Help end malaria, one donation at a time.

Younos and Friends Help End Malaria

We're getting married on April 18th, 2026 in the West of Ireland!

Your presence at our wedding is the best gift we could ask for - especially since we're asking you to travel. But if you'd like to give something, we'd be thrilled if you made a donation here instead. If you do contribute, please add a private note so we know to thank you!

**Why the GiveWell Top Charities Fund?**

GiveWell identifies the most effective charities for saving and improving lives. Their top charities deliver proven, cost-effective programmes in the world's poorest communities - things like:

- Distributing malaria nets that save children's lives
- Providing vitamin A supplements to prevent child mortality
- Delivering direct cash transfers to families living in extreme poverty

Every donation goes directly to where it can do the most good, based on rigorous evidence.

Thank you for being part of our celebration, and for considering supporting this incredible work.

With love, Cillian & Aisling ❤️

Prevention, control and treatment of malaria and other communicable diseases among vulnerable populations.

Malaria Consortium US, Inc. (MC-US) is a registered 501(c)(3) public charity and shares the mission of Malaria Consortium, a globally recognized organization committed to reducing deaths and illnesses caused by malaria and other preventable and treatable diseases across Africa and Asia.

Our mission is to save lives and improve health in Africa and Asia through evidence-based programs that tackle malaria and other priority diseases while advancing universal health coverage (UHC). In the US, we build partnerships with foundations, donors, and philanthropic organizations to ensure that every contribution makes a lasting impact for those most in need.

As a leader in malaria control and elimination, our work focuses on interventions such as seasonal malaria chemoprevention (SMC), malaria vaccines, disease surveillance, and integrated child health services. We work in collaboration with governments, communities, and health systems to improve access to essential healthcare and strengthen delivery of services in underserved and hard-to-reach areas.

As a leader in interventions such as chemoprevention and vector control, we rely on evidence and our expertise to deliver established interventions, influence other effective interventions and guide new strategies to reduce the burden of malaria, pneumonia, dengue, malnutrition and diarrhea. We work with communities and all levels of the health system to improve access to and demand for primary healthcare services and overall quality of care.

Our tailored interventions seek to improve equity by providing quality, affordable health services to marginalized populations (particularly women and girls and those living in hard-to-reach areas). To ensure barriers to achieving UHC are addressed and to encourage sustainability, we work closely with governments to integrate our programs within existing health systems and structures in the countries in which we work.

We promote disease surveillance as a core intervention to engage communities to improve the quality and accessibility of routine health information by using digital tools and approaches that strengthen the linkages between case-level data and national health information systems. We combine capacity development at community level with the use of innovative tools and platforms to enhance local capabilities to interpret and use these data most effectively.

All of our work is informed by our core values: accountability, integrity, dignity and equity.

Malaria Consortium

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.

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


New Incentives’ mission is to save lives in a way that does the **most good per dollar**.
Guided by evidence, we provide cash incentives to increase childhood vaccination rates.

- We [raise awareness](https://www.newincentives.org/blog-posts/awareness-activities) about the benefits of childhood vaccinations.
- We [provide cash incentives](https://www.newincentives.org/blog-posts/a-day-in-the-life-abubakar-aliyu-field-officer) at government clinics after children receive vaccinations.
- We [help improve the vaccine supply chain](https://www.newincentives.org/blog-posts/supporting-government-partners-with-vaccine-supply-efforts) to ensure enough vaccines are available at clinics.

Together, these efforts are proven to double vaccination rates and save lives.

**The Reviving Another's Next Act Movement**

Most of us grow up believing saving a life is a superpower reserved for front-line medical staff and billionaire philanthropists. The RANA Movement is here to change that, using biology and high-impact giving to show how accessible saving a life really is.

Our mission maps out two distinct paths:

**The Biological Path**
Your body is an engine of pure abundance. We raise awareness for free, life-saving actions that almost no one talks about — like a simple cheek swab for bone marrow registries, or donating the plasma and platelets your body naturally replenishes for free. It costs you nothing to give someone their next act.

This abundance carries forward even when your story ends. By registering as a post-death organ and tissue donor, your final act can save up to eight lives — and revive the next chapter of up to 75 more. It is a completely costless passing of the torch that ensures your legacy is one of life.

**The Financial Path**
The data is real. You don't need a medical degree or a billion dollars. A regular person, dedicating their regular work to this goal, can statistically save a real human life. Based on GiveWell's own published cost-effectiveness research, a relatively small donation can save a life through their highest-confidence programs. See their current numbers at givewell.org.

**Two paths. Both within reach. Both impossible to un-know once you're here.**

The RANA Movement

Giving back is a core value of ours. We understand just how fortunate we've been to have had good health and our basic needs met throughout our lives. As a result, we created this fundraiser so that our special day can also have a positive impact on others around the world who need help. 

We have no expectations for gifts or contributions from any of our guests, but if you would like to you can donate to this fundraiser here. All funds will go to [Givewell's Top Charities Fund.](https://www.givewell.org/top-charities-fund) Givewell is an organization that conducts rigorous research into the impact that various charities make. We find Peter Singer's arguments around Effective Altruism to be persuasive and are confident that Givewell's Top Charities Fund does an excellent job of maximizing the impact that each dollar donated can have.

Thank you for any and all donations, and thank you again for being a part of our special day!
