Abstract

fetched live from OpenAlex

Mass vaccination clinics efficiently vaccinate large numbers of people. The CARD system (Comfort, Ask, Relax, Distract) is a vaccination delivery framework that can improve the experiences of vaccine recipients and providers. This two-stage hybrid effectiveness-implementation study implemented and sustained CARD in university-based vaccination clinics involving pharmacy student vaccinators. Stage 1 was a before-and-after study conducted across four COVID-19 vaccination clinics in November-December, 2022. Stage 2 was a single cohort study whereby CARD was sustained across four COVID-19/influenza vaccination clinics in November, 2023. In both stages, vaccine recipients rated experiences relative to last vaccination (primary outcome) and symptoms (pain, fear, dizziness) using surveys. Pharmacy student vaccinators completed attitudes and behaviors surveys; a subsample participated in focus groups. In Stage 1, more vaccine recipients in the after period (vs. before) reported a better vaccination experience relative to their last vaccination (64.0% vs 33.6%; p < .001; n = 181). Fear and pain were lower (1.1 vs. 1.7, p = .03; and 1.6 vs. 2.1, p = .02, respectively). In Stage 2, 57.4% (95% CI: 53.1%-61.6%; n = 542) of vaccine recipients reported a better experience. Across stages, pharmacy students had positive attitudes about acceptability, feasibility, and sustainability of CARD and reported high fidelity with CARD-recommended interventions. CARD is recommended for university-based vaccination clinics to improve vaccine recipient and provider experiences.

Not 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.
