1. Executive Summary

Leger is pleased to submit this report to Health Canada detailing the methodology of an online survey assessing immunization coverage and attitudes and beliefs of healthcare worker parents towards child vaccination.

1.1 Background

Surveillance data suggests that vaccine coverage is uneven across Canada. Furthermore, results from existing surveillance tools suggest that certain key at-risk populations are under-surveyed. The childhood National Immunization Coverage survey (cNICS) is a general population survey that measures routine childhood immunization coverage among children aged 2, 7, 14 and 17 years and COVID-19 vaccine uptake in children ages 14 and 17 years, as well as parental knowledge, attitudes and beliefs about vaccination. This surveillance tool provides critical information about childhood immunization in Canada, though is limited in that it was not designed to sample from all child age ranges or from key at-risk populations.

Consequently, this results in insufficient data regarding routine childhood immunization status and COVID-19 vaccine coverage, and knowledge, attitudes and behaviors towards vaccination within these specific groups. In turn, this hinders core immunization functions including COVID-19 vaccine and routine childhood immunization surveillance, vaccine confidence, available data, policy, public health guidance, and knowledge mobilization activities.

In addition, the COVID-19 pandemic yielded a large shift in Canadians' knowledge, attitudes, and beliefs towards vaccinations. For certain populations, such as Indigenous peoples, recent evidence points that there has been a high prevalence of vaccine hesitancy and refusal for COVID-19 vaccines. Monitoring of parental attitudes is essential to predict expected vaccine uptake and to guide education and awareness efforts to promote vaccination among children issued from these specific populations.

Surveillance tools are needed to address data coverage gaps identified for these sub-populations and to inform public health vaccination programs and initiatives. In the effort of addressing vaccine coverage data gaps relating to at-risk populations, the Public Health Agency of Canada (PHAC) sought third party support to implement the cycle 2 of the surveillance initiative, the Childhood Immunization Coverage Survey in Key Populations (KPCICS) in Canada.

Rationale and Intended Use of Research

Results will be used by PHAC to provide timely, trusted, and evidence-based information for Canadians to take action on their children and collective health and safety regarding COVID-19 risk and other vaccine-preventable diseases. The surveillance project findings will also support equity in vaccine coverage by identifying determinants associated with low vaccine uptake or vaccine hesitancy in identified at-risk populations, including health care workers. Additional information collected from this population regarding their knowledge, attitudes, and beliefs, experiences, and barriers to vaccination will inform policy development and guide public education and awareness efforts.

1.2 Research Objectives

The core objective of this survey is to maintain a surveillance tool that provides up-to-date vaccine coverage data (e.g., on measles, diphtheria, tetanus, pertussis, polio, COVID-19) specific to the children of health care workers. The survey will assess parent/guardian/other Person most knowledgeable (PMK)'s (e.g., child's step-parent, adoptive parent, foster parent, sister or brother, grandparent or relative caring for and responsible for health decisions for the child) opinions and views on their child's immunization uptake, as well as vaccine hesitancy and vaccine refusal. This survey will also investigate the reasons for vaccine hesitancy among these populations and the impact this has on childhood immunization.

The second objective is to continue to monitor the effects of the COVID-19 pandemic (and any new possible waves of COVID-19) on concurrent childhood immunizations to determine priorities for vaccine-preventable diseases, with the aim of identifying whether catch-up routine immunization campaigns are required.

The surveillance project aims to collect information on:

1.3 Methodology—Quantitative research

Quantitative research was conducted through online surveys using Computer Aided Web Interviewing (CAWI) technology between March 28 and April 25, 2024, with a total sample of 405 healthcare workers who are parents of children aged 17 and under.

While the LEO panel is meant to be representative of the Canadian population, it is not probabilistic; the results cannot be inferred to the healthcare worker parents population of Canada nor their children, as respondents are selected among those who have volunteered to participate/registered to participate in online surveys The sampling method used does not ensure that the sample represents the target population with a known margin of sampling error.

