Despite scientific evidence supporting the fact that vaccines are fundamental tools for preventing infectious diseases, a percentage of the population still refuses some or all of them. Vaccine hesitancy has become a widespread issue, and its complexity lies in the great variety of factors that can influence decisions about immunization, which are not just vaccine-related concerns, but also involve personal and societal levels. Our research group performed an extensive literature review to analyze: (1) different age groups, their relation to the problem and their characteristics; (2) the most important information (key messages) about immunization that could be used to counteract hesitancy; and (3) best approaches to transmit the messages to the target groups. We propose a long-term approach to overcome vaccine hesitancy that involves the education of children and adolescents on the basics about immunization and critical thinking, using different communication channels.
Equity and impact: Ontario’s infant rotavirus immunization program fiveyears following implementation. A population-based cohort study
The introduction of routine infant rotavirus immunization has had a substantial population impact in Ontario. Our study confirms herd effects and suggests the program may have reduced previous inequities in the burden of pediatric rotavirus hospitalizations.
This guidance was prepared by the Public Health Agency of Canada in consultation with the National Advisory Committee on Immunization and the Canadian Immunization Committee, and should be considered in concert with provincial and territorial policies on continuity of immunization programs during the COVID-19 pandemic, and as routine services begin to resume.
Involving stakeholders in informing the development of a Knowledge Translation (KT) intervention to improve the vaccination experience at school
Pain, fear, and fainting management during school-based vaccinations is suboptimal. The objective was to examine stakeholder perceptions of barriers and facilitators to better practices. Method: Six semi-structured focus groups were conducted in Niagara Region, Ontario: two parent groups (n=7); one grade 7 to 8 student group (n=9); two nurse groups (n=12); and one school staff group (n=6). Participants shared perceptions about school vaccination clinics and the implementation of specific strategies and tools. Focus groups were audio recorded and transcribed. The Consolidated Framework for Implementation Research (CFIR) was used as the framework for analysis.
Les maladies évitables par la vaccination : un aperçu des maladies peu fréquentes pour le professionnel de la santé de première ligne
Le présent point de pratique de la Société canadienne de pédiatrie fournit aux professionnels de la santé de première ligne un aperçu des maladies évitables par la vaccination qui, grâce au succès des programmes d’immunisation au Canada, sont devenues rares ou peu fréquentes. Les enfants et les adolescents du Canada et d’ailleurs peuvent encore contracter ces infections, dont le dépistage clinique a des conséquences importantes pour la santé publique. Afin d’offrir des soins préventifs, il est essentiel de connaître les signes et symptômes de ces maladies, de vacciner les voyageurs et les nouveaux arrivants au Canada, de connaître les éclosions dans la communauté et ailleurs et de consulter rapidement un expert en infectiologie et les services de santé publique pour les cas présumés.
Lignes directrices provisoires sur la continuité des programmes d’immunisation pendant la pandémie de COVID-19
Ces orientations ont été préparées par l’Agence de la santé publique du Canada en consultation avec le Comité consultatif national de l’immunisation et le Comité canadien sur l’immunisation, et devraient être prises en compte de concert avec les politiques provinciales et territoriales sur la continuité des programmes d’immunisation pendant la pandémie de COVID-19, et au moment où les services de vaccination systématique commencent à reprendre.
There is no scientific evidence that MMR vaccine causes autism. The question about a possible link between MMR vaccine and autism has been extensively reviewed by independent groups of experts in the United States, including the National Academy of Sciences’ Institute of Medicine (now renamed the National Academy of Medicine). These reviews have concluded that the available epidemiologic evidence does not support a causal link between MMR vaccine and autism
Overview of a Knowledge Translation (KT) Project to improve the vaccination experience at school: The CARD™ System
Students experience fear, pain, and fainting during vaccinations at school. While evidence-based interventions exist, no Knowledge Translation (KT) interventions have been developed to mitigate these symptoms. A multidisciplinary team—the Pain Pain Go Away Team—was assembled to address this knowledge-to-care gap. This manuscript provides an overview of the methodology, knowledge products, and impact of an evidence-based KT program developed and implemented to improve the vaccination experience at school.
Pertussis vaccine effectiveness in a frequency matched population-based case-control Canadian Immunization Research Network study in Ontario, Canada 2009–2015
Researchers estimated pertussis vaccine effectiveness through a case-control study of 1335 cases statutorily reported to public health in Ontario and occurring between January 1, 2009 and March 31, 2015, compared with 5340 randomly selected population controls, frequency-matched by age, primary-care provider and year of diagnosis. Pertussis cases met provincial confirmed or probable case definitions. Researchers used multivariable logistic regression to estimate crude and adjusted odds ratios.
Piloting The CARD™ System for education of students about vaccination: Does it improve the vaccination experience at school?
Many students are fearful of vaccine injection-associated pain. In prior research, we created Knowledge Translation (KT) tools to address school vaccinations and associated pain, fear, and fainting. The objectives of this pilot implementation project were to determine the acceptability and impact of these KT tools on student knowledge, attitudes, and perceptions of their vaccination experience.
