The rules do not exist to manage risk. They exist to strike a balance between ethics and risk in emergency situations. If you’d like to change them going forward, feel free to advocate. I think it’s best we stick with our current rules this round.
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.
Imposing political pressure on experts and forcing them to approve against their judgment would be a horrible corruption of these regulator institutions.
Maybe the expert regulator think that the bar should be lowered. But then they should come forward. This should not be ordered by politicians or their handlers.
