A vaccinologist says it's logical to roll out a new Omicron-fighting vaccine just in time for winter.
The bivalent jab, which combines two strains of the virus, will be available for anyone 30 plus from the start of April.
People already eligible for a booster will be able to get the new shot even earlier, from March.
University of Auckland vaccinologist Helen Petousis-Harris spoke to Corin Dann.
