Why GiveWell funded the rollout of the malaria vaccine

| by Audrey Cooper

Since our founding in 2007, GiveWell has directed over $600 million to programs that aim to prevent malaria, a mosquito-borne disease that causes severe illness and death. Malaria is preventable and curable, yet it killed over 600,000 people in 2021—mostly young children in Africa.

Following the World Health Organization’s approval of the RTS,S/AS01 malaria vaccine (RTS,S) in late 2021, GiveWell directed $5 million to PATH to accelerate the roll out of the vaccine in certain areas of Ghana, Kenya, and Malawi. This grant aimed to enable these communities to gain access to the vaccine about a year earlier than they otherwise would, protecting hundreds of thousands of children from malaria.

Although we’re very excited about the potential of the RTS,S malaria vaccine to save lives, it isn’t a panacea. We still plan to support a range of malaria control interventions, including vaccines, nets, and antimalarial medicine.

In this post, we will:

  • Explain how we found the opportunity to fund the malaria vaccine
  • Discuss why we funded this grant
  • Share our plan for malaria funding moving forward

How much funding does GiveWell expect to raise through 2025?

| by Isabel Arjmand

We’re optimistic that GiveWell’s funds raised will continue to increase in the long run. Over the next few years, we believe our annual funds raised are more likely to stay relatively constant, due to a decrease in expected funding from our largest donor, Open Philanthropy, offset by an expected increase in funding from our other donors.

In November 2021, we wrote that we were anticipating rapid growth and aiming to influence $1 billion in 2025. Now, our best guess is that we’ll raise between $400 million and $800 million in 2025 (for comparison, we raised around $600 million in 2022). We now think it’s possible but unlikely that we’ll raise close to $1 billion in 2025, and we also think it’s possible but unlikely that our funds raised in 2025 will be substantially lower (e.g. around $300 million) than they were in 2022.

We’re excited about the impact we can have at any of those levels of funding, and we’ll be continuing to direct as much funding as we can raise to the most cost-effective opportunities we can find.

The winners of the Change Our Mind Contest—and some reflections

| by Isabel Arjmand

In September, we announced the Change Our Mind Contest for critiques of our cost-effectiveness analyses. Today, we’re excited to announce the winners!

We’re very grateful that so many people engaged deeply with our work. This contest was GiveWell’s most successful effort so far to solicit external criticism from the public, and it wouldn’t have been possible without the participation of people who share our goal of allocating funding to cost-effective programs.

Overall, we received 49 entries engaging with our prompts. We were very happy with the quality of entries we received—their authors brought a great deal of thought and expertise to engaging with our cost-effectiveness analyses.

Because we were impressed by the quality of entries, we’ve decided to award two first-place prizes and eight honorable mentions. (We stated in September that we would give a minimum of one first-place, one runner-up, and one honorable mention prize.) We also awarded $20,000 to the piece of criticism that inspired this contest.

Winners are listed below, followed by our reflections on this contest and responses to the winners.
