I think the concerns are very valid about AZ and German's have a right to choose. Big point is that HN is largely an American forum so there will be a bias against AZ doubters.

Interesting that Twitter and Facebook also not labeling the concerns about AZ as "Fake News" so likely there is some merit to the claims against AZ.

I am also against taking AZ as well. If HN folks are confident it is fine go ahead. I will choose what I'm comfortable with and Germans or anybody else for that matter should have a say.
