Even if it fit all those criteria for being an alternative it's not like it's some kind of thing that couldn't be amended if they really needed/wanted to. saddens me how reactionary everyone is.
Edit: also I forgot to make the point in my replay above... it's not like having three vaccines under is preventing another vaccine from getting EUA so even under this logic framework it is nonsense. are they hinging it on the fact that it's an approved drug for some other disease?
