Of course, what the regulatory impact statement also tells us is that under an Immediate Modification Order we could also potentially distribute the fourth dose. The Government's technical advisory committee is recommending New Zealanders therefore follow Singapore, the US, and Australia—to name but a few—and have a fourth vaccine. So what they're doing here is they're balancing off the need to protect the vulnerable—on evidence provided not by Pfizer to Medsafe in a Pfizer recommendation at this point, but on evidence from other organisations and other studies outside the Pfizer multi-cohort study they started in January—and the evidence there does seem to be suggesting that there's benefits to a fourth dose.
