It's not worth the effort when 90% of the population is trackable easier through phones/smart devices and the other 10% (which is who they'd be more concerned with) is less likely to get the vaccine, but still trackable without it in a variety of methods.
The "lol they don't need a chip you have a phone" argument is dumb, it should be "they don't need a chip, they have drones/satellites/cameras/etc".
