🎧 Most of GiveWell's grantmaking focuses on preventing child deaths from widespread conditions like malaria. But as our research capacity has grown, so has our ability to evaluate and fund programs that look different from our typical work, including treatments for disabilities like clubfoot—an area we’ve long wanted to explore.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld speaks with Program Officer Meika Ball about our grant to MiracleFeet, which expands access to clubfoot treatment in countries where most children who need care go untreated. They discuss how we assessed the cost-effectiveness of this kind of grant, and what Meika learned during a recent site visit to Côte d'Ivoire, including some reflections recorded during the visit.

🎧 Vitamin A supplementation has one of the strongest evidence bases of any program we've evaluated. But when you dig in, the evidence is more complicated than it looks.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld speaks with Senior Researcher Stephan Guyenet about the evidence for vitamin A supplementation, the hard questions that remain, and how our expanded research capacity is helping us go deeper so we can direct funding more effectively.

🎧 In 2025, GiveWell made 18 grants totaling approximately $39 million specifically aimed at generating information to improve our future grantmaking—funding research, piloting program variations, and scoping new opportunities.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld and Program Director Julie Faller discuss this work, including pilots testing variations on cash transfers with GiveDirectly, a trial of door-to-door diarrhea treatment delivery in Nigeria, and a survey to better understand a flour fortification program in India.

🦟 Members of our malaria research team recently attended the Joint Meetings of the SMC Alliance and the Alliance for Malaria Prevention in Kampala, Uganda.

We've been expanding our networks by regularly attending conferences to connect with government officials, other funders, and implementing organizations. We're excited to apply what we've learned and the relationships we've built to strengthen our grantmaking.

🎧 Sometimes, even if a program we fund is doing a lot of good, it may not have the impact per dollar we expected. As our research team has grown, we've become better able to collect and analyze data on our grant performance. In most cases, results are consistent with what we anticipated—but not always.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld and Senior Program Officer Erin Crossett discuss how we responded when early data on Evidence Action's Dispensers for Safe Water in Malawi and Uganda indicated the program wasn't reaching as many people as estimated. What we learned by digging in deeper and commissioning independent surveys changed our mind on the program and helped improve our research for future funding decisions.

📣 Two new RFIs now open!

GiveWell has made over $200M in vaccination-related grants and over $41M in iron fortification and supplementation grants. Now, we’re looking to expand our funding in both areas.

Vaccination outreach RFI: Seeking targeted outreach or mobile vaccination programs that aim to increase uptake of routine vaccinations for children under 2 in the DRC, Nigeria, or Somalia.

Anemia control RFI: Seeking programs that reduce iron deficiency anemia through large-scale iron fortification, supplementation, or biofortification in Africa.

We’re excited to explore how to reach even more people in low- and middle-income countries with programs to save and improve lives.

🗓️ Submissions for both RFIs are due March 27.

GiveWell is launching two new requests for information (RFI) to expand GiveWell’s funding for vaccination outreach and anemia control programs.

🎧 GiveWell has supported vaccination programs since 2015, directing over $200 million in related grants. We've been growing our vaccines team and expanding our approach, shifting from finding individual programs to asking a bigger question: What's preventing children from getting vaccinated, and how can we address it?

In this episode, GiveWell CEO and co-founder Elie Hassenfeld and Senior Program Officer Natalie Crispin discuss how our research approach has evolved and what it means for helping more children access life-saving vaccinations

We're taking proactive steps to improve the likelihood of success—and the opportunities for learning—across our water chlorination pilot programs. 💧

Aquaya, a specialist water research organization, will support the implementing partners in working with external survey firms to collect data before and after the pilots to assess the impact of the programs. What we learn from this data will shape our future water grantmaking.

17 pilots. Diverse contexts. One question: Which chlorination approaches have the most promise?

Aquaya is honored to collaborate with as an independent monitoring and evaluation partner for a portfolio of 17 chlorination pilots spanning six African countries.

Our role: Ensure consistent, comparable, rigorous data are collected so we can identify what works.

✅ Standardized measurement protocols
✅ Real-time data quality assurance
✅ Cross-portfolio analyses
✅ Evidence to inform future investments

Comparable data. Bigger impact.

🎧 Seasonal malaria chemoprevention is one of the most cost-effective programs GiveWell has identified—but in eastern and southern Africa, we have substantial uncertainties about drug effectiveness.

That’s why we’re funding the CHAMP trial, which is, to our knowledge, the largest individually randomized trial of malaria chemoprevention drugs ever conducted.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld and Senior Researcher John Macke discuss what we hope to learn and how it could shape our malaria grantmaking.
