Hon CHRIS HIPKINS (Minister for COVID-19 Response): In terms of the overall effectiveness of vaccines, it's still early days yet, but what we're seeing around the world is that vaccination is still very effective against the Delta variant, although it could be slightly less effective than it is against some of the earlier variants of the virus. It still significantly reduces the chances of someone getting COVID-19, spreading COVID-19, and COVID-19 having a serious health effect on them, but it is, as I said, early days yet.
