Hon CHRIS HIPKINS: The first and most important step is making sure that the shipment of vaccines that we have received is in good shape, it's arrived safely intact, and it's been kept at the correct temperature for the entire duration of its flight. During the course of the week, the vaccine will be tested for quality assurance—that's something that both the drug company and Medsafe are involved in. Once those safety checks are complete, doses are then formally released to start the first phase of the vaccination programme. This isn't necessarily a quick process, but it is important that we get it right; all of the quality control assurances have to be completed before the vaccines will start being used.
