You call out a lot of unfortunate communication missteps. What are you referring to though with redefining the word vaccine?

That is one hell of a euphemism for being caught out in a lie. Fauci admitted to Congress that he intentionally lied to the public about the effectiveness of masks in order to manage people's behavior. Of course he tried to make his admission as confusing and unquotable as possible, which might be why you aren't aware of it: "...there was a paucity of equipment..."
I get the whole excuse about employing deceit in the furtherance of some greater good... but the problem with that kind of policy is that it can only possibly be used once - and after that you are left no other tools, because you can't be trusted. Do I think that was the motivation for most of this? Sure, why not... but I also know that it is a very convenient way to dodge responsibility for expanding federal power beyond what many imagined even possible while also funneling a huge amount of money. There is a reason why the mega-wealthy are coming out of this economic catastrophe with so much more than they had going in.
Before: "Vaccine: A product that stimulates a person’s immune system to produce immunity to a specific disease, protecting the person from that disease. Vaccines are usually administered through needle injections, but can also be administered by mouth or sprayed into the nose."
After: "Vaccine: A preparation that is used to stimulate the body’s immune response against diseases. Vaccines are usually administered through needle injections, but some can be administered by mouth or sprayed into the nose."

But what is immunity, other than an immune response to the disease?
