Horribly shortsighted and stupid. Driving with your eyes shut is unsafe, not keeping them open to detect and respond to the hazards ahead. I can't scream BS loud enough.
In 2019, NIAID proposed an ambitious scientific network focused on pandemic preparedness, research, and response - the "CREID Network".
Ten centers kicked off just as the pandemic was taking off, playing critical roles throughout.
We were just notified the whole network is terminated.
Reason? 👇
