Neurological adverse events following COVID-19 vaccination among Canadians referred to the special immunization clinic network
Bibliographic record
Abstract
Neurological adverse events have been reported rarely following COVID-19 vaccination. This study describes the characteristics of adolescents and adults assessed in the Canadian Special Immunization Clinic (SIC) Network for neurological adverse events following immunization (AEFIs) and outcomes of revaccination. Among 60 participants enrolled from January 2021 to February 2023, paresthesia/anesthesia was the most common diagnosis (15/60; 25.0 %), followed by Bell's Palsy (6/60; 10.0 %). Twenty-eight percent (17/60) of participants were hospitalized for their AEFI. Revaccination was recommended to 32/46 (69.6 %) participants due for subsequent doses when assessed in the SIC. Twenty-three participants were revaccinated and 4/23 (17.4 %) had recurrent symptoms of the AEFI; three were milder than the first event and none required hospitalization. Revaccination was generally safe in selected patients after a neurological AEFI. Expert assessment of patients with neurological AEFIs may help to support further vaccination.

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.
