de cobertura vacunal en todos los centros estudiados, datos que fueron a favor de la efectividad de las estrategias empleadas. Conclusiones Las estrategias de implementación vacunal empleadas se han mostrado efectivas, logrando un incremento de hasta un 74% en las dosis totales administradas respecto a campañas previas y de hasta un 15% en la cobertura vacunal alcanzada en mayores de 64 años; pese al contexto de pandemia y al aumento de los movimientos antivacunas (AU)

Introduction Vaccination campaigns against influenza virus achieve coverages under recommended and desired values. In current context of SARS-CoV-2 pandemic it becomes more relevant. Our objective is to evaluate the impact on vaccination coverage of a set of implementation strategies carried out. Material and method Vaccine implementation strategies were introduced in our basic health zone as active caption of patients and schedule extension. Then the vaccination coverage achieved in the current campaign was evaluated and compared with previous in the 8th week and at the end of the campaign. Besides, a transversal study through a survey was carried out to measure the impact of the applied strategies. Result In the 8th week of the campaign significant differences were detected in the increase of vaccination coverage compared with previous years. These results were confirmed at the end of the campaign, getting a significant difference (<.05) of vaccination coverage in all the studied centers, these data support the effectivity of the applied strategies. Conclusions The vaccine implementation strategies applied have shown effectivity, achieving an increase of until 74% in the total administered doses compared to previous campaigns and even a 15% of vaccination coverage increased in the group of patients older than 64 years; even in a pandemic context and the increasing of anti-vaccine movements (AU)
