1. Executive Summary

1.1 Background

Since 1991, the Public Health Agency of Canada has been monitoring national vaccination coverage for selected adult vaccines. The adult National Immunization Coverage Survey (aNICS) was first conducted in 2001 and has been routinely administered every two years since 2006 until 2016 when it was discontinued. The aNICS was conducted in 2001, 2006, 2008, 2010, 2012, 2014, and 2016. Results from aNICS are used to monitor coverage at the national level for vaccines recommended by the National Advisory Committee on Immunization (NACI), to report vaccination coverage estimates against national coverage goals and to inform vaccination programs and public education strategies. Coverage among the general population aged 18 and older for immunization against seasonal influenza, pneumococcal, hepatitis B, tetanus, pertussis, varicella, herpes zoster (shingles), and human papillomavirus (HPV) was reported for each cycle.

As the most recent cycle of data collection for the aNICS occurred in 2016, there is a need for more recent data on immunization coverage among Canadians. National health surveys such as the Survey on Vaccination during Pregnancy (SVP), the COVID-19 Vaccination Coverage Survey (CVCS), and the Seasonal Influenza (Flu) Vaccination Coverage Survey, all conducted by the Public Health Agency of Canada, provide some prevalence indicators for immunization coverage among adult Canadians. However, these surveillance tools do not provide sufficiently comprehensive data on immunization coverage for all vaccine-preventable diseases of interest at national and/or provincial/territorial levels that are required for ongoing monitoring, nor do they provide sufficient data on vaccine hesitancy and knowledge, attitudes and beliefs (KAB) regarding vaccines. In addition, they do not have the capacity to track immunization coverage and KAB relating to emerging vaccine-preventable diseases that may not have been relevant to tracking in the past, such as polio or monkeypox. And finally, there is a need for a better understanding of the current status of immunization coverage among health care workers (HCWs) that is not supported by these surveys, as well as an understanding of the coverage of immunizations recommended prior to travel. These issues lead to data gaps that have an impact on policy and program development.

1.2 Objectives

The primary objective of this research is to obtain both nationally and provincially/territorially (P/T) representative results for immunization coverage among Canadians aged 18 years and older. Specifically, this research aims to provide data on:

Secondary objectives of this research are to understand:

1.3 Methodology

Data collection started April 4, 2023, and ended July 26, 2023, and was conducted by Advanis.

A sample of 368,059 Canadians aged 18 or older were called by random digit dialing (RDD) and invited to participate in an online survey. A total of 47,668 recruits agreed to participate and received an email or SMS inviting them to take part in the survey or agreed to participate directly on the phone.

Of those invited, 12,333 answered the survey. However, 155 were under 18 years old, 9 lived outside Canada and five were removed from the dataset for giving unintelligible responses. Hence, 12,164 were considered to have completed the survey.

Survey results were weighted by region, gender+ and age group. Recruitment ensured quotas were reached for key sub-populations to ensure statistical relevance and representativeness.

1.4 Contract Value

The contract value for this study was $296,396.28 (including HST).

2. Methodology

The Public Health Agency of Canada (PHAC) sought more recent data on immunization coverage among Canadians for all vaccine-preventable diseases of interest at national and/or provincial/territorial levels, an understanding of the current status of immunization coverage among health care workers, adults with chronic medical conditions and seniors, as well as an understanding of the coverage of immunizations recommended prior to travel. PHAC contracted Advanis to conduct the Adult National Immunization Coverage Survey (aNICS) 2023. It was initially planned to be a 15-minute online survey and 17-minute phone survey of Canadians 18 years and older.

To reach respondents, Advanis used a two-staged approach where respondents were first recruited by telephone (RDD with both landline and mobile) using a short battery of screener questions approved by Health Canada. During the second stage, the potential respondents were sent a link by SMS or email to an online survey where the core survey data was collected.

Advanis recruited respondents from a list of random telephone numbers that Advanis had verified are in service. This list consisted of approximately 90% mobile numbers and 10% landlines.

During the RDD recruit, respondents were allowed to complete the entire survey directly on the phone if explicitly requested. This was done to improve the response rate for harder to reach populations.