1.4 Contract value

The total contract value for the project was $38,489.10 including applicable taxes.

2. Methodology

2.1. The sample source: LEO panel

Leger owns and operates an Internet panel of more than 400,000 Canadians from coast to coast. An Internet panel is made up of Web users profiled on different sociodemographic variables. The majority of Leger's panel members (61%) have been recruited randomly over the phone over the past decade through random digit dialing (RDD) methods, making it highly similar to the actual Canadian population on many demographic characteristics.

While the LEO panel is meant to be reflective of the Canadian population, it is not probabilistic; the results cannot be inferred to the general population of Canada as respondents are selected among those who have volunteered to participate/registered to participate in online surveys.

2.2 Survey design

The questions for this survey were designed by the Public Health Agency of Canada and supplied to Leger in both English and French. Leger reviewed the French survey translations. The questionnaire contained core questions about routine childhood and COVID-19 immunizations, including vaccination status, barriers to vaccination, knowledge attitudes and beliefs related to vaccination, demographics, and questions about general health. In this iteration of the KPCICS, flu questions were separated out from routine Childhood vaccines.

The Government of Canada's standards for pre-testing were adhered to. The pretest was conducted in both English and French. The pretest was conducted between March 25 and 28, 2024. This led to 29 completed online surveys (13 French, and 16 English). After the pretest, minor wording changes were made to the questions, and minor corrections were made to the programming. For instance, the back button on the survey, which enables respondents to go back and change their answers, was removed as it created glitches in the questionnaire flow. Furthermore, some changes to skip logics were put in place to improve the survey flow (e.g., respondents who answered "I prefer not to answer" at C3c were excluded from answering C8). Responses that were not affected were included in the final results. A total sample of 405 healthcare workers who are parents of children aged 17 and under were surveyed. The questionnaire is presented in Appendix B.

Among those completing the survey online, the median survey length was 10 minutes while the average survey length was 12 minutes.

2.3 Sampling and administration

The target audience for the survey was health care workers in Canada who are parents/guardians/ PMK (e.g., child's stepparent, adoptive parent, foster parent, sister or brother, grandparent or relative caring for and responsible for health decisions for the child) for a child(ren) aged 17 years or younger living across the country. The minimum targeted number of completed surveys was 405 Canadian HCW parents. Questions within the survey further filtered out responses from anyone under the age of 18 years (S1) and responses for anyone who is not the parent/legal guardian of a child(ren) under the age of 18 (S2) and not being HCW. A total of 405 responses were obtained. The national participation rate for the survey was around 15%. Calculation of the Web survey's participation rate is presented in Appendix A.

A portion of the sample (371 respondents out of 405) comes from the portion of the LEO panel that was recruited using random digit dialing (RDD) methods. Although the sample containing 34 respondents was recruited using non-probabilistic methods, only the RDD-recruited panel sample has been considered in the analyses to enhance data validity and facilitate data interpretation.

A total sample of 405 healthcare workers who are parents of children aged 17 and under were surveyed. The following table shows the effective samples collected:

Table 1. Distribution of participants by region
Regions Total sample n Probability sample n Non-probability sample n
Atlantic (New Brunswick + Nova Scotia + Newfoundland and Labrador + Prince Edward Island) 38 35 3
Quebec 91 85 6
Ontario 120 109 11
Saskatchewan + Manitoba 30 27 3
Alberta 48 42 6
British Columbia + Territories 78 73 5
TOTAL 405 371 34

The margins of sampling error cannot be calculated for surveys using non-probabilistic sampling.

2.4 Weighting and data cleaning

Based on data from Statistics Canada's 2021 national census, Leger weighted the results of this survey by age and sex at birth of selected child, and HCW parent's education level, gender, age and region.

The demographic profile derived from Statistics Canada is applied to the entire administrative database via statistical method for weighting. The administrative database includes all participants who attempted to complete the study, including those who are not eligible, as well as incomplete records. This process helps adjust all data in the administrative database to mirror the demographic structure of the general population.

