So, all governments officially said all of those while knowing them to be untrue? That's a bold claim ( i live in France and don't recall anything of the like on any of them). Care to share some sources?

The French government did.

I can also add the lie about 90% of patients in ICU being non-vaxed. We were later told that it was a misinterpretation of the available data.

Etc etc. It became kind of a meme: when Olivier Veran says something will never be done, it ends up done quite soon. I was about to get this vaccine. But those blatant lies deterred me from doing so.

It's not lying to change one's opinion, or to be mistaken. Lying needs intent. Véran changing his opinion or being overruled by Macron doesn't mean any one of them is lying on purpose for some nebulous purpose.
