Improving public health outcomes with subnational vaccination analysis
Our client’s vaccine product is included in the UK National Vaccination Programme and has a WHO set target to achieve herd immunity. They were feeling the impact of declining vaccination rates; for complex reasons, such as increased vaccine hesitancy and vaccine fatigue, vaccination coverage has not recovered since the pandemic.
Our client approached us with the challenge of identifying variation in subnational uptake and whether there were any population groups less inclined to be vaccinated, in order to refine their marketing efforts.
Understanding health inequalities and identifying disparities is crucial for developing targeted interventions and improving overall national vaccination rates.

We utilised population Open Data in our bespoke vaccination analysis
In addition to the vaccination coverage dataset our client had access to, we provided fresh ideas and complimentary datasets to expand insights.
We led a subnational analysis using population data by geography, deprivation and ethnicity to inform a market segmentation that identified local areas for the marketing team to focus on.
Using multiple, disparate datasets allowed us to yield additional insights not possible from the vaccination data alone.
CSL uncovered new insights in coverage variation across populations
Our experienced consultants were able to guide our client in how to best allocate their limited resources to have the biggest overall impact. CSL’s analysts introduced several new datasets to our client to establish new insights in their data, like a link between vaccination and main language spoken.
Additionally, we recommended marketing to a new population, that despite being historically small, had become sizeable due to declining vaccination rates and a change in the market dynamics.
CSL consolidated their analysis within a PowerPoint report with clear recommendations, strong visuals, and concise communication. This enabled our client to communicate the project findings to a wider internal team. Our findings were then used to inform marketing strategy for the client, including producing bespoke patient comms to address vaccination disparity in minority groups.
