Abstract
Until recently Haemophilus influenzae type b (Hib)was a leading cause of meningitis, epiglottitis andother invasive infections in children, affecting about 1 child in 250 by 5 years of age.1 The risk of infection was highest among children 6–24 months of age. Antibod-ies directed against the Hib capsular polysaccharide (poly-ribosyl ribitol phosphate, PRP) form the basis of protec-tion. PRP protein conjugate vaccines that elicit anti-PRP responses in young infants have been used in Canada since 1992. Doses are recommended at 2, 4 and 6 months of age to establish protection and at 18 months to reinforce it. Since 1995 all provinces have used the same Hib vaccine (a PRP–tetanus protein conjugate [PRP-T], produced by Aventis Pasteur), in combination products based on whole-cell pertussis vaccines (from 1995 to 1997) or acellular per-tussis vaccines (1998 to the present). Invasive Hib infections have been monitored since 1992

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
