## Evidence notes

GiveWell rates evidence as exceptionally strong based on an RCT of New Incentives’ program plus ongoing monitoring (New Incentives review; Top Charities page).

## Key uncertainties

- Whether vaccine efficacy is lower in Nigeria than in other evidence settings (GiveWell NI review).
- Accounting for vaccination-rate increases that would have occurred anyway (GiveWell NI review).
- Fraud risk inherent to cash-handling programs; some federal-government opposition to the model (GiveWell NI review).
- Rising vaccine stockouts for some indirectly incentivized vaccines as program scaled (GiveWell NI review).

## Fungibility notes

Program operates in government clinics; GiveWell discusses displacement/supply-side risks and government relationships in the New Incentives review.

## Cost-effectiveness notes (do not treat as verified without citation_urls)

GiveWell 2022-2024 avg ~$4500/life; ~$146/infant (New Incentives).
