A number of countries around the world have done so and there are calls for New Zealand to follow suit. Kathryn speaks with Professor Michael Plank from the University of Canterbury, who has carried out initial modelling on what the omicron variant might mean. Also, Dr Fran Priddy is from the research group Vaccine Alliance Aotearoa.
