1. Summary

Leger is pleased to submit this methodological report to the Public Health Agency of Canada (PHAC) of a quantitative survey assessing seasonal influenza vaccination coverage among the Canadian population.

This report was prepared by Leger following the awarding of a contract to PHAC (contract number 6D034-214802/001/CY, awarded December 8th, 2021. This contract has a value of $248,836.74 (including HST).

1.1 Background and Objectives

For several years now, PHAC has been conducting a study at the beginning of the year on the uptake of seasonal influenza vaccination in the Canadian population. This study has multiple research objectives. The survey covers a variety of elements and topics. This year, some secondary objectives were added to the study while other items covered in previous years were removed from the study.

The primary objective of the research was to provide national vaccination coverage estimates for the seasonal influenza vaccine. With the current pandemic context, questions about the COVID-19 vaccine were also added to the survey this year.

Secondary research objectives include:

1.2 Application of Results

The results of this study will help the Public Health Agency of Canada (PHAC) identify at-risk populations with lower immunization coverage, identify factors leading to vaccine uptake or refusal, measure the performance of vaccination programs, and design future vaccination programs in Canada. The survey results also allow PHAC to monitor and evaluate vaccination programs during the flu seasons.

1.3 Methodology—Quantitative Research

The quantitative research consisted of telephone interviews, which were conducted using a computer-assisted telephone interviewing system (CATI technology).

Data collection for this survey took place between January 4 and February 11, 2022. The national response rate for the survey was 15.43%. The comprehensive distribution of calls is presented in Appendix A. A pre-test of 43 interviews, in both official languages, was conducted on January 4, 2022. More specifically, 23 interviews were conducted in French and 20 in English. No changes were made to the questionnaire or the programming following the pre-test, data collection began as planned. The pre-test responses were included in the overall results. The interviews lasted an average of eighteen minutes. The interviews were recorded to assess the level of understanding of each question among respondents.

To obtain reliable data for each of the subgroups, we surveyed a total sample of 3,502 Canadian adults in all regions of the country. Only one adult respondent was interviewed per household. The national margin of error for this survey is +/- 1.66%, 19 times out of 20.

The main target population in this study was Canadian adults aged 18 and older who were making vaccine-related decisions for themselves. As was the case in previous years, the final analysis of the study focused on 3 different target groups:

A proportion of the interviews were conducted with a sample of cell-phone numbers (cell-phone-only household members), in order to provide an adequate and reliable sample of the youth cohort (18 to 34). While the cell-phone sample did not exclusively target the youth cohort, this age group was over-indexed in that target sample. The other interviews were conducted with landline users. According to 2016 national census data from Statistics Canada, Leger weighted the results of this survey by age, gender, region, language (mother tongue) and education level. Results were also weighted by households with a landline phone and household with cellphones only, according to the latest Canadian Radio-Television and Telecommunications commission (CRTC) data available.

Leger meets the strictest quantitative research guidelines. The questionnaire was prepared in accordance with the Standards for the Conduct of Government of Canada Public Opinion Research—Series B—Fieldwork and Data Tabulation for Telephone Surveys. Details on the methodology, Leger's quality control mechanisms, the questionnaire, and the weighting procedures are provided in the appendix.

1.4 Notes on the Interpretation of the Findings

The opinions and observations expressed in this document do not reflect those of the Public Health Agency of Canada. This report was compiled by Leger based on research conducted specifically for this project. This research is probabilistic; the results can be applied to the general population of Canada. The research was designed with this objective in mind.

Appendix A—Detailed Research Methodology

A.1 Quantitative Methodology

A.1.1 Methods

For tracking and comparability purposes, the methodology used for this survey was the same as that of previous waves of surveys. Leger used the same methods as those used in the 2020–2021 survey with respect to sampling methodology, data collection methods and some elements of the questionnaire.

The quantitative research consisted of telephone interviews, which were conducted using a computer-assisted telephone interviewing system (CATI technology). This approach is the most suitable for assessing seasonal influenza vaccination coverage among different subgroups of the Canadian population, while ensuring a high level of representativeness.

