When we have a quarter of all children not getting vaccinated for basic diseases, we have a huge health problem and an easy way to address it. Vaccination is the best example I know of that shows how important and effective international aid for health can be. At a tiny cost, we can prevent millions of childhood deaths every year. And there is plenty of experience to show that countries are pretty good at carrying out successful immunization programs. This is not a speculative or risky investment.

And the benefits are huge. Not only are there the obvious health benefits — both for children and for the broader community in the longer run — but there are large economic benefits for countries, and these have been only minimally recognized to date. Basically, healthy populations make it easier to have healthy, growing economies, and to reduce poverty.

Is there waste in foreign aid? Yes, of course, and we need to do much better with what we give. But programs in clean water supply, sanitation, and family planning have been enormously effective. As Americans, we should support such aid because, first, we really do care, and this is a good way to make a difference, and second, because a healthy world will be a more productive and safer world.