Once the weights are applied to the administrative database, the demographic profile of eligible individuals (HCW parents) is extracted. This profile is considered reflective of the target population and is then applied to the eligible and completed subset of the sample (i.e., the total of 405 healthcare workers who are parents of children aged 17 and under). This step ensures that the final analysis is more reflective of the target population.

Other data cleaning and data processing methods were used, including:

Further details regarding the weighting procedures can be found in Appendix A.

2.5 Quality control

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— Online Surveys.

The details of Leger's quality control mechanisms are presented in Appendix A.

3. Non-response Bias

A basic comparison of the unweighted and weighted sample sizes was conducted to identify any potential non-response bias that could be introduced by lower response rates among specific demographic subgroups (see A.5 Unweighted and weighted samples for further details). The small differences observed have not introduced a non-response bias for any of the subgroups. Further details regarding quality control and strategies undertaken to increase response rates and curtail the effect of non-response bias are included in Appendix A.

4. Notes on the interpretation of the findings

The respondents were randomly selected from members of our panel (LEO), part of which were recruited using random digit dialing (RDD) methods, ensuring that the sample closely resembles the actual population of Canada. While the LEO panel is meant to reflect the Canadian population, it is not probabilistic; the results cannot be inferred to HCW parents population in Canada as respondents are selected among those who have volunteered to participate/registered to participate in online surveys. The sampling method used does not ensure that the sample represents the target population with a known margin of sampling error.

A portion of the sample (371 respondents out of 405) comes from the portion of the LEO panel that was recruited using random digit dialing (RDD) methods. The remainder of the sample (34 respondents out of 405) was based on non-probabilistic recruitment methods. Even though Random Digit Dialing (RDD) is a probabilistic sampling method, the RDD sample is considered non-probabilistic as it is internet panel based.

5. Guidelines for Analysis and Release

Any results with an unweighted base size (denominator) of less than 30 should be interpreted with caution.1 - 2 Furthermore, for confidentiality purposes, any results with a base of less than 10 should be suppressed.

5.1. Rounding Guidelines

Users are urged to adhere to the following rounding guidelines for estimates.

Appendix A—Detailed research methodology

A.1 Methods

Research was conducted through online surveys using Computer Aided Web Interviewing (CAWI) technology between March 28 and April 25, 2024. A total sample of 405 health care workers who are parents of children aged 17 and under were surveyed. Of these, 371 were randomly selected from the portion of the LEO panel that was recruited using probabilistic methods.

Leger adheres to the most stringent guidelines for quantitative research. The survey was in accordance with Government of Canada requirements for quantitative research, including the Standards of the Conduct of Government of Canada Public Opinion Research – Series A—fieldwork and data tabulation for online surveys.

Respondents were assured of the voluntary, confidential and anonymous nature of this research. As with all research conducted by Leger, all information that could allow for the identification of participants was removed from the data, in accordance with the Privacy Act.

A.2 Sampling Procedures

Computer Aided Web Interviewing (CAWI)

Participant selection was done randomly from Leger's online panel (LEO), part of which were recruited using random digit dialing (RDD) methods. Leger owns and operates an Internet panel of more than 400,000 Canadians from coast to coast. An Internet panel is made up of Web users profiled on different sociodemographic variables. The majority of Leger's panel members (61%) have been recruited randomly over the phone over the past decade, making it highly similar to the actual Canadian population on many demographic characteristics.

As recruitment for the LEO panel is ongoing, each member of the Canadian public with a phone had a chance of being recruited to the Internet panel and thus the survey sample.

While the LEO panel is meant to be reflective of the Canadian population, it is not probabilistic; the results cannot be inferred to the general population of Canada as respondents are selected among those who have volunteered to participate/registered to participate in online surveys.

