The claim is that the definition was changed specifically for the COVID vaccines. This is wrong, since other vaccines also weren’t covered by the old definition.

There’s also a serious problem with the phrase “the definition.” There are many definitions. There isn’t a single authority which decides what a word means.

“It was the first time something didn't work that way and was additionally being mandated.”

Come on, seriously? The tetanus vaccine is required for school in many places. Why are you saying something so obviously incorrect, and with an example that disproves it already being part of the conversation? You accuse me of not accepting debate and you do this kind of thing? I can’t even.
