Four million doses of the vaccine have been delivered so far. The quantities continue to go out at a much higher rate than we had ever envisaged was going to happen, and members opposite said it was never going to be possible. In fact, the people who are doing this work have exceeded expectations, and they deserve full thanks. So to everybody involved in the vaccination campaign, I want to say thank you. They have done sterling work. The criticism that has been levelled at them regularly since before the campaign even started has been wrong. They've proven it to be wrong, and they deserve to hold their heads high, knowing that they have delivered an exceptionally successful vaccine roll-out to date, and I know that they're going to keep doing that.
