Medical aid where it's needed most — independent, neutral, impartial.

Médecins Sans Frontières/Doctors Without Borders (MSF) is a private international association founded in 1971. The association is made up mainly of doctors and health sector workers and is also open to other professions which might help in achieving its aims. Our mission is to provide lifesaving medical care to those most in need.

All MSF members agree to honor the following principles:

MSF provides assistance to populations in distress, to victims of natural or man-made disasters, and to victims of armed conflict. They do so irrespective of gender, race, religion, creed, or political convictions.

MSF observes neutrality and impartiality in the name of universal medical ethics and the right to humanitarian assistance. MSF claims full and unhindered freedom in the exercise of its functions.

Members undertake to respect their professional code of ethics and to maintain complete independence from all political, economic, or religious powers.

As volunteers, members understand the risks and dangers of the assignments they carry out and make no claim for themselves or their assigns for any form of compensation other than that which the association might be able to afford them.

Animal Charity Evaluators helps people help the most animals.

Animal Charity Evaluators (ACE) is a 501(c)(3) nonprofit registered in the United States with a globally distributed team dedicated to impactful animal advocacy. Our mission is to find and promote the most effective ways to help animals. We work toward that mission by evaluating charities, sharing our findings, awarding grants to organizations and promising projects, and fundraising for our recommended charities and grantees. Our organization opposes all systems of oppression and recognizes that they are connected and mutually reinforcing. Ultimately, our vision is a world in which no individual is given less than full moral consideration on the basis of any morally irrelevant feature of their identity, including species membership.

ACE is proud to be considered a leader in the effective animal advocacy movement. Our research comparing the different approaches to reducing the suffering of animals has led to rigorously reviewing charities that work to end factory farming and create meaningful change for farmed and wild animals. Through our Recommend Charity Fund, we have raised and distributed $8.1M to our effective recommended charities. Our Movement Grants program has awarded $5.3M to promising animal advocacy projects around the globe. Since we began tracking this metric in 2014, we estimate that ACE has helped to influence nearly $60M within the animal advocacy movement.

Thanks for helping ACE help animals!

Evidence Action scales evidence-based and cost-effective programs to reduce the burden of poverty. 

Our organization was founded in 2013 to address a big gap in the fight against global poverty--many of the most promising interventions are either implemented at a very small scale, or not at all. We set out to address this gap by building programs that would scale evidence-based and cost-effective interventions, leading to significant improvements in quality of life for hundreds of millions of people. 

Our model worked. In less than a decade, our two flagship programs, the Deworm the World Initiative and Dispensers for Safe Water, have grown to measurably impact over 280 million people each year. This success is achieved through the dedication and talent of our staff, the hard work of our partners, and the commitment of our supporters.

By 2024, we seek to double our impact. We are strengthening and expanding our existing programs, and working to identify a new generation of evidence-based and cost-effective interventions that we can scale to reach millions more. 

We currently operate three programs:

Dispensers for Safe Water 

Dispensers for Safe Water program delivers free and reliable access to safe water for 4 million people in rural Kenya, Uganda, and Malawi.
In rural parts of low-income countries, most water sources are untreated, meaning that water is not safe to drink directly from the source. Our uniquely-engineered chlorine dispensers are installed next to commonly-used water sources, enabling people to treat their water using a safe and pre-measured dose of chlorine. The chlorine stays active for 2-3 days, ensuring water doesn’t get recontaminated even when stored at home. Adding diluted chlorine to water is a WHO-endorsed approach to improving water quality. 
Dispensers for Safe Water is a cost-effective solution - just over $1.00 delivers safe water access to one person for an entire year. In 2019, our program averted over 380,000 cases of diarrhea among children, one of the main causes of childhood mortality in the countries where we operate.

Deworm the World Initiative

Deworm the World Initiative helps governments launch, scale, and sustain school-based deworming programs.

Over 868 million children globally are at risk of contracting parasitic worm infections. If left untreated, infections can lead to anemia, malnourishment, and impaired mental and physical development—ultimately affecting children’s educational outcomes and income as adults.Our program brings free treatment to children at their schools instead of placing the burden on the families to obtain it. We partner with governments to regularly treat all at-risk children in places where at least 20% are infected with worms, as recommended by the World Health Organization.  

