New modelling from Te Pūnaha Matatini reveals that Herd immunity appears unachievable in New Zealand, Stuff reports. The new modelling shows 97 per cent of the population needs to be vaccinated to stop the spread of new Covid-19 variants. Meanwhile, hospitalisations and deaths from Covid-19 would “massively reduce” once 75 to 80 percent of the population was vaccinated. The latest regular polling of New Zealanders’ attitude towards vaccines found 77 per cent of eligible Kiwis have either already been vaccinated or were likely to.
