Fact Check: "Alberta's measles outbreak is fueled by dangerously low vaccination rates."
What We Know
Recent data indicates that Alberta is experiencing a significant rise in measles cases, with vaccination rates among children being alarmingly low. According to a study published in 2025, measles vaccination coverage in Alberta can be as low as 32% in certain sub-populations, with typical rates ranging from 45% to 95% (source). This is concerning given that the recommended vaccination coverage to prevent outbreaks is at least 85%, and ideally above 95% (source).
The Public Health Agency of Canada (PHAC) has reported that vaccination uptake in Canada is below the target of 95% coverage necessary for measles elimination (source). Specifically, as of 2024, only 68.1% of two-year-olds in Alberta were up to date with their measles vaccinations (source). This low coverage is a critical factor contributing to the current outbreak, as measles is highly contagious and can spread rapidly in under-immunized communities.
Analysis
The claim that Alberta's measles outbreak is fueled by dangerously low vaccination rates is supported by multiple sources. The study indicates that outbreaks can occur in communities with vaccination rates below 85%, which aligns with the current situation in Alberta. The PHAC's assessment reinforces this by highlighting the insufficient vaccination coverage across the province.
Moreover, reports from local news outlets, such as the Calgary Herald, corroborate these findings by detailing the rise in measles cases and linking it directly to the low vaccination rates among children (source). The credibility of these sources is high, as they are based on peer-reviewed research and official public health assessments.
However, it is essential to note that while the data shows low vaccination rates, the specific reasons for these rates can vary, including vaccine hesitancy, misinformation, and lack of access to healthcare services. The variability in vaccination rates across different communities in Alberta suggests that targeted public health interventions are necessary to address these disparities.
Conclusion
The evidence strongly supports the claim that Alberta's measles outbreak is fueled by dangerously low vaccination rates. With vaccination coverage significantly below the recommended thresholds, the province is at heightened risk for outbreaks, particularly as measles cases continue to rise globally. Therefore, the verdict is True.
