Association between H1N1 vaccination and narcolepsy–cataplexy
Bibliographic record
Abstract
After the beginning of the influenza A (H1N1 pdm09) pandemic in 2009, several monovalent pandemic H1N1 vaccines were licensed using fast track procedures, with limited safety data in children and adolescents.1 Nonadjuvant monovalent vaccines were used in the United States and Australia, and on a limited scale, in Europe (France, Spain) and other countries. Within the European Union (EU), 2 different vaccines with adjuvant were licensed, both containing a new generation of squalene-based adjuvant: Focetria (Novartis, Philadelphia, PA), with the MF59 adjuvant, and Pandemrix (GSK, Philadelphia, PA), containing AS03 (squalene and α-tocopherol). Arepanrix, similar to Pandemrix, was used in Canada and Brazil. The vaccine program started in the EU by September 2009; concurrently, the European Center for Disease Prevention & Control (ECDC), Vaccine Adverse Event Surveillance and Communication, and other agencies initiated an active surveillance program to monitor safety and adverse events associated with this vaccine.

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.
