Virtual reality (VR) is a technology that is capable of entertaining and distracting the user. Among its many applications, we find the improvement of pain management and the reduction of anxiety in patients undergoing medical interventions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>We aim to publish the protocol of a clinical trial for the reduction of pain and anxiety after the administration of 2 vaccines in children aged 3 to 6 years.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We will conduct a randomized, parallel, controlled clinical trial with 2 assigned groups. The intervention group will wear VR goggles during the administration of 2 vaccines, while the control group will receive standard care from a primary care center for the procedure. Randomization will be carried out by using the RandomizedR computer system\u2014a randomization tool of the R Studio program. This trial will be an open or unblinded trial; both the subjects and the investigators will know the assigned treatment groups. Due to the nature of the VR intervention, it will be impossible to blind the patients, caregivers, or observers. However, a blind third-party assessment will be carried out. The study population will include children aged 3 to 6 years who are included in the patient registry and cared for in a primary care center of the region of Central Catalonia. They will receive the following vaccines during the Well-Child checkup: the triple viral+varicella vaccine at 3 years of age and the hepatitis A+diphtheria-tetanus-pertussis vaccine at 6 years of age.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The study is scheduled to begin in January 2022 and is scheduled to end in January 2023, which is when the statistical analysis will begin. As of March 2022, a total of 23 children have been recruited, of which 13 have used VR during the vaccination process. In addition, all of the guardians have found that VR helps to reduce pain during vaccination.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>VR can be a useful tool in pediatric procedures that generate pain and anxiety.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>International Registered Report Identifier (IRRID)<\/jats:title>\n                    <jats:p>PRR1-10.2196\/35910<\/jats:p>\n                  <\/jats:sec>","DOI":"10.2196\/35910","type":"journal-article","created":{"date-parts":[[2022,1,17]],"date-time":"2022-01-17T11:41:33Z","timestamp":1642419693000},"page":"e35910","source":"Crossref","is-referenced-by-count":7,"title":["Use of Virtual Reality in the Reduction of Pain After the Administration of Vaccines Among Children in Primary Care Centers: Protocol for a Randomized Clinical Trial"],"prefix":"10.2196","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1662-6863","authenticated-orcid":false,"given":"Mercedes","family":"de la Cruz Herrera","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9128-9580","authenticated-orcid":false,"given":"A\u00efna","family":"Fuster-Casanovas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7379-4671","authenticated-orcid":false,"given":"Queralt","family":"Mir\u00f3 Catalina","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5320-351X","authenticated-orcid":false,"given":"Mireia","family":"Cigarr\u00e1n Mensa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0855-3254","authenticated-orcid":false,"given":"Pablo","family":"Alc\u00e1ntara Pinillos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5144-9287","authenticated-orcid":false,"given":"Isabel","family":"Vilanova Guitart","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8223-2398","authenticated-orcid":false,"given":"Sergi","family":"Grau Carri\u00f3n","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3527-4242","authenticated-orcid":false,"given":"Josep","family":"Vidal-Alaball","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2022,4,7]]},"reference":[{"issue":"12","key":"ref1","first-page":"932","volume":"63","author":"Arane, K","year":"2017","journal-title":"Can Fam Physician"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.pedn.2011.08.001"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.3390\/children4070052"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinthera.2009.07.022"},{"key":"ref5","unstructured":"Immunization stress-related response: a manual for program managers and health professionals to prevent, identify and respond to stress-related responses following immunizationWorld Health Organization20192022-03-10https:\/\/apps.who.int\/iris\/bitstream\/handle\/10665\/330277\/9789241515948-eng.pdf?sequence=1&isAllowed=y"},{"issue":"3","key":"ref6","first-page":"201","volume":"71","author":"Majstorovic, M","year":"2004","journal-title":"J Dent Child (Chic)"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1017\/s0033291798007144"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0722.2006.00335.x"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016\/j.vaccine.2012.05.011"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1080\/16506073.2016.1157204"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1503\/cmaj.092048"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1002\/14651858.CD010686.pub2"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1093\/pm\/pnx109"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1097\/BCR.0000000000000019"},{"key":"ref15","unstructured":"Protocol d'activitats preventives i de promoci\u00f3 de la salut a l'edat pedi\u00e0tricaDirecci\u00f3 General de Salut P\u00fablica.
