So, seatbelts don't work., right?
Ok, so it does work but it doesn't stop you getting it or transmitting it. 90% have taken it. Question then: Why are there still restrictions, major restrictions, on travel, employment, venues, borders. Its a flop, it is ineffective, we need boosters and there is no end in sight.
Great product! We bin sold a pup. It clearly doesn't work very well at all, the evidence is everywhere for all with eyes to see. I say it is ineffective then. I made a mistake, it works but it doesn't.
As for your seatbelts, baaa, a sheep's comparison. Can't you come up with something better than that? By your reckoning, we can put a seat belt on but we still can't drive. Awesome!
