There's a couple of issues I want to canvass in my contribution. The first is in relation to the scientific background and the COVID-19 Vaccine Technical Advisory Group, or CV TAG, as they've become known in the vernacular amongst the panoply of advisory groups that assist the Government in relation to COVID, has recommended that people aged over 65, Māori and Pacific peoples aged over 50 years, people in aged residential care, and the severely immunocompromised should receive a fourth dose of the Pfizer vaccine, the Comirnaty Pfizer vaccine, before winter 2022, and many other countries have already moved to do that. We support the provision of the fourth dose to the groups that the Minister has outlined and that the regulatory impact statement for this bill provides for, and we support the provision of the money in Budget 2022—it's quite a considerable sum of money—to provide that.
