Fatal Adverse Pulmonary Reaction in Calves after Inadvertent Intravenous Vaccination
Bibliographic record
Abstract
Fatal adverse reactions to vaccination are uncommon and poorly documented. To our knowledge, this is the first case report of fatal adverse reaction to an inadvertent intravenous vaccination in three calves vaccinated against respiratory (Somnustar Ph) and clostridial (Tasvax 8) diseases. All three calves had severe acute interstitial pneumonia with multifocal pulmonary hemorrhages that resulted in fatal respiratory failure. Qualitatively, the pulmonary lesions in these calves were similar to those in septicemic/endotoxemic calves; however, the severity and extensity of pulmonary hemorrhages were of a higher degree than those usually observed in clinical septicemia/endotoxemia. In addition, approximately 30% of the arterioles and small arteries were surrounded by hemorrhages, which occasionally extended around adjacent bronchioles. A unilateral peri-jugular hematoma with recent transmural perforation of jugular vein found in all three calves was believed to have been caused by the injection needle during vaccination, and the fatal pulmonary changes were believed to have been secondary to the intravenous injection of vaccine.

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.
