A harmonized immunization schedule for Canada: A call to action

In Canada, the National Advisory Committee on Immunization systematically reviews the evidence for the effectiveness and safety of new and old vaccines, and sets a 'minimum' recommended schedule. However, in contrast to other industrialized countries where single, harmonized countrywide immunization schedules are de rigeur, Canada has a confusing system, with each province and territory defining its own schedule - and none are the same. The time has come to rectify this decades-old patient equity and safety problem. The Canadian Paediatric Society calls for a harmonized schedule to improve the health and safety of Canadian children and youth.
