Rt Hon JACINDA ARDERN: I think you'll see every country is trying to get their vaccination rates high enough that they can use a lower level of public health restrictions. I don't think I've seen anyone that is using nothing, though. Even Denmark, who many are referring to, does have very high vaccination rates across their total population, but is still using border controls. Businesses are still using what they call their corona pass. So I think you'd find very few places that are managing to keep hospitalisations low without using a coupling together of vaccinations and other measures, including their border measures.
