Let's assume there is causality. So what? I have the impression people are just bow realizing that every drug comes with a piece of paper, that includes all known, and in a lot of cases potentially deadly, side effects. But nobody stops taking Asperin, paracetamol and other things.
All that was achieved by extensive media coverage of AZ was, that authorities and doctors are kind of obliged to announce every issue with it. And that these issues are just plain overblown. And again hyped by media.
