Um... being vacinnated is not lowering the possibility that this person will share covid to another person. What it does it lowering drastically the possibility that this vaccinated person might be hospitalized or will be sick at all. Every vaccine does this but none from what I know stops spreading the virus / helps in 100% to not get sick.
In this case I don’t understand why you expect stuff to be vaccinated - it‘s their own decision and every government forcing someone to do this is fool.
Disinfection in UV rays for 15 minutes or alcohol 60%+ is enough to help to not carry it from service background ( I mean place where they did the stuff). But as airborne virus, covid spreads mostly by air so masks they wear for sure helps more and you don’t have to worry
