National Advisory Committee on Immunization (NACI): Statements and publications
NACI makes recommendations for the use of vaccines currently or newly approved for use in humans in Canada, including the identification of groups at risk for vaccine-preventable diseases for whom vaccination should be targeted. NACI knowledge syntheses, analyses and recommendations on vaccine use in Canada are published in literature reviews, statements and updates.
New statements are those which have been published within the past five years. Previous statements are those which are were published over five years ago and have been archived.
NACI recommendations are also published in vaccine-specific chapters of the Canadian Immunization Guide. Email updates are available through our mailing list.
