Vaccine coverage in Canadian children: Highlights from the 2013 childhood National Immunization Coverage Survey (cNICS)

The 2013 Childhood National Immunization Coverage Survey (cNICS) is the largest national-level immunization coverage survey ever carried out in Canada. Results from the survey showed that the majority of Canadian children are immunized against vaccine-preventable diseases, but there is room to improve in keeping vaccinations up to date.

Vaccine uptake in Canadian adults: results from the 2014 adult National Immunization Coverage Survey

The Adult National Immunization Coverage Survey (aNICS) constitutes an ongoing approach to measuring adult immunization coverage in Canada and monitoring progress towards national targets. The next aNICS cycle will take place in 2016. The Public Health Agency of Canada will continue to work to collaborate with provinces, territories and other stakeholders to improve immunization coverage assessment methodology. Public and professional education and outreach campaigns will also continue to promote the benefits and safety of immunization in Canada.

Immunization surveillance, assessment and monitoring

WHO’s Immunization Vaccines and Biologicals’ focus is to monitor and assess the impact of strategies and activities for reducing morbidity and mortality of vaccine-preventable diseases. Collection, analysis and interpretation of surveillance data is vital to guide vaccination policies and programmes and ensure immunization targets are being reached.

Approved but non-funded vaccines: Accessing individual protection

Funded immunization programs are best able to achieve high participation rates, optimal protection of the target population, and indirect protection of others. However, in many countries public funding of approved vaccines can be substantially delayed, limited to a portion of the at-risk population or denied altogether. In these situations, unfunded vaccines are often inaccessible to individuals at risk, allowing potentially avoidable morbidity and mortality to continue to occur. The authors contend that private access to approved but unfunded vaccines should be reconsidered and encouraged, with recognition that individuals have a prerogative to take advantage of a vaccine of potential benefit to them whether it is publicly funded or not. Moreover, numbers of “approved but unfunded” vaccines are likely to grow because governments will not be able to fund all future vaccines of potential benefit to some citizens. New strategies are needed to better use unfunded vaccines even though the net benefits will fall short of those of funded programs.

Couverture vaccinale des adultes au Canada : Résultats de l'Enquête nationale sur la vaccination des adultes (ENVA) de 2012

Depuis 2001, l'Agence de la santé publique du Canada (l'Agence) évalue régulièrement le taux de couverture vaccinale des adultes à l'échelle nationale pour certains vaccins au moyen de l'Enquête nationale sur la vaccination des adultes (ENVA). Les résultats de ces enquêtes sont utilisés pour évaluer les progrès réalisés en vue d'atteindre les cibles de couverture vaccinale à l'échelle nationale, rendre compte des données estimatives de couverture vaccinale aux organismes internationaux, améliorer la planification de la préparation en cas de pandémie de grippe et mettre au point des stratégies ciblées et pertinentes de sensibilisation du public.

Vaccine coverage amongst adult Canadians: Results from the 2012 adult National Immunization Coverage (aNIC) survey

Since 2001, the Public Health Agency of Canada (the Agency) routinely monitors national immunization coverage for select adult immunizations through the adult National Immunization Coverage Survey (aNICS). Results from these surveys are used to monitor progress towards national targets for immunization coverage, to report immunization coverage estimates to international organizations, to improve planning for pandemic influenza and to develop appropriately targeted public education strategies.
