Introduction: Vaccination campaigns against influenza virus achieve coverages under recom-mended 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 methods: Vaccine implementation strategies were introduced in our basic health zone as active caption of patients and schedule extension. Then the vaccination coverage achie-ved in the current campaign was evaluated and compared with previous in the 8 th 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. Results: In the 8 th 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.
