CDC changes definition of vaccine

It intriguing how the CDC changed their definition of terms in the last week or so from:

“Vaccine: A product that stimulates a person’s immune system to produce immunity to a specific disease, protecting the person from that disease” (per the wayback machine) to

“Vaccine: A preparation that is used to stimulate the body’s immune response against diseases.” (per the web site earlier today).

I am really curious about the timing of why at this specific time, did the CDC decide that the definition of vaccine needed to be changed.
To me it says: they are seeing more trouble with the vaccines than they are saying publicly and don’t want to be held to the old definition of what a vaccine is vs a therapeutic. It doesn’t matter from a usage standpoint, but it does from an accountability standpoint.
