I very much hope NIH and CDC can help walk some of this back. It goes to naked self interest outcomes: The US has massive exposure of risk.
It used to be the primary problem here was womens reproductive health. I am unsure that has anything to do with this, but perhaps the Trump goal here is to satisfy his god-bothering base, as well as "win one over" an agency he doesn't like.
As a non-american I am amazed that deliberately disclaiming control over an agency like this is held to be in US interests. Its so isolationist, it begs questions about how seriously NATO has things covered. Or AUKUS.
You would not want to bet on any current financial commitment being worth the paper it's written on.