A.3 Quality control

The research team supervised programming and ensured that each question, response category and skip patterns have been properly entered and this, even after this information has been verified by two separate programmers and a data analyst, to check for consistency. The Project Authority at Health Canada also tested the programmed survey demo link.

In broad terms, Leger's quality methodological approach for an online survey includes the following steps:

Upon completion of data collection for online surveys, Leger's data analysts and data processing department will clean the data thoroughly, ensuring that:

The data is checked and cleaned after the pretest, after the first night of field, and at project completion. During analysis, all numbers are double-checked to ensure the data has been entered accurately in the first place.

Additional Data Quality Checks for Online Completions

To make sure that online respondents answered the survey properly and seriously, Leger proposes two basic methods. The first one is to insert validation questions within the questionnaire, such as: "Please select all the animals from the list below." Respondents who do not choose the animals in the list would then be automatically excluded from the survey. Our experience shows that including such questions reduces the likelihood that respondents do not read the questions. The filter questions used varies from survey to survey so as not become too obvious to all respondents.

In addition to this simple filter, Leger also checks its survey completion times so that all questionnaires filled more than twice as fast as the median completion time are checked for internal consistency. If there are any indications that responses are following a "straight-lining" pattern or contain too many residual answers (don't know or refused), this respondent would be removed from the study.

Finally, in order to increase response rates and curtail the effect of non-response bias, several measures are put in place, including:

A.4 Participation Rate for the Web Survey

The national participation rate for the survey was around 15%. Below is the calculation of the participation rate to the web survey. 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. Participation rate

Completed surveys disqualified for other reasons – ineligible respondents 7,900
Completed interviews 405
POTENTIAL SAMPLE (U+IS+R) 55,291
Participation rate = R ÷ (U + IS + R) 15.02%

The participation rate for the survey was around 15%. A 15% participation rate among the target audience is consistent with similar surveys. On the other hand, because of the particularity of the target audience of healthcare workers who are parents of children aged 17 and under, Leger had to invite a large number of parents to participate; 55,000 invitations were sent. Each potential respondent received 1 reminder to complete the survey. Since the age of children is only identified by age brackets in the profile of the panelists, the question was asked to a large number of parents in order to identify those who qualify for the survey and reach the minimum target survey quota.

A.5 Unweighted and Weighted Samples

The results of this survey were weighted by region, child's age and sex at birth, and HCW's parent's education level, gender, and age, based on data from Statistics Canada's 2021 national census. Because the survey was designed to gather information on both children's vaccination status and parents' attitudes towards vaccines, both parents' and children's demographic profiles were used for weighting.

The demographic profile derived from Statistics Canada is applied to the entire administrative database via statistical method for weighting. The administrative database includes all participants who attempted to complete the study, including those who are not eligible, as well as incomplete records. This process helps adjust all data in the administrative database to mirror the demographic structure of the general population.

Once the weights are applied to the administrative database, the demographic profile of eligible individuals is extracted. This profile is considered reflective of the target population and is then applied to the eligible and completed subset of the sample (i.e., the total of 405 healthcare workers who are parents of children aged 17 and under). This step ensures that the final analysis is more reflective of the target population.

Other data cleaning and data processing methods were used, including:

The tables below present the distribution of the target population by region, child's sex at birth and age, and HCW's parent's education level, age and gender before and after weighting.

Some proportions did not align with the actual population. The weighting process adjusted those differences.

A.6 Weighted distribution

Certain subgroups tend to be underrepresented or overrepresented in a sample compared to the target 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 weighting applied corrected the original imbalance for data analysis purposes; no further manipulation was required.

The results of this survey were weighted by region, child's age and sex at birth, and HCW parent's education level, gender, and age, based on data from Statistics Canada's 2021 national census3. The data sources used for weighting are presented below the tables.

The following tables illustrate the proportion assigned to each target audience in the final sample and in the administrative database. In other words, the table presents the weighted distribution of each profile in the final sample and in the administrative database.