Leger meets the strictest quantitative research guidelines. The survey questionnaire was prepared in accordance with the Standards for the Conduct of Government of Canada Public Opinion Research—Series B—Fieldwork and Data Tabulation for Telephone Surveys.

Respondents were assured of the voluntary and confidential nature of the approach, and the anonymity of their responses. As with all research conducted by Leger, any information that could identify respondents was removed from the data, in accordance with Canada's Privacy Act.

Research interviews were conducted from the Montréal and Winnipeg virtual call centres. Montreal call centre has three separate divisions of interviewers: one made up exclusively of English-speaking interviewers, another exclusively of French-speaking interviewers, and the last of bilingual interviewers. These divisions ensure that all telephone surveys can easily be conducted in either official language. Interviews in English were also conducted from the Winnipeg call centre.

A.1.2 Data Collection

Data collection for this survey was conducted between January 4 and February 11, 2022. The national response rate for the survey was 15.43%. The comprehensive distribution of calls is presented below. A pre-test of 43 interviews, in both official languages, was conducted on January 4, 2022. More specifically, 23 interviews were conducted in French and 20 in English. The interviews lasted an average of eighteen minutes.

To obtain reliable data for each of the subgroups, we surveyed a total sample of 3,502 Canadian adults in all regions of the country. Only one adult respondent was interviewed per household. The national margin of error for this survey is +/- 1.66%, 19 times out of 20.

Representative sample of approximately 3,500 Canadians

A sample of Canadian adults was selected using a stratified regional sampling approach. Flexible regional quotas were applied to ensure that a sufficient number of interviews were conducted in each region of Canada.

The following table details the regional quotas for the 3,500 Canadian adults and the effective distribution of the 3,502 respondents:

Table 1. Flexible regional quotas
Region Quotas Number of completed interviews
Atlantic 210 – 250 242
Quebec 770 – 830 792
Ontario 1,300 – 1,400 1343
Manitoba and Saskatchewan 220 – 260 225
Alberta 400 – 440 415
British Columbia 440 – 480 440
Nunavut 15 15
Northwest Territories 15 15
Yukon Territories 15 15
Total 3,500 3,502

A.1.3 Sampling Procedures

Landline telephone numbers were generated, and only cell phone numbers were purchased using a stratified regional sampling approach. Telephone interviews were conducted using Leger's computer-assisted telephone interviewing system (CATI technology). This system manages the sampling electronically, by selecting and randomly dialing the phone number to call. To ensure perfect coverage of a population, the sample included residential telephone numbers located in all of Canada's provinces and territories, as well as the cell phone numbers of Canadians who do not have a residential landline (i.e., pre-validated cell numbers only). Flexible quotas were established to ensure a sufficient number of interviews in each region of Canada. In addition to these regional quotas, data was collected to ensure proper distribution of respondents by gender (men and women) and language (English and French), using flexible quotas.

Canada-wide sampling: Households with a landline

We defined a Canada-wide sample of telephone numbers. All numbers were randomly selected to generate this basic sample. Each telephone number in this sampling frame was associated with a Canadian province. Subsequently, we used this Canada-wide sample to randomly select numbers by province or region, in proportion with the provincial or regional quotas established for the project.

Canada-wide sampling: households with a cell phone number only

For the portion of the sample composed of "cell phone only households," candidates were randomly selected for each province or region taking into account provincial or regional quotas. We set a minimum quota of 1,575 respondents from cell-phone only households to match as closely as possible the proportion of Canadian cell-phone only households estimated by the CRTC (48%). In the end, we collected data among 1,693 respondents from cell-phone only households, representing 48% of our final sample. Statistical weighting corrected the demographic differences between the sample and the actual proportion in the population.

A.1.4 Maximizing Response Rate

A low response rate compromises the reliability and validity of a survey. Based on their experience in surveying various populations, Leger has established the following methods to maximize response rates:

A.1.5 Call Distribution

The overall response rate for this study was 15.43%. The participation rate is calculated using the following formula: Participation rate / response rate = R ÷ (U + IS + R). The table below provides details of the calculation.

