According to the task force that coordinates the vaccination, users in this situation, and who have not yet been contacted by the health services, can "proactively go to the same Covid-19 vaccination centre (CVC) where they took the first dose" to receive the second dose.

In June, the Directorate General of Health (DGS) decided to reduce the interval for the second dose of Astrazeneca's vaccine from 12 to eight weeks to ensure "faster protection" against the transmission of new "variants of concern" of the SARS-CoV-2 virus.

In a statement, the Task Force said on 13 July that, "in order to accelerate the safety of all", it "reinforces this guidance" of the DGS and recalled that the schedules of the centres for this specific vaccination can be consulted at

The task force also recommended that, if the centre has a high number of people, which can be measured through the system of virtual traffic lights, users can choose to be vaccinated during the weekend, period "during which, in general, the waiting time has been lower".
