Oculorespiratory Syndrome After Influenza Immunization in Children
Bibliographic record
Abstract
BACKGROUND: During the 2000-2001 season, an oculorespiratory syndrome (ORS) was identified in association with 1 manufacturer's influenza vaccine in Canada. ORS included bilateral red eyes, facial edema or respiratory symptoms beginning within 24 hours of influenza immunization. Few reports involved children. We assessed the rate of ORS in a pediatric cohort. METHODS: In February 2001, invitation to participate in an influenza vaccine safety survey was sent to the parents of children who attend a diabetes clinic. A questionnaire elicited influenza immunization history and adverse event experience beginning within 1 day of vaccination for the child with diabetes and up to 3 siblings. Follow-up telephone interviews collected information from those who failed to return a questionnaire by mail. RESULTS: Of the 959 households sent a questionnaire, 780 participated (81%). Among 780 children with diabetes, 418 (54%) received influenza vaccine in 2000. Adverse event experience was collected from an additional 242 immunized siblings. Among immunized children, 13% (95% confidence interval, 10-16%) experienced ORS, consisting primarily of respiratory symptoms. The majority (72%) resolved within 2 days. There was association between ORS and first time receipt of influenza vaccine (OR 2.7; 95% confidence interval, 1.6-4.4). Fewer parents of ORS-affected compared with unaffected children indicated that they were likely or very likely to have their child revaccinated (87 versus 97%; P < 0.001). CONCLUSIONS: In 2000-2001, children experienced ORS in Canada at a rate comparable with that of adults. ORS should be incorporated into influenza vaccine safety monitoring and discussed with parents, especially those contemplating influenza vaccine for their child for the first time.

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.
