Microchips

Even if vaccines have microchips which allow the government to track us(which is a completely absurd claim, probably made by a bunch of high school drop-outs for some extra money), it won't change anything. The government can use anything that has a location sensor(I.E. your smartwatch, your phone, your GPS) to track you, they simply choose not to. A Karen may argue that not everybody has their phones n them, but who's complaining about the microchips? Karens! And who has a phone on them all the time? Karens! 

Either way, the government knowing your location doesn't change anything. I, for one, would love the government to track everyone(myself included), if they chose to use that data to fight crime, for example. The government is already tracking the phone, for example, of a criminal/suspect that has escaped from a crime scene. Tracking everyone is just a preventative measure to ensure the safety of everyone(except criminals)
