This amendment bill does a very simple thing. It gives the Director-General of Health the power to make an appropriate order to make a vaccine otherwise not available, available for widespread use. The background to this is, of course, COVID 19, and we have a recognised vaccine, the Comirnaty vaccine produced by Pfizer. Pfizer applied for and obtained from Pharmac approval for the use of that vaccine in accordance with the terms applied for by Pfizer, and that allowed the vaccine to be administered within New Zealand to a number of New Zealanders over a certain age, and a certain number of doses certain periods apart. It is clear from information available that this vaccine, like most vaccines, has a waning efficacy and, as many other countries have found, we wanted to make sure that particularly vulnerable parts of our population continued to get access to the vaccine while COVID remains a real risk.
