Key highlights

Introduction

The Childhood Seasonal Immunization Coverage Survey (CSICS), (previously known as the Childhood COVID-19 Immunization Coverage Survey) is an annual survey conducted by the Public Health Agency of Canada to measure the proportion of children in Canada who have received a COVID-19 vaccine and/or a seasonal influenza vaccine during the 2023-2024 influenza season (September to March). The survey is given to parents or guardians who have children younger than 18 years of age. In Canada, both the COVID-19 and seasonal influenza vaccines are recommended for children and youth 6 months and older, and especially for populations at risk, such as immunocompromised individuals.

CSICS provides key information about COVID-19 and seasonal influenza (flu) vaccination coverage among children and parents/guardians, parental knowledge, attitudes and beliefs (KABs) regarding these vaccines, intention to vaccinate, hesitancy and barriers to vaccination, COVID-19 diagnosis and recommendations from healthcare providers, along with select demographic information. In addition, the 2024 CSICS also asks about receiving the COVID-19 and seasonal influenza vaccines at the same time.

COVID-19 and seasonal influenza vaccination coverage estimates were collected for children 6 months to 17 years of age.

Detailed results tables and the methodological report are published on the Library and Archives Canada website. The following summary presents survey findings from the third cycle of data collection, which started on April 18th, 2024, and ended on July 15th, 2024. All differences noted are significant at the 95% confidence interval.

Parental reasons for COVID-19 vaccination or obstacles that prevented vaccination

COVID-19 vaccine hesitancyFootnote 3

Parents/guardians of children younger than 18 years of age were asked if they were hesitant to get a COVID-19 vaccine for their child, regardless of whether the child got a COVID-19 vaccine or not. Overall, 43% of parents/guardians of children below 18 years of age indicated they were hesitant to vaccinate their child against COVID-19, similar to 2023 (44%), regardless of child's vaccination status.

The most common reasons for COVID-19 vaccine hesitancy were concerns that not enough research on the vaccine has been done in children (64%), followed by concerns about the safety of COVID-19 vaccines and/or side effects (39%) and concerns about the effectiveness (32%). These were also the top three reasons for hesitancy in 2023.

COVID-19 vaccine refusalFootnote 4Footnote 5

In this cycle, parents/guardians were asked whether they intentionally decided to not vaccinate their children aged 6 months to 17 years against COVID-19, if their child had not received a vaccine or did not disclose vaccination status. Results are not comparable to 2023 due to a change in the wording of the question (changed from "Why did you refuse a COVID-19 vaccine for your child" to "Did you intentionally decide not to get a COVID-19 vaccine for your child"). 79% of parents/guardians indicated they refused to vaccinate their child against COVID-19, with the following:

Knowledge, attitudes and beliefs

To better understand factors influencing decisions on COVID-19 and influenza vaccinations, additional questions were asked of parents/guardians. These questions were designed to determine their knowledge, attitudes and beliefs around vaccines (Table 2) and to understand if there is any relation to their child's vaccination status. Parents were asked their level of agreement with a series of statements about childhood vaccines.

Summary

COVID-19 vaccination coverage

To summarize, 67% of children 6 months to 17 years of age have been vaccinated with at least one dose of a COVID-19 vaccine. The results revealed significant age differences in COVID-19 vaccination coverage; among those that received at least one dose of a COVID-19 vaccine, children 6 months to 4 years have the lowest coverage (34%) compared to 5- to 11-year-olds (68%) and 12- to 17-year-olds (89%).

Overall, 25% of children 6 months to 17 years were recommended by a health care provider to receive a COVID-19 vaccine. Vaccination coverage was higher in those that were recommended to get a COVID-19 vaccine (84%) compared to those who did not consult a health care provider (69%) or those who indicated a health care provider recommended against a vaccine (37%).

The most common reason for parents/guardians to get their child vaccinated was to protect themselves and/or household members against COVID-19 infection (65%). Overall, 17% reported they definitely will keep their child's COVID-19 doses up to date, and in the future 23% indicated they probably will. The most common reason for not vaccinating child against COVID-19 was perceptions of low vaccine safety/concerns about side effects (48%).

