Each year, Bill and Melinda Gates write a letter about the work they’re doing with the Bill and Melinda Gates Foundation. In 2006, Warren Buffett donated more than billion to their foundation, which effectively doubled its available resources. This year’s letter from the Gateses is addressed to Buffett and details the return on his investment so far.
Bill: If we could show you only one number that proves how life has changed for the poorest, it would be 122 million — the number of children’s lives saved since 1990.
Melinda: Every September, the UN announces the number of children under five who died the previous year. Every year, this number breaks my heart and gives me hope. It’s tragic that so many children are dying, but every year more children live.
Bill: More children survived in 2015 than in 2014. More survived in 2014 than in 2013, and so on. If you add it all up, 122 million children under age five have been saved over the past 25 years. These are children who would have died if mortality rates had stayed where they were in 1990.
Bill calls saving children’s lives “the best deal in philanthropy”. Melinda continues:
Melinda: And if you want to know the best deal within the deal — it’s vaccines. Coverage for the basic package of childhood vaccines is now the highest it’s ever been, at 86 percent. And the gap between the richest and the poorest countries is the lowest it’s ever been. Vaccines are the biggest reason for the drop in childhood deaths.
Melinda: They’re an incredible investment. The pentavalent vaccine, which protects against five deadly infections in a single shot, now costs under a dollar.
Bill: And for every dollar spent on childhood immunizations, you get $44 in economic benefits. That includes saving the money that families lose when a child is sick and a parent can’t work.
