Rt Hon JACINDA ARDERN: Firstly, that New Zealand will have not just one vaccine. There will be many. Some will be more appropriate for different parts of the population than others. That the first arrivals are likely to be smaller numbers of doses, and that we'll need to sequence the distribution of those for those who are in higher-risk areas of work. Secondly, that as data across the globe is provided, we'll be able to see whether or not the vaccine also reduces the amount of transmission. That will help us know whether or not, for instance, a vaccinated traveller bears risk to New Zealand or not. And, thirdly, that we are doing everything we can to make sure that we can provide a safe vaccine, when it's available, to all New Zealanders for free.
