How did Pfizer vaccine fare against Omicron in NZ?

New Zealand confronted Omicron as one of the most vaccinated populations on the planet – so what difference did that make in blunting the worst impacts? That's what researchers plan to find out in a new study exploring the effectiveness of multiple doses of the Pfizer vaccine against the variant, in what was also one of the world's few 'infection-naïve' populations. Study leaders Dr Anna Howe and Dr Matt Hobbs also aim to answer another critical question: what protection the vaccine gave Māori, Pasifika and other high-risk groups. By the time the Omicron outbreak forced the whole of New Zealand into the red traffic light setting on January 23, about 93 per cent of our eligible adult population – that's 3,910,251 people – had already received at least two doses of Pfizer's Comirnaty vaccine
