Hi Dave.....it is only for over 70’s at moment. You can book through the Salud App or you can call in the Doctors in GA and they will make you an appointment. They are being carried out in Casa Del Mar in Santa Pola. You can have the flu jab at same time.....if you want it. It needs to have been at least 6 months since your 2nd vaccination.
As far as I am aware people are not being notified by phone/text as it was for original vaccination. It is up to the individual to arrange a booster.
Hope that helps..
