Dr GAURAV SHARMA (Labour—Hamilton West): It's a pleasure to speak on the Medicines Amendment Bill (No 2) today in the House. It was really good to hear from the other side some very cordial words, for the most part. I just want to say, first of all, that our vaccination programme has been one of the most leading in the world and has been applauded across the world, apart from by the Opposition on the other side. But the vaccination programme still continues, and, as Dr Reti said, there is emerging evidence that shows that having a fourth dose can make all the difference, especially to our vulnerable population. Studies in Israel and the UK have shown this, which is why Israel and Germany, as well as the UK, have looked into now having the fourth dose rolled out, which is what this bill is all about.