Respondents were recruited to the online survey by either email or SMS (text message), based on their preference stated at the time of the phone recruitment. After the initial invitation, if respondents had not yet completed the survey, they were sent a reminder message. Reminder messages were sent 3, 6 and 9 days after the initial recruitment.

2.1 Survey Questionnaire

The questions for this survey were designed by the Public Health Agency of Canada and supplied to Advanis. The questionnaire was translated into French by Advanis. It contained questions about knowledge and beliefs towards vaccination, vaccine history and vaccination status, travel plans as well as background and demographic information.

The Government of Canada’s standards for pre-testing were adhered to, and pretests were conducted in both English and French. The pretest was conducted on April 4, 2023. This led to 27 completed online surveys (15 French, and 12 English). After the pretest it was decided to change the “White European” level at question G3 asking for the racial or ethnic community of the respondent, to “White (e.g., European, Caucasian, etc.)” to avoid any confusion among respondents. At E3a, the “COVID-19 vaccine” level was added, and the expected survey length was adjusted in the introduction. No further changes were made to the survey and the pretest data was retained in the final dataset.

2.2 Sampling and Administration

The target audience for this project included:

Overall, 368,059 phone numbers were called and 47,668 people were recruited to participate in the survey. A total of 12,179 responded on the web and 154 preferred to answer directly on the phone for a sum of 12,333 respondents overall. To be noted, 155 were under 18 years old, 9 lived outside Canada and five were removed from the dataset for giving incoherent responses.

Hence, 12,164 (9,721 in English and 2,443 in French) were considered to have completed the survey. The overall response rate for people recruited to participate in the web survey was 25.9% Footnote 3. The margin of error was +/-0.89% (19 times out of 20 at a 95% confidence interval). The average length of the survey was 14 minutes for the web survey and 25 minutes for the phone survey.

2.3 Weighting and Data Cleaning

Overall, 12,164 surveys were completed. A direct weighting approach was used based on 3 variables: region, gender+, and age. The weights are based on the most recent Statistics Canada census information that is publicly available, the 2021 census.

The non-binary, two-spirit/bi-spirit, and other genders population is small, and data aggregation to a two-category gender variable (denoted by the "+" symbol) is often used to protect the confidentiality of responses provided. Non-binary persons, and two-spirit/bi-spirit persons, and persons of other genders were randomly classified as men+ and as women+ (total n = 40) to reflect the categories of the Statistics Canada Census of 2021. This results in two gender categories: "men+" and "women+". The men+ category includes cisgender men, transgender men and 50 % of non-binary person, two-spirit persons, bi-spirit persons and persons of other genders. The women+ category includes cisgender women, transgender women and 50 % of non-binary persons, two-spirit persons, bi-spirit persons and persons of other genders.

Bootstrap weights were generated by drawing random samples with replacement from the primary sampling units; each bootstrap sample generated the same number of responses as the original data set. These weights were calculated using the same method implemented in the direct approach described above. There was no need to reduce the risk to contravening confidentiality, since all the different groups described in the weighting scheme participated in the study. The final number of weights created equals the number of bootstrap samples generated. A total of 500 mean bootstrap weight variables are provided in a separate file.

A review of open-ended responses was also performed as part of the data cleaning. Any “other” responses were recoded into existing categories when appropriate and new categories were created. All original verbatims were kept in the database.

2.4 Quality Control

Advanis employs several quality control measures to ensure success across the entire life cycle of the project. These measures are detailed below.p

Survey Programming: Advanis utilizes technology to maximize quality control in survey programming. Having developed a proprietary survey engine tool, Advanis professionals are able to design and program a survey in a browser-based environment, eliminating the need to involve a programmer who is less familiar with the survey subject matter. The survey was thoroughly pre-tested by Advanis’ project team members, as well as by non-team members (non-team members provide “fresh eyes” for catching potential errors).

