Your analysis is good but they cannot hang a flawed vax around Trump’s neck without admitting the vax is flawed and they are not ready to give it up. When it’s time they will memory hole the fact they pushed it.
You’re right. Blaming Trump will backfire on them.
With the SwampVax deservedly hanging around Trump's neck, perhaps the Left will claim more of a need for masks, distance and drop boxes.
I do agree, though, that the Swamp will continue to advocate for new and improved versions of what essentially are Windows updates for people. Unless confronted and destroyed, the forces Trump previously aided will continue funding malware under the table and selling anti-malware via their bullhorn of fear.
That memory hole will be big as the sun the day they roll it out and start jamming everything but the kitchen sink into it.
I agree with Renz. They will throw Big Pharma under the bus if they conclude that that is wnat’s needed protect themselves from Trump getting the Republican POTUS nomination, or from Trump winning the 2024 general election for POTUS.
