Vaccination isn't a binary state. Protection wanes over time. I don't know where to get the data, but I'd guess that most people in Gibraltar have been vaccinated quite a while ago.
Maybe we need tighter schedules, i.e. one shot every two months? With delta, i think that's when effectiveness starts to wane.
