1. Background

Influenza, also known as the flu, is a respiratory illness caused primarily by the influenza A and B viruses. It is one of the leading causes of death in Canada, averaging 12,200 hospitalizations and 3,500 deaths in Canada each year. Influenza activity is usually low in the spring and summer, begins to rise during the fall, and peaks in the winter months.

Everyday preventative actions such as frequent hand washing and covering coughs help to limit the spread of influenza. However, the most effective way to prevent the flu is by getting a yearly flu shot. The optimal time to receive the flu shot is in the fall before influenza begins spreading in the community.

Health Canada (HC) and the Public Health Agency of Canada (PHAC) ran the 2022-23 Seasonal Flu Vaccine Advertising Campaign from November 14, 2022, until January 13, 2023. The goal of the campaign was to raise awareness of the importance of the flu vaccine, particularly in high-risk groups, and to provide individuals with information to help them to self-identify as being at higher risk of complications from getting the flu. Another goal was to encourage people in close contact with high-risk populations to get a flu shot to protect themselves and those at high risk.

2. Research Objective

HC and PHAC are looking to assess the impact of its Seasonal Flu Advertising Campaign in raising awareness of the importance of getting a seasonal flu vaccine for at-risk populations and those in close contact with at-risk populations. This would be done with a post-campaign survey to see the effect of the communications intervention.

The objectives of the research are as follows:

The results of this research will allow HC and PHAC to evaluate the recall of this campaign.

The Government of Canada's Policy on Communications and Federal Identity requires the evaluation of all advertising campaigns exceeding $1 million in media through the Advertising Campaign Evaluation Tool (ACET).

Target Audience

The primary target audience is Canadians 18 years and older. The target audience for the campaign are four (4) at-risk and vulnerable groups of Canadians and people in close contact with these groups

  1. People at higher risk of flu-related complications, including:
  2. Adults aged 65 years and older
  3. Parents of children under 5 years of age
  4. People who are pregnant
  5. People in close contact with at-risk populations

3. Methodology

3.1 Online Sample

Respondents for the survey samples were drawn from a trusted partner panel vendor, Canadian Viewpoint Inc. The survey was conducted with a sample of n=2,306 Canadians ages 18+. Interviews were conducted in the language of their choice, either English or French.

A pre-test was launched on February 14, 2023, with 78 completes (56 English / 22 French). An open-ended question was asked at the end of the survey where any problems, questions, or unclear questions could be brought to our attention; no issues were flagged. The survey was fully launched and ran between February 15 and March 6, 2023.

Quotas were set to ensure representation by region, age, and gender, according to the latest Census information.

The sampling methodology utilized email invitations and router technology to invite participants. Each participant received a unique URL link. This link could only be used once, with respondents being allowed to pause during completion and return to complete. On average, the online interviews took 10 minutes to complete.

3.2 Participant Recruitment

Sample Source

Ipsos partnered with sub-contractor Canadian Viewpoint Inc. Canadian Viewpoint has one of the largest consumer panels with ~300,000 active panelists. Like Ipsos, Canadian Viewpoint uses mixed-medium strategies (phone/online/in-person) to build its panel to allow more representative samples. Canadian Viewpoint's online consumer panel is also recruited using post screeners during telephone surveys, Facebook, online vetted lists and in-person studies. Incentives were not used for recruitment purposes to ensure quality, but respondents were incentivized for completing the survey, which is directly proportionate to the amount of time taken to complete the survey and with comparable incentives offered by other online panel sources. We informed Health Canada and PHAC before we engaged with other approved panel vendors.

The comprehensive background profiling data were gathered when respondents joined the panel through screener questions, which allowed for the targeting of respondents based on key criteria, such as region, age, gender, education and income level, intention to buy a home within 12 months, profession, and other characteristics.

The online survey was conducted using Computer Assisted Web Interviewing (CAWI). Every panelist opted-in or chose to participate in research surveys. Panelists that meet the criteria we were looking for were randomly selected and sent an email invitation to complete the survey. Participants were offered a choice to complete the survey in either English or French.

The survey platform was Accessibility for Ontarians with Disabilities Act (AODA) compliant, according to Web Content Accessibility Guidelines (WCAG2.0AA).

Incentives and Quality Control Measures

Canadian Viewpoint use a multi-faceted approach to quality, integrating controls and best practices into every phase of the process. Panel members come from diverse fully certified sources. A dedicated team monitors performance by source using feedback loops and continuous reporting to prevent fraud. Our dedicated team monitors the panels for potentially fraudulent behavior, and blocks these people from ever entering a survey via safeguards that includes:

Sample Weighting

The table below shows the unweighted and weighted distributions of the online sample. Weighting was applied to the sample to ensure that the final data reflects the general adult population by region, age, and gender according to the 2021 Census. A Random Iterative Method (RIM) technique was applied for weighing.

Weighted and Unweighted Online Sample
Post-wave Survey
Unweighted Sample Size Weighted Sample Size
Canada 2306 2306
Region
British Columbia/Yukon 317 323
Alberta/Northwest Territories 257 254
Prairies (MB/SK)/ Nunavut 149 161
Ontario 892 876
Quebec 533 530
Atlantic Canada 158 161
Gender
Male 1127 1137
Female 1170 1160
Diverse 9 9
Age
18-24 234 252
25-34 374 368
35-44 375 365
45-54 418 409
55-64 420 410
65+ 485 501

The figures presented in the table above show minimal differences between the unweighted and weighted samples. As a result of the strong representativeness of the unweighted data the largest weight factor that was applied for any respondent is 1.08, which is well within acceptable ranges for a survey of the general population.

Email Statistics

For this survey, a sample router was used. Therefore, a response rate cannot be calculated. However, the participation rate for the post-wave survey was 91%. The participation rate is calculated as follows: (qualified completes + over quota + terminates)/click-through).

Completions Post-wave Survey
Click-Through 4250
- Partial Completes 383
- Terminates 662
- Over quota 893
Qualified Completes 2306
Participation Rate 91%

Non-Response Analysis

The results of this survey are not statistically projectable to the target population because the sampling method used does not ensure that the sample represents the target population with a known margin of sampling error. Reported percentages are not generalizable to any group other than the sample studied, and therefore no formal statistical inferences can be drawn between the sample results and the broader target population it may be intended to reflect. The data have been weighted to reflect the demographic composition of Canadian adults aged 18 years and over.

The table below compares the unweighted survey samples to the 2021 Census results by region, age, and gender. Overall, the sample is highly representative of the national adult population.

  Post-wave Survey
Unweighted Percentage Census 2021 Proportions

55-64 18% 18%
65+ 21% 24%

* Denotes variables included in the weighting scheme.

Differences among the variables used in the weighting scheme are minimal. The distribution in the sample is consistent, with only slight differences observed between the unweighted percentages and the 2021 Census data.
