Sustainability of humoral responses to varicella vaccine in pediatric transplant recipients following a pretransplantation immunization strategy
Bibliographic record
Abstract
Varicella infections pose serious challenges for organ transplant recipients. To determine the safety and immunogenicity of the OMVV and determine the maintenance of OMVV responses in transplanted subjects at varying periods of immunosuppression within the first two yr following transplantation. Eligible subjects given a two-dose OMVV pretransplantation were monitored for AE. Antibody levels were assessed at baseline, six wk post-OMVV, pretransplantation and up to 24 months post-transplantation. Seroprotection was defined as >or=5 gpEU. Twenty-one seronegative children were vaccinated. Following 42 doses, no vaccine-related serious AE occurred. Mab_titer were 17.8 (5.7-910.2) and 183.5 EU (18.8-8116.4) at six and 12 wk, respectively (p < 0.0001). Fourteen (66.7%) participants were transplanted at a median of 16 months (1.5-56) following OMVV and had Mab_titer of 27.2 EU (9.0-236.2) just prior to transplantation. Of 11 who had post-transplantation serology, seroprotection was sustained at three, six and 12 months post-transplantation in 10/11, 12/12 and 8/10 subjects. In five of six subjects with two-yr follow-up, antibody levels remained seroprotective. No breakthrough varicella infections occurred. The receipt of OMVV prior to transplantation induced humoral responses which persisted in the early months following transplantation and up to two yr post-transplantation and was not associated with any serious adverse consequences.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
