Mr. Stephen Mulvany:

Yes, what is happening is, as the different strains of the virus change, the clinical advice that comes from the Department and the Chief Medical Officer and the advice they take changes. We have vaccines, and as newer versions of those vaccines come out, it is always the preference that the most potent vaccine that is appropriate for people's health is applied. That means we end up having vaccines which were contractually bought and paid for which are not yet obsolete but they will never be used because the clinical advice has moved on to say this is a better version for what people are experiencing now, and that always takes precedence. Therefore, this contract takes us up to the end of 2026 and the assumption is something else will be negotiated before we get to that point. We will continue to need vaccines-----
