That would also be an extension of "wanting someone to take care of them when they're older" I'd think. If you're poor and can't afford good medical care, for yourself when you're old, plus your kids in their youth, you'd want kids who could take care of you personally, and enough to ensure they live to do it.
His problem is thinking that countries and/or people getting richer will improve health because now they can "afford" vaccines, and that this will decrease how many kids people have. I agree that the solution is, as you say, to bring people out of poverty. Useless injections not required.
