Since 1997, the Immunisation Advisory Centre (IMAC) has been serving New Zealand with a local source of independent, factual information based on scientific research regarding vaccine-preventable diseases and the benefits and risks of immunisation. It has also been training New Zealand’s vaccinators for more than 15 years, providing information and training for health professionals, national immunisation coordination and policy advice and research into many aspects of vaccines and vaccine-preventable diseases. IMAC is operated by UniServices and based at the University of Auckland’s School of Population Health.
