Abstract
In pediatric ages, sublingual immunotherapy (SLIT) allows allergic children to approach the inhaling desensitizing therapy. However, SLIT causes quite a few compliance problems and sometimes it is difficult to carry it out for the required long term. The alternative is subcutaneous immunotherapy (SCIT), commonly performed with a syringe. This technique hasn't changed much in time and it is not without risks or discomfort. This has led to the search for alternative ways of vaccine administration, in order to reduce discomfort to children by improving compliance and diminishing the potential risks of adverse reactions. OBJECTIVE The study aimed to assess the patient's perceived pain and the safety of a new way of administration of SCIT, with a needleless device. METHODS Children with grass or mite-induced allergic rhinoconjunctivitis and/ or bronchial asthma were prescribed a glutaraldehyde-polymerized allergenic extract (Allergovac Polymeryzed, Bial Aristegui, Italy). Each dose was divided in two parts: half injected with the traditional syringe (dose A), half in the other arm with a needleless device (Injex, Greytree, Ross on Wye, UK; dose B). Patients were blindfolded. The perceived pain and the difficulties of the procedure were registered on a dedicated VAS scale immediately (time 1) and 20 minutes after the first injection (time 20). Also, we evaluated the occurrence of occasional adverse events during such procedure and we assessed the perceived difficulty by the doctor administering with such method. RESULTS 39 patients, aged 5-18 years, were recruited and assessed. All patients completed the study, which involved 468 grass pollen AIT SCIT doses, of which 234 with needleless device. At time 1, the use of the needleless device led to an 88% reduction of the pain perception average rate (from 16,8 to 1,97). The difficulty for the technician to make the inoculum was also analyzed (expressed by an increasing rate, from 0 to 4). In all 6 doses, for each child, the difficulty rate 2 relates to an almost constant number of patients, while the highest difficulty rates (grade 3 and grade 4) gradually decrease (until they disappear).

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 it
