Challenges and opportunities of school-based HPV vaccination in Canada.

Primary prevention of human papillomavirus (HPV) through vaccination is a high priority in Canada's cancer prevention efforts. All Canadian provinces and territories have introduced publicly funded, school-based vaccination programs against HPV, but vaccine uptake remains suboptimal in some jurisdictions. We conducted a descriptive qualitative study to better understand the determinants of low HPV vaccine uptake and identify strategies to enhance vaccine acceptance using the socio-ecological model.

Impact of vaccine delays at the 2, 4, 6 and 12 month visits on incomplete vaccination status by 24 months of age in Quebec, Canada.

Background: Timeliness in the administration of recommended vaccines is often evaluated using vaccine delays and provides more information regarding the susceptibility of children to vaccine-preventable diseases compared with vaccine coverage at a given age. The importance of on-time administration of vaccines scheduled at the first visit is well documented, but data are scarce about the impact of vaccine delays at other visits on vaccination status by 24 months of age. Using vaccine delays for the first three doses of DTaP-containing vaccines and for the first dose of measles-containing vaccines as markers of timeliness at the 2, 4, 6 and 12 month visits, we estimated the proportion of incomplete vaccination status by 24 months of age attributable to a vaccine delay at each of these visits.

The aim of this study was to assess Canadian maternity care providers' knowledge, attitudes, and practices regarding influenza vaccination in pregnancy.

Impact of the addition of new vaccines in the early childhood schedule on vaccine coverage by 24 months of age from 2006 to 2016 in Quebec, Canada.

Context: Between 2004 and 2016, in the province of Quebec (Canada), 4 new antigens were added in the early childhood vaccine schedule from birth to 18 months, increasing the number of injections or doses needed from 7 to 12. These additions may have decreased the proportion of children who had received all recommended vaccines.

Objectives: To assess the impact of the introduction of new vaccines to the childhood schedule on the 24-month vaccine coverage from 2006 to 2016 and identify factors associated with incomplete vaccination status by 24 months of age.

Determinants of influenza vaccination among a large adult population in Quebec.

Objectives: Very low uptake has been noted for influenza vaccination in the province of Quebec. This study aimed to identify the determinants of influenza vaccination among a large regional population.

Promoting advance care planning among community-based older adults: A randomized controlled trial.

Objective: To test an intervention designed to motivate older adults in documenting their healthcare preferences in advance, and to guide proxies in making hypothetical decisions that match those of the older adult.

Methods: The trial involved 235 older adults, of which half were assisted in communicating their wishes to their proxy. Hypothetical vignettes were used at baseline and twice after the intervention to elicit older adults' preferences and assess their proxy's ability to predict them.

Understanding Vaccine Hesitancy in Canada: Results of a Consultation Study by the Canadian Immunization Research Network.

"Vaccine hesitancy" is a concept now frequently used in vaccination discourse. The increased popularity of this concept in both academic and public health circles is challenging previously held perspectives that individual vaccination attitudes and behaviours are a simple dichotomy of accept or reject. A consultation study was designed to assess the opinions of experts and health professionals concerning the definition, scope, and causes of vaccine hesitancy in Canada.

Cost-effectiveness analysis of antiviral treatment in the management of seasonal influenza A: point-of-care rapid test versus clinical judgment.

Background: A point-of-care rapid test (POCRT) may help early and targeted use of antiviral drugs for the management of influenza A infection.

Objective: (i) To determine whether antiviral treatment based on a POCRT for influenza A is cost-effective and, (ii) to determine the thresholds of key test parameters (sensitivity, specificity and cost) at which a POCRT based-strategy appears to be cost effective.

Methods: An hybrid « susceptible, infected, recovered (SIR) » compartmental transmission and Markov decision analytic model was used to simulate the cost-effectiveness of antiviral treatment based on a POCRT for influenza A in the social perspective.
