 In 2002-2005, Canada introduced universal MenC programmes consisting of 1,2 or 3 infant doses. Most are one 12 mth dose. High rates of serogroupC disease in 2000 and 2001 prompted some provinces to launch universal MenC vaccination programmes in 2002. The goal was to provide protection in infancy and early childhood the time of most risk with the hope that the protection would extend throughout adolescence the second highest risk. It is unclear if early multi-dosing or 1 dose programmes would offer better protection lack of data. Each province in Canada has chosen different Meningococcal C Conjugate vaccine provision schedules for the primary vaccinations.
