Hon CHRIS HIPKINS (Minister for COVID-19 Response): The Government's already released the sequencing framework for the first group of people who are going to be getting the COVID-19 Pfizer vaccine in the first quarter of this year. That work is already under way. So it starts with our border workers, first and foremost. We're sitting somewhere about 90 percent of the way through doing that, having had the absolute latest numbers based on today's experiences. But, certainly, we're about 90 percent of the way through that, and we've made a start on their family and close contacts—you know, the household contacts of those people—and also on some of our front-line health workers. So the people who are involved in taking COVID-19 test swabs—those who are more at risk because they're on the front lines of the health services. So that's going to take us through the first quarter. We then start to move into the second quarter, where we're expecting a roughly equivalent number of people to be vaccinated—so around about another quarter of a million people in the second quarter. Then we'll get to the big roll-out in the second half of the year, and we're expecting that to be spread right the way through the second half of the year. There'll be surge points, no doubt, but we're expecting the overall demand—we will have to manage the demand relatively smoothly through the second half of the year. We'll be releasing details of that tomorrow. One of the reasons that we have not released that prior to now is the decision about which vaccine we used, and whether we used one vaccine or four different vaccines actually has an impact on the overall sequencing framework.
