Objective: to estimate the effect of virtual reality as a distracting technique against traditional distracting techniques in the vaccination procedure in the pediatric population.

Design: randomized clinical trial. Field of study: the study will be carried out in the field of pediatric primary care nursing consultation, where the pediatric systematic vaccination is performed.

Subjects to study: the sample will be made up of children from 3 to 14 years old who are punctured for immunization in the Fuensanta Health Center that belongs to the Department of Health Valencia-General Hospital.

Variables: age, sex, family country of origin, years living in Spain, number of children of the nuclear family, order in the number of siblings, socioeconomic level, age of the caregiver that accompanies the child, affiliation / bond with the child . Group to which the subject belongs (intervention group vs. control group). Number of punctures received in the last year. Heart rate pre and post vaccination. Type of vaccine. Combination of several punctures in the query. Previous use of virtual reality. Level of pain and fear after puncture. Parent or legal guardian satisfaction.

Data collection: it will be held at the Health Center on the same day as the vaccination prodecure. On the part of the nurse (heart rate, type of vaccine, combination of several punctures), the child (pain, fear) and the parents / legal guardian (satisfaction, sociodemographic).

Data analysis: The descriptive analysis of the quantitative variables will be carried out through the calculation of means, typical deviations, medians, ranges, minimum and maximum values. Qualitative variables will be analyzed in absolute and relative frequencies. For the statistical inference analysis, the T-test analysis of mean difference or U-Mann Whitney (according to normal compliance) will be used. All analyzes will be performed with a 95% confidence interval.

Process:

The health professional responsible for carrying out the intervention will be the nurse of the pediatric consultation of the Health Center where the study will be carried out. She is the only nurse in this center, so she will be the only professional to perform the procedure on all subjects participating in the study; in this way the variability in the puncture technique is avoided.

The nurse will recruit potential participants who meet inclusion criteria, informing about the research and answering their possible questions. Once participants wishing to be part of the study have signed the informed consent, they will be coded by numbers. These numerical codes will be linked chronologically to the random sequence previously generated by the sealedenvelopeTM software. Once the nurse knows the group to which the participant belongs, she will perform the corresponding intervention.

The evaluation after the completion of the vaccination procedure will be carried out through self-administered scales (by the child for pain and fear variables, and by the caregiver for sociodemographic and satisfaction variables). In addition, the nurse will record data regarding vaccinations.

The data collection time is estimated at 1 year and a half or until the sample size is reached.

Intervention:

The study groups will be determined by the randomization of the sample into two groups: GI and GC. The GI will use as a distracting measure the viewing of VR experiences adapted to their age with the Oculus Go VR glasses during the puncture. The GC will use habitual non-virtual distracting measures: being in the arms of the main caregiver or maintaining physical contact with him (for example, shaking hands) and / or playing or watching videos with the mobile phone of the parents or legal guardian.

Inclusion Criteria:

• Children aged between 3 and 14 years old, who attend a pediatric nursing office of the Fuensanta Health Center (Valencia) for immunization by vaccine.
• Children who are accompanied by a caregiver (father, mother, legal guardian) during the procedure.
• That both the child and the caregiver understand and speak Spanish.
• That they have consented to participate in the study: in children by verbal consent and in their father, mother, legal guardian, by signing the informed consent document.

Exclusion Criteria:

• Children with sensory problems that prevent the use of RV.
• Children with sensory impairment of pain perception (for example, spina bifida).
• Children who have taken analgesic medication on the day of the puncture, either orally or topically in the puncture area.
• Children with a history of seizures or dizziness.

Only the care giver (nurse) will know the assignment of participants to the treatment groups.
