Covid 19 vaccines are not got trackers in them ?

I feel like if there were any sort of tracking in them they would all have to be centralized. (instead there are multiple manufacturers all over the globe)

it also probably would have a higher effective rate so there wouldn't be so many people questioning it.

That's not to say I don't have my reservations.

Dan Brown's Inferno or Utopia on Amazon Prime (both are fantastic!) don't help any.
