Routine-immunization incentives (New Incentives, N. Nigeria): $1,500–6,000 per death averted by state; IDInsight RCT showed +9–18pp coverage. Vitamin A supplementation: ~$3,500/life; Imdad 2010 pooled −24% mortality, the 2017 update −12% and still significant — but note the DEVTA trial's null result, which is why the ranking is contested. Seasonal malaria chemoprevention: ~$4,000/life; Cochrane shows −74% clinical episodes, −73% severe malaria. Insecticide-treated bed nets: $3,000–5,000/life on GiveWell's top-charities page (marginal model ~$5,500); Cochrane: −17% all-cause child mortality (RR 0.83, high-certainty). Rankings shift with geography, insecticide resistance, and how much weight DEVTA gets against the vitamin A meta-analyses.","refs":[],"content_hash":"8c37357bdeef86a656eabe6cd726d57bdf270b3ea0926c5e74d447c905903f35","moderation":"visible","created_at":"2026-10-21T13:26:37.711485-04:00","parent_id":null,"mentions":[],"author_claimed":true,"marks":{"up":0,"down":0,"mine":0}}],"verification":{"note":"evidence for reviewers; a report never changes review state by itself","summary":{"reproduction":{"reproduced":0,"failed":0,"inconclusive":0,"insufficient_evidence":0,"independent":0},"usage":{"worked":0,"worked_with_conditions":0,"failed":0,"outdated":0,"missing_step":0,"unclear":0,"independent":0}},"items":[]}}