Parental hesitancy to vaccinate their child or to vaccinate themselves was similar to 2023 (43% and 41%, respectively). The main reason for hesitancy reported by parents/guardians was concern that not enough research on the vaccine has been done in children (64%). Overall, 79% of parents/guardians refused to vaccinate their children. Among parents/guardians that had not received a COVID-19 vaccine (9%), 96% refused to get the vaccine for themselves.

Similar trends to last cycle, parents/guardians who reported their children got all recommended routine childhood vaccinations were more likely to report their child received at least one dose of a COVID-19 vaccine (70%), compared to those who received some routine vaccinations (38%) and who did not receive any routine vaccinations (11%).

Seasonal influenza vaccination coverage

Overall, 31% of children 6 months to 17 years have received their influenza vaccine during the 2023-2024 influenza season. The most common reason to get their child the influenza vaccine was to protect themselves and/or household members from influenza (71%).

Parents were also asked about intentions to vaccinate their child in the next influenza season; 49% of parents intend to vaccinate their child against influenza in the 2024-2025 influenza season.

There were no major differences between parental/guardian hesitancy to vaccinate their child against influenza (29%) than they were to vaccinate themselves (27%). 58% of parents/guardians refused to get their child the influenza vaccine, while 67% of parents/guardians refused to get the influenza vaccine for themselves. The most commonly reported reason for influenza vaccine hesitancy was that parents were concerned about the effectiveness of the influenza vaccine (40%); while the most common reason for refusing to vaccinate was that they did not consider it necessary for their child (56%).

Socio-demographic characteristics

Among reported ethnicities, COVID-19 and influenza vaccination coverage were highest among children identifying as East/Southeast Asian (74%, 43%, respectively), Latin American (71%, 33%, respectively), and South Asian (66%, 38%, respectively) descent. COVID-19 vaccine and influenza vaccination coverage were lower among children identifying as Middle Eastern and North African (63%, 26%, respectively) and Black (56%, 27%, respectively). Children living in urban areas had higher COVID-19 and influenza vaccination coverage estimates (69% and 33%, respectively) compared to children living in rural areas (57% and 23%, respectively). More children with a pre-existing medical condition or a disability received the COVID-19 and influenza vaccines compared to those who do not have a medical condition or disability.

Knowledge, attitudes and beliefs

The majority of parents agree that vaccines in general, COVID-19 and influenza vaccines are safe and effective. Most parents/guardians agreed they have access to enough trustworthy information to make an informed decision about COVID-19 vaccines (83%). However, 44% of parents disagree that their child needs to be vaccinated against COVID-19 even after infection.

The most trusted source of information reported was health care providers (42%), followed by scientific publications or journals (17%) and Public Health Agency of Canada/Health Canada (13%).

Considerations and limitations

Due to the collection methodology and the nature of the survey, CSICS estimates of COVID-19 vaccination coverage in children below 18 years of age may be higher than results reported by the Canadian COVID-19 Vaccination Coverage Surveillance System (CCVCSS). Children living in the North were oversampled to gain more information on Indigenous people, although specific efforts to oversample children residing on-reserve and across the Inuit Nunangat regions were not carried out. Institutionalised children and youth are also not included. Furthermore, caution must be taken when making comparisons between the 2022, 2023 and 2024 cycles of CCICS/CSICS in terms of COVID-19 vaccination coverage; in the 2022 cycle of CCICS, children below 5 years were not included in coverage estimates as they were not eligible at the time of data collection, while in the 2023 and 2024 cycles they were included.

Footnote 1

Please note, that during the 2022 survey cycle, children younger than 5 years were not eligible for COVID-19 vaccination, whereas in 2023 and 2024 they were. Therefore, coverage comparisons between 2022 and 2023 were among children 5 to 17 years of age, while comparison between the 2023 and 2024 are among children 6 months to 17 years of age.
