Vaccines are crucial for preventing the spread of the coronavirus pandemic and controlling its effects. We aimed to determine the desire of children aged 12–18 to be vaccinated with the current vaccines, the reasons for wanting or not wanting to be vaccinated, where they had learned about the vaccine, how many of the children with a history of chronic disease want to be vaccinated, and which factors affect them.

A questionnaire form was completed for children aged 12–18 years who applied to Gazi University Pediatric Emergency Department and the Child Health and Diseases Polyclinic between April 1, 2022, and September 30, 2022.

A total of 924 children participated in the study. The mean age of the participants was 14.64±1.77 years. The willingness to be vaccinated was 83.1%. Being older, living in the city, having a mother, father, or sibling who was vaccinated, information about vaccines obtained from health personnel, a completed national vaccination program, and the presence of a first-degree relative in the healthcare field significantly increased the probability of the child being vaccinated. The most important factors affecting the desire to be vaccinated in children were the vaccination status of the mother, father, or sibling and the completed national vaccination program.

We found that the immunization status of the parents is the most important factor guiding the child's desire to be vaccinated and that the most common reason for vaccine hesitancy is the side effects of the vaccine.
