Let's guess here, the signal from the vax is a bar code that identifies the vax taken and is linked to your social credit score. Get all your boosters or lose all your rights.
Police will be authorized to use deadly force against unvaxies that refuse "vaccination". The scanners will link to an FBI/CIA database that scrapes the web so that, even if you took the vax, any wrongspeak or wrongthink results in termination.
"Did you question the 2020 election? I know you say to took the latest vax, but the scanner here says you haven't and you're resisting. No hard feelings, just doing my job." BANG
If it comes to this, when they ask about my vax status I will simply reply "wanna trade shots?" They will be like "huh?"
Hey, I've got a hot booster shot for you too!
Yeah, its +p+
This is fake
