The National Advisory Group on Immunisation (NAGI) was established in 1994 to bring together experts from different fields involved in vaccinology and immunisation to advise and guide the National Department of Health to implement an effective immunisation programme in keeping with current international standards and development.

The NAGI will provide the department with ongoing and timely medical, scientific and public health advice relating to vaccines and an immunisation strategy. This may relate to the use of new and established vaccines in humans, vaccine evaluation and the implementation of vaccine schedules in response to outbreaks or threats.
