2) Sterilizing immunity is a pointless distraction. Seatbelts don't provide 100% protection in a car crash, surgeons washing their hands doesn't prevent 100% of infection, and having smoke alarms and two points of egress in a bedroom will not 100% save your life during a disaster. In fact, I can't even think of a mandated public safety feature that is 100% effective.
