The purpose of our study was to assess these rates.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Materials and Methods</h3>\u0000 \u0000 <p>We reviewed vaccination records of pediatric recipients of heart, kidney, and liver transplants at Mayo Clinic, Rochester, MN, who received a transplant between January 2011 and December 2021. All SARS-CoV-2 vaccines and doses of TC received on or before September 1, 2022, the date of approval of the bivalent SARS-CoV2 vaccine, were included. We also assessed whether patients had been seen by an infectious diseases physician (ID) in the preceding 6 months.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Our study included 110 patients: 47 kidney, 36 heart, and 27 liver transplant recipients. All vaccine doses recorded were monovalent SARS-CoV-2 vaccines. Sixty-eight (61.8%) patients received at least one vaccine. This varied by age group, with f of ≥12 years olds, 40.9% of 5–11 year olds and 14.3% of under 5 year olds (<i>p</i> = 0.001). Seven patients (6.4%) were up-to-date (UTD) for age. There was no difference in UTD status by organ type (<i>p</i> = 0.335). Patients who saw ID were significantly more likely to be UTD (13.2% versus 2.8%; <i>p</i> = 0.047). Among those eligible, 14 (18.2%) received TC, with rates not different based on transplanted organ type (<i>p</i> = 0.158) or whether they saw ID (<i>p</i> = 0.273).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Despite the availability of vaccines, nearly 40% of pediatric solid organ transplant recipients remained unvaccinated against SARS-CoV-2 at time of the bivalent vaccine release. Less than a fifth of eligible patients received TC. Strategies to increase uptake of SARS-CoV-2 vaccines as well as adjunctive agents among this vulnerable group should be further explored.</p>\u0000 </section>\u0000 </div>","PeriodicalId":10467,"journal":{"name":"Clinical Transplantation","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141733710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