CATI Methodology: The CATI recruit script was programmed on Advanis’ proprietary CATI platform with no unforeseen challenges. Advanis was able to leverage its experience for the survey programming and the reminder process to achieve high quality standards. Advanis implemented the following to ensure the highest quality data collection:

To ensure high interview quality, our interviewers are trained to use various interviewing techniques. As well as maintaining a professional attitude, our interviewers must also be convincing, read word-for-word, take notes, systematically confirm the information given and listen to the respondent. Advanis has also created internal tools within the survey script for interviewers allowing them to use the phonetic alphabet to confirm email address spelling (e.g., a for alpha, b for bravo, etc.) to help reduce the amount of bounced email addresses. However, should bounced emails occur, Advanis also has developed additional tools that allow for someone to re-listen to the recording and easily adjust to correct the email address.

Web Methodology: All Advanis web surveys are hosted internally by Advanis, and employ a rigorous and stringent set of data collection control mechanisms to ensure the highest quality for the data collected, including:

Data Handling and Reporting: For the data collected, Advanis develops rules to check the validity of the data. These rules include items such as:

All data cleaning performed on projects are outlined and tracked in an internal spec document so they can be QA’d and signed off on. The original raw data file is never overwritten, so that if an error is discovered in our code, we can quickly and easily rerun things to produce a new data file. Individuals developing code incorporate internal checks in their code (e.g., crosstabs) to ensure the adjustment had the desired effect. In addition, all recordings are reviewed by another team member or technical specialist for accuracy.

3. Non-response Bias and Limitations

Non-response bias occurs when non-responders differ in a meaningful way from respondents and this difference impacts the information gathered. It is difficult to assess the presence of non-response bias since information about why non-responders did not participate is usually unavailable. That said, one way to gauge the potential impacts of non-response bias is to evaluate if the sample is representative by comparing the respondents' characteristics and gauge if they reflect known population characteristics. Where possible, we can check the distribution of respondents across various demographics (e.g., age and gender) and geographic categories and compare those distributions against known population characteristics. If the variation is fairly small and we have no reason to believe there are other factors impacting respondents’ willingness to participate, we can conclude that the likelihood of non-response bias impacting the information gathered in the study is minimal. This is the case with the current study.

Several strategies were employed to increase response rates and reduce the effects of non-response bias. This includes:

4. Guidelines for Analysis and Release

When doing an analysis, it is important to align the analysis plan with the weighting scheme. The weights adjust the data to better reflect the population based on parameters that have been chosen to maximize the level of detail without creating distortions due to extreme weights (an extreme weight will occur when a population group is represented by a proportionally smaller subset of respondents compared to other population groups, thus introducing an important risk of bias due to their specific profile).

For this survey, the basic sociodemographic information that should be used in the analysis of results are:

Using age groupings other than the ones described above could potentially produce distorted data. As these results would be inaccurate based on how the weights were calculated, we strongly advise not to report any results that are not aligned with these specified categories.

Any results with an unweighted denominator size of less than 30 should not be reported, due to statistical robustness.Footnote 4,Footnote 5 This is due to the increased coefficient of variation and, hence, there are larger confidence intervals around results with smaller bases. Furthermore, for confidentiality purposes, any results with a numerator size of less than less than 5 (i.e., 1 to 4) should be suppressed.

For all estimates based on a denominator size of 30 or more, the following guidelines for data suppression related to coefficient of variations (CV) should be used when reporting estimates:Footnote 6

Guidelines for data suppression related to coefficient of variations (CV)
Type of Estimate CV (in %)Footnote 6 Guidelines
Acceptable CV ≤ 15.0 Estimates can be considered for general unrestricted release. Requires no special notation.
Marginal 15.0 < CV ≤ 35.0 Estimates can be considered for general unrestricted release but should be accompanied by a warning cautioning users of the high sampling variability associated with the estimate.
Unacceptable CV > 35.0 It is recommended to not release estimates of unacceptable quality.

Examining the confidence interval of the estimate will provide further indication of the quality of the estimate in terms of the variability. Long confidence intervals indicate less precision in the estimate while smaller confidence intervals indicate greater precision. When assessing the trustworthiness of sample proportions, the confidence intervals of estimates should be taken into account.Footnote 6

4.1 Rounding Guidelines

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