Vaccination coverage remains suboptimal in Canada and sporadic outbreaks of vaccine-preventable diseases such as measles and pertussis continue to occur. This study was undertaken to identify sociodemographic determinants of total non-vaccination (having never received any vaccine), non-vaccination for measles (0 doses) and incomplete vaccination for pertussis (< 4 doses) among 2-year-old Canadian children. Data from the 2013 Childhood National Immunization Coverage Survey (CNICS) were used. Associations between sociodemographic factors and outcomes were measured by multiple logistic regressions and adjusted odds ratios (aOR) were calculated. A total of 5,477 children were included in the analyses of total non-vaccination, and 3,899 children were included in the analysis of non-vaccination for measles and incomplete vaccination for pertussis. Overall, 2.7% of children (95% CI 2.0–3.3) had received no vaccine at all. Lower parental education, i.e., the responding parent having a high school diploma, trade certificate or less (compared with university graduation) was associated with total non-vaccination (aOR 1.99, 95% CI 1.02–3.91). Non-vaccination for measles was more frequent among children of single parent families (aOR 1.63, 95% CI 1.01–2.61) and those of parents with lower education (aOR 1.86, 95% CI 1.26–2.76). The odds of incomplete vaccination for pertussis was greater among children born outside Canada (aOR 3.10, 95% CI 1.73–5.58), of parents with lower education (aOR 1.92, 95% CI 1.41–2.62), and those whose household income was between $40,000 and $59,999 (aOR 1.47; 95% CI 1.04–2.07) or lower than $40,000 (aOR 1.58, 95% CI 1.13–2.22). Significant regional variation was also found for all outcomes. In conclusion, despite universal access to free childhood vaccines in Canada, regional variation and socioeconomic inequalities in vaccine uptake were still observed. Further analyses are warranted to identify barriers contributing to these variations.

It is important to listen carefully to the concerns parents raise regarding vaccines and autism. It is our job as medical and public health professionals to explain the science in a new way. The CASE method combines emotional and scientific talking points to sway parents' emotional responses and help them face the issue more logically.
Most vaccines protect both the vaccinated individual and the community at large by building up herd immunity. Even though reaching disease-specific herd immunity thresholds is crucial for eliminating or eradicating certain diseases, explanation of this concept remains rare in vaccine advocacy. An awareness of this social benefit makes vaccination not only an individual but also a social decision. Although knowledge of herd immunity can induce prosocial vaccination in order to protect others, it can also invite free-riding, in which individuals profit from the protection provided by a well-vaccinated society without contributing to herd immunity themselves. This cross-cultural experiment assesses whether people will be more or less likely to be vaccinated when they know more about herd immunity. Results show that in cultures that focus on collective benefits, vaccination willingness is generally higher. Communicating the concept of herd immunity improved willingness to vaccinate, especially in cultures lacking this prosocial cultural background. Prosocial nudges can thus help to close these immunity gaps.
This paper reports the findings of a national online survey to parents of children aged 5 and younger. The objectives of the study were to assess parental understanding of childhood immunizations, identify sources of information that they trust for vaccine-related content, assess where parents with young children stand on the key issues in the public debate about vaccination, and identify which risk communication messages are most effective for influencing the behaviours of vaccine hesitant parents.
Couverture vaccinale des adultes canadiens : résultats de l'Enquête nationale sur la vaccination des adultes de 2014
L’Enquête nationale sur la vaccination des adultes (ENVA) permet de mesurer la couverture vaccinale dans la population adulte au Canada et d’évaluer les progrès réalisés dans l'atteinte des cibles nationales. Le prochain cycle de l’ENVA aura lieu en 2016. L’Agence de la santé publique du Canada continuera à collaborer avec les provinces, les territoires et les autres intervenants afin d’améliorer les méthodes d’évaluation de la couverture vaccinale. L’éducation du public et des professionnels et les campagnes de sensibilisation continueront également de promouvoir les avantages et l’innocuité de l’immunisation au Canada.
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.
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.
