Vaccine Hesitancy in Canada: SFU Study Points to Systemic Barriers | SFU Research

The narrative around vaccine hesitancy often focuses on individual beliefs and choices. But a new study from Simon Fraser University (SFU) challenges that assumption, suggesting that systemic barriers—cultural, administrative, institutional, and governance-related—play a far more significant role in creating vaccine gaps in Canada. Published in the journal Vaccine, the research highlights how these structural forces can reinforce mistrust and limit equitable access to vaccination, even among individuals who aren’t necessarily opposed to vaccines.

Beyond Personal Choice: Mapping the Barriers

The SFU study, led by health sciences researcher Haaris Tiwana, analyzed 41 peer-reviewed papers to identify the ways in which these barriers manifest. Researchers found that top-down decision-making processes, a lack of transparency, and inconsistent messaging from authorities can erode public trust in vaccines and the healthcare system. This is particularly relevant given the rapid pace of vaccine development and deployment during the COVID-19 pandemic, where evolving information and shifting recommendations were common. Mirage News reports on the study’s findings.

The study as well points to deficiencies in data collection and analysis. A lack of race-based data, for example, hinders the ability to identify and address specific barriers faced by marginalized communities. Without this granular data, targeted interventions are difficult to design and implement effectively. Rigid bureaucratic processes, staffing shortages, and inconvenient clinic hours can create practical obstacles to access, particularly for individuals with limited time or resources.

Cultural Context and Mistrust

Cultural mistrust, religious concerns, and prevailing social norms were identified as strong influences on vaccine attitudes. These factors aren’t simply individual preferences; they are deeply embedded within communities and often stem from historical experiences of discrimination and marginalization. As Tiwana explains, “It’s an uncomplicated narrative to say someone just chooses not to get vaccinated, but that’s unfair and incomplete.” He uses the example of a single mother working full-time who may be unable to attend a clinic with limited operating hours. WNC details this perspective.

The study emphasizes that these aren’t individual failings, but rather systemic issues that create inequitable access. Someone without a family doctor might turn to online sources for information, potentially encountering misinformation. Individuals who require translation services may rely on community members who aren’t necessarily well-informed. These scenarios illustrate how structural barriers can prevent people from making informed decisions about their health.

The Role of Homophily and Community Dynamics

Related research from Simon Fraser University, highlighted by SFU Research Performance & Excellence, adds another layer to this understanding. The concept of “homophily”—the tendency for people with similar views to associate with each other—can lead to the formation of clusters of unvaccinated individuals. This can reduce the overall effectiveness of vaccines within communities, as the virus can more easily spread among those who are not protected.

What the Study Doesn’t Tell Us

Whereas the SFU study provides valuable insights into the structural barriers to vaccination, it’s important to acknowledge its limitations. The analysis of existing research may be subject to publication bias, meaning that studies showing a link between structural barriers and vaccine hesitancy may be more likely to be published than those that do not. The study focuses specifically on the Canadian context, and the findings may not be generalizable to other countries with different healthcare systems and cultural norms. The study does not attempt to quantify the relative contribution of each barrier, making it difficult to prioritize interventions.

Implications for Public Health Strategies

The findings of this study have significant implications for public health strategies. Simply providing information about the benefits of vaccines is unlikely to be sufficient to overcome the barriers identified by the researchers. Instead, a more comprehensive approach is needed that addresses the underlying structural issues. This includes removing identification requirements, providing culturally safe and anti-racist vaccine delivery services, and investing in peer- and community-led vaccination models.

The study suggests that peer- and community-led models can improve access, but these initiatives often lack stable funding. Addressing this funding gap is crucial to ensuring the sustainability of these programs. Improving data systems and collecting race-based data are essential for identifying and addressing disparities in vaccine uptake.

Looking Ahead: Process and Surveillance

The study’s findings are likely to inform ongoing reviews of vaccination programs and policies. Public health agencies will need to consider how to incorporate the identified barriers into their planning and implementation efforts. Continued surveillance of vaccine uptake rates, particularly within marginalized communities, will be essential for monitoring progress and identifying emerging challenges. The World Health Organization (WHO) provides guidance on vaccine hesitancy and strategies to address it, emphasizing the importance of building trust and engaging with communities. WHO Q&A on Vaccine Hesitancy offers further context.

addressing vaccine gaps requires a shift in perspective—from viewing hesitancy as a purely individual choice to recognizing it as a complex issue shaped by systemic forces. By dismantling these barriers and promoting equitable access to vaccines, You can create healthier and more resilient communities.
