The advice given to people being vaccinated is that they should continue to wear masks, SD and so on.
From a public health perspective, this is absolutely the right advice to give, since the effect on transmission is as yet unproven. It is safer to be cautious.
There are also all kinds of ethical issues with privileging the vaccinated/penalising the unvaccinated, which is why the Government will try extremely hard to avoid it.
It will be masks/SD for all, until such time as the amount of virus in circulation is much, much lower. I expect restrictions to be reduced gradually, to assess the impact before moving further. It's not about how many people have been vaccinated, it's about the numbers of infections and hospitalisations. But actually it is about how many are vaccinated, because it will be that which is reducing the number of infections and hospitalisations as restrictions are removed. It's just we can't be sure yet how many we need to vaccinate - the target is uncertain.
As long as enough people DO get vaccinated, or have immunity through infection, we will reach the point where numbers stay sufficiently low without any restrictions. And normal life will resume.
But always - ALWAYS - being vigilant in case there is a new outbreak.
