The shortage caught many Americans by surprise, but it followed decades of warnings from health experts who said the nation's system for vaccine supply and distribution was growing increasingly fragile.
Governments are responsible for vaccine programs. This is a failure of government. Certainly a failure of the Bush regime, but it's older than that. I suspect it's a failure of congress rather than the executive branch -- which makes it a classic failure of Republican governance.
It resembles the same failure in governance that led to the fragility of our electrical infrastructure.
Republicans don't do infrastructure.
