Highlights from the 2019 childhood National Immunization Coverage Survey (cNICS)

The childhood National Immunization Coverage Survey (cNICS)

cNICS is a survey conducted every two years by Statistics Canada on behalf of the Public Health Agency of Canada since 2011. The survey is given to parents and guardians and measures the proportion of children who have received all routine vaccinations by ages two, seven, fourteen, or seventeen years.

Results from this survey help understand how well Canadian children are protected against vaccine preventable diseases, as well as what parents and guardians know and think about vaccines.

Survey results are used to:

Key Results

The 2019 survey showed that:

The results show that in 2019, like in previous years, a majority of 2-year-old children had received all vaccines recommended for them by their 2nd birthday. Despite this, more work needs to be done to ensure Canada meets its coverage goal of 95% for all recommended childhood vaccines Figure 1).

Data for cNICS are collected primarily from vaccination cards or booklets held by parents and guardians, in which some vaccine doses received by children may be missing or recorded with incomplete or illegible information. Therefore, the actual vaccine coverage is likely somewhat higher than cNICS estimates.

Attitudes and beliefs about vaccines among parents and guardians

To better understand the factors influencing decisions on vaccination, parents and guardians were asked about their views on vaccines (Table 1).