Rigorous research shows that deworming leads to significant improvements to children’s health, education, and long-term wellbeing. In 2019, we helped governments treat over 280 million children in India, Kenya, Nigeria, Ethiopia, and Pakistan for less than US 50 cents per treatment.

Accelerator:  
 
Evidence Action Accelerator is our engine for new program development that selects, optimizes, and scales interventions with the highest potential to measurably improve the lives of millions of people in the world’s poorest places.  

Each intervention considered by the Accelerator must undergo a multi-stage process of program development, taking it from an evidence-based concept to a fully-developed solution that can be replicated in multiple geographies. We look for three critical aspects during the assessment process: rigorous evidence, cost-effectiveness, and potential for scale. 

We are currently accelerating two promising health solutions: working with the Liberian government to detect and treat maternal syphilis, with the aim of preventing thousands of child deaths and disabilities each year; and supporting the Indian government to improve the distribution of iron and folic acid supplementation to millions of children and adolescents —treating iron deficiency anemia, one of the main causes of disability in the country.

We provide cash incentives for childhood vaccinations. It’s one of the most cost-effective ways known to save lives.


Childhood vaccines prevent an estimated 2 to 3 million deaths every year. They are recognized as one of the most cost-effective child health interventions in low-income countries. Yet, an estimated 25 million children missed out on vaccination in 2021, 5.9 million more than in 2019 and the highest number since 2009. 

In Nigeria, 40% of under-five deaths are from vaccine-preventable diseases – low immunisation rates are a significant contributor to its high under-five mortality rate (111 deaths per 1,000 live births).

Delivering unconditional cash directly to the world's poorest households via secure mobile transfers. 

Since 2009, GiveDirectly has delivered more than $580 million in unconditional cash transfers to families in need. These one-time cash transfers allow recipients to invest in what they need most and have been shown to improve their earnings, children’s school attendance, health, nutrition, and mental well-being.
 
GiveDirectly uses government data to target villages where most or all residents are living in extreme poverty, defined by the World Bank as earning under $2.15/day. In-country GiveDirectly staff enroll one member of each household in the entire village to receive a one-time transfer of about $1,000 USD sent in two installments using mobile money. Recipients can then withdraw the mobile funds as cash with local agents and use the funds to invest in what they need – whether it’s on starting a business, education, making their home safer/sturdier, healthcare, or livestock.
 
GiveDirectly uses rigorous experimental research (randomized controlled trials) to measure the impact of their unconditional cash programs and answer public policy questions, generating evidence on key design and implementation questions across varied contexts. You can find over 300 studies on the positive impacts of cash transfers in GiveDirectly’s Cash Research Explorer.

One of GiveWell's top charities for the past several years, AMF provides anti-malarial bednets to people in need. 

From Givewell: 
What do they do? AMF (againstmalaria.com) provides funding for long-lasting insecticide-treated net (LLIN) distributions (for protection against malaria) in developing countries. (More)

Does it work? There is strong evidence that distributing LLINs reduces child mortality and malaria cases. AMF conducts post-distribution surveys of completed distributions to determine whether LLINs have reached their intended destinations and how long they remain in good condition. AMF's post-distribution surveys have generally found positive results but have some methodological limitations. (More)

What do you get for your dollar? We estimate that the cost to purchase and distribute an AMF-funded net is $4.95, or $4.65 excluding in-kind contributions from governments. The numbers of deaths averted and other benefits of distributing LLINs are a function of a number of difficult-to-estimate factors, which we discuss in detail below. (More)

Is there room for more funding? We believe that AMF is likely to be constrained by funding. We estimate that AMF could use up to an additional $37.8 million to support LLIN distributions that will occur between now and late 2023. 

AMF is recommended because of its:

Focus on a program with excellent evidence of effectiveness and cost-effectiveness.
Processes for ensuring that nets reach their intended recipients and monitoring whether they remain in homes and in good condition over the long-term.
Room for more funding – we believe AMF will be able to use additional funds to deliver additional nets.
Transparency – AMF shares significant information about its work with us and we are able to closely follow and understand its work.
