> I'll update that to "The CDC doesn't recommend it", in that case.

As a native speaker, even that language feels as though the CDC discourages vaccination despite the literal meaning not implying that. This is a case where it's probably best to be more verbose and explain in full details.

I don't know why the CDC themselves choose to use this language. It's confusing.

Agreed. I’d rather see “doesn’t actively recommend” or “is neutral” or something.

There's a reason I cited the entire paragraph, yes.
