The FDA has a process in place as per the Pandemic and All-Hazards Preparedness Reauthorization Act of 2013. If you find that legislation inadequate in some way, I think following due process to change it is the way to go. If how we handle pandemics should be more agile, let’s get legislation behind that.
I don’t think jerking our knees over an ethics safeguard that led to a pause in administration of a vaccine that soon won’t be widely available anyway is a great habit to get into.
