A policy roadmap for sustainable mass-testing
Bibliographic record
Abstract
Population-wide mass testing with affordable self-tests can drastically reduce lives lost and minimize economic and societal costs during pandemics, especially if deployed before vaccines. During COVID-19, however, the development of self-test manufacturing and distribution capacity lagged behind vaccine rollout and was dismantled once surges subsided, returning us to a prepandemic state. As no new capacity has since been secured, future mass-testing would again face costly delays. To mitigate this risk, we propose a policy roadmap for an economically viable mass-testing system that can be sustained between crises and rapidly scaled during emergencies. Public investment in R&D to improve the sensitivity of affordable self-tests-not to achieve a single benchmark, but to advance point-of-need technologies across medical and nonmedical applications-is essential. Improved sensitivity would enable new uses in routine health screening, food safety, and environmental monitoring, generating steady demand and production capacity that can expand as needed. This demand would support a robust system anchored by four mutually reinforcing pillars: scalable manufacturing, real-time data infrastructure, predictive analytics, and sustainable financing. Prioritizing sensitivity can transform mass testing from a reactive measure into a durable public health foundation.

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.
