Vaccinations have made a negligible contribution to reducing R so far. That may start to change but so far it's just the lockdown that's keeping R low.
My understanding of the jabs, is that it will only stop/reduce the symptoms - it will not stop you getting the covid, nor stop you passing it on to others. Or at least that is what they are saying for the moment, so why will having the jab, from others point of view, make it possible for you to then have a holiday?
Like the wearing of masks - it is mostly to prevent you spreading your germs to others you come into contact with.
