Childhood National Immunization Coverage Survey (CNICS)

Search box

This study is conducted in collaboration with the Public Health Agency of Canada. The purpose of the Childhood National Immunization Coverage Survey is to collect information on national immunization coverage for vaccines administered to children and pregnant women.

Your information may also be used by Statistics Canada for other statistical and research purposes.

The survey is intended to:

  • determine if children and pregnant women are vaccinated in accordance with recommended immunization schedules for publicly funded vaccines;
  • provide the World Health Organization and the Pan-American Health Organization with estimates of national vaccine coverage for childhood vaccines such as measles, diphtheria, pertussis, tetanus and polio;
  • provide information on parental and guardian knowledge and beliefs about vaccines.
Collection period:
From December 2, 2019, to April 30, 2020
Collection methods:

Electronic questionnaire, telephone interview and mail-out/mail back

For children aged 2, 7, 14 and 17 years-old, the survey should be completed by the person most knowledgeable of the child's immunization history, or in the case of women with children under age 1, by the birth mother herself.

Parents or guardians will be asked to complete an electronic questionnaire or a telephone interview about vaccines their child has received, in addition to questions about their knowledge and beliefs regarding immunization.

Following the completion of the questionnaire, they will be asked to complete and return by mail a form which provides consent for Statistics Canada to contact their child's immunization providers. The data from immunization providers will be used to supplement the vaccination information provided by the parent or guardian. Respondents living in Prince Edward Island and Manitoba will also be given the opportunity to skip the detailed questions about vaccination, providing they agree to share their child's identifiers with the respective provincial immunization registry. When consent is provided, registry immunization data will be used in the place of parent or immunization provider data.

In 2019, the survey includes a module for women who have recently given birth. Biological mothers will be asked questions about vaccines they were offered and received during their recent pregnancy, in addition to questions about their knowledge and beliefs regarding immunization. The survey will be conducted via an electronic questionnaire or a telephone interview, and Statistics Canada will not contact immunization providers for these respondents.

    Immunization and the health of our children - The Childhood National Immunization Coverage Survey

    Children and youth: A health priority

    Recent events, such as measles outbreaks, have highlighted the need for up-to-date data on childhood immunization coverage.

    Developing policies and programs to ensure children are protected against disease requires a complete picture of the factors that influence parental decisions about immunization.

    You can make a difference

    The information collected by the Childhood National Immunization Coverage Survey (CNICS) will allow us to measure the immunization status of children across Canada, and will provide insight into parental knowledge of vaccines and the diseases they prevent.

    Your participation in this survey will help policy-makers to determine where improvements are needed for prenatal, childhood, and youth immunization programs and services.
