Hon CHRIS HIPKINS: I would note that most other countries are rationing booster doses to certain segments of their population. We've made the decision to make boosters available to everybody six months after their primary vaccine course was finished. Accordingly, most of this roll-out will happen naturally in 2020. That ensures simplicity and it also helps to ensure equity. Our focus will be on encouraging the most at risk of COVID, including our health workers, our border workers, and our Māori and Pacific communities. We'll also be making sure older people and our kaumātua, including people in aged residential care, have good access to booster doses when they become available. People don't necessarily need to rush to get this done. If you've been vaccinated, you're still very well protected from infection and from becoming seriously ill if you were to get COVID-19—Pfizer protection, for example, ranges from 85 to 93 percent in its effectiveness against severe disease, for hospitalisation it's is 80 percent - plus.
