Time's short and they're counting on obscurity: please let German politicians know how horrifying their reversal would be.

Dismantling the Institutional Review Board (IRB), that oversees all human subjects research, is bad. Really bad.
The entire HR department at the CDC is gone. Everyone at the IRB, which makes sure studies are conducted ethically and rigorously, and the ethics office, which oversee conflicts of interest for CDC leaders and advisory committee members, were also let go.
