Vaccination is one of the most common invasive procedures performed on healthy infants and children. These procedures can cause pain and fear in children and anxiety in parents. This study will be conducted to determine the effect of using animal-shaped magic mirrors during vaccination on pain in children aged 1-4 years and anxiety in mothers.

The study is a randomized controlled experimental trial. Research data will be collected between February 1 and August 30, 2026. The study population will consist of children aged 1-4 years and their mothers who visit the Pediatrics Outpatient Clinic at Ankara Özel Koru Hospital. The sample will include 126 children and their mothers (Intervention group n=63; Control group n=63) who apply to the Ankara Koru Hospital Pediatric Outpatient Clinic for vaccination and meet the inclusion criteria. Children in the intervention group will be shown a magic mirror with animal figures at the moment of needle insertion during vaccination, while children in the control group will receive routine care without any intervention by the researchers. Data will be collected using the Informed Consent Form, the Eastern Ontario Children's Hospital Pain Scale, and the State Anxiety Inventory.

Descriptive statistics, Student's t-test or Mann Whitney U test for independent two-group comparisons, and t-test or Wilcoxon signed-rank test for dependent groups will be used in the analysis of the study. Statistical significance will be set at p<0.05.

Expected Results: The findings from this study are expected to contribute to the development of new non-pharmacological methods to reduce pain experienced by children during vaccination and to reduce negative emotions such as anxiety associated with the procedure in parents.

Inclusion Criteria:

• Mothers who have completed at least primary school and have no hearing, visual or intellectual disabilities.

Exclusion Criteria:

• Children or their mothers who do not wish to participate during the vaccination process,
• Children or their mothers who wish to withdraw from the study during the research process,
• Those who provide incomplete answers to the study questions will be excluded from the study.
