Hon CHRIS HIPKINS: It will depend on the nature of the booster shots needed when they might be needed. I can say that from the conversations we've been having with Pfizer, I am confident that in the event that the evidence stacks up, supporting the need for a third shot of the Pfizer vaccine, we will be able to get access to that in a timely manner. But I also want to reiterate that we are not banking on that being the only option that New Zealand needs to have access to. We are in discussions with other pharmaceutical companies. Where agreements have been signed and it's appropriate to announce them, that's what we do.
