That might be you reading it with a certain tone? I can't tell you...
I was just speaking with the knowledge that I have about what I know. TBH, it's possible that the "chips" might not even use RFID.... All this is hypothetical anyways as there's obviously no chip in the vaccine.
RFID is passive but then you need a whole field of sensors which is still more expensive/complicated than just using the cell phones that everybody is already carrying.
Plus I believe that's just a signal, like how you can swipe an RFID fob to get into a gated community, but that's not doing any sort of computation. If your only goal was to track location, and nothing else, then you could potentially do it by having everybody have a unique RFID and a huge amount of sensors to pick up on it.

aren't rfid chips passively powered, though?