Table 2. Call determination and response rate

A.1.6 Non-response Biases and Additional Socio-Demographic Analysis

An effective response rate of 15.43% is around the average for a national telephone survey of 3,502 respondents conducted over a period of approximately five weeks. This rate is consistent with similar surveys. A response rate of more than 10% is considered typical and within industry standards for a telephone survey with the general population.

Weighting

According to Statistics Canada's 2016 national census data, Leger weighted the results of this survey by age, gender, region, language (mother tongue) and education level. In addition, the weighting of respondents in the cell phone-only sample was also controlled to match the 48% of Canadian households with landlines and to correct the difference between the sample and the actual proportion in the population, as per our estimate of CRTC's data.

A baseline comparison of weighted and unweighted samples was also conducted to identify potential non-response biases that could be introduced by lower response rates in some demographic subgroups (see tables in the next section). As is usually the case for a telephone survey targeting mainly households with a landline, it was more difficult to reach young respondents. To compensate for this, Leger conducted 1,693 interviews with individuals whose homes do not have landlines (called on their cell phones) in order to maximize the number of youth in the final sample.

A.1.7 Weighted and Unweighted Samples

The table below shows the geographical distribution of respondents, before and after weighting. There is very little geographical distribution imbalance in the unweighted sample. The weighting process mainly adjusted the weightings of Quebec and British Columbia, which were slightly underrepresented in the sample, and of Alberta, Nunavut, Northwest Territories and Yukon, which were slightly overrepresented in the sample.

Table 3. Unweighted and weighted sample distribution by province
Province or territory Unweighted Weighted
Newfoundland and Labrador 54 53
Prince Edward Island 21 14
Nova Scotia 96 95
New Brunswick 71 76
Quebec 792 818
Ontario 1343 1341
Manitoba 130 123
Saskatchewan 95 105
Alberta 415 392
British Columbia 440 474
Nunavut 15 3
Northwest Territories 15 4
Yukon 15 4

The tables below illustrate the demographic distribution of respondents by gender, age, language (mother tongue), education and household income.

First, with respect to gender, we can see that the weighting adjusted the proportion of female respondents to male respondents, with women still over-represented in telephone surveys.

Table 4. Unweighted and gender-weighted sample distribution
GENDER Unweighted Weighted
Male 1552 1668
Female 1924 1800
Other 18 21
Don't know 3 6
Refusal 5 7

With respect to age distribution, the final weighting of the results corrected some imbalances regarding age groups. Respondents under 55 years old were underrepresented in the final sample, and respondents aged 55 years and older were overrepresented. The weighting corrected that discrepancy.

Table 5. Unweighted and age-weighted sample distribution
AGE Unweighted Weighted
From 18 to 24 years old 194 378
From 25 to 34 years old 477 575
From 35 to 44 years old 476 567
From 45 to 54 years old 518 629
From 55 to 64 years old 733 613
From 65 to 74 years old 672 439
75 years and older 432 302

Some imbalances in language distribution were corrected through weighting, as shown below. The French-speaking respondents were slightly overrepresented and, as such, the respective weights of these respondents were therefore reduced.

Table 6. Unweighted and weighted sample distribution by mother tongue
LANGUAGE (MOTHER TONGUE) Unweighted Weighted
French 838 729
English 2149 2187
Other 508 579
Don't know 2 2
Refusal 5 5

The weighting applied corrected the original imbalance for data analysis purposes; no further manipulation was required.

As with all research conducted by Leger, contact information was kept completely confidential, and any information that could identify respondents was removed from the data, in accordance with Canada's Privacy Act.

A.1.8 Weighting Factors

Certain subgroups tend to be underrepresented or overrepresented in a sample compared to the general population. The weighting of a sample makes it possible to correct for differences in the representation of the various subgroups of that sample compared to what is usually observed in the overall study population. Weighting factors are therefore the weight given to each respondent that corresponds to a subgroup of the sample.

The following tables illustrate the proportion allocated to each target in the sample.
