Wait, wait!

Let me get this right, because I am sure a few people in this thread are as baffled by your comment as me. Are you saying that because there is a vaccine there will be no need for a breathalyser to detect covid as people are vaccinated?

A few points for you to consider here:
1. The vaccine is not mandatory.
2. You are still susceptible to the virus even with the vaccine, just less susceptible as with the standard flu vaccine, it doesn't mean you won't catch it, it means you will generally have lesser symptoms.
3. Those that are vaccinated can still pass on the virus.
4. This is a virus that is here to stay for the foreseeable future, some have mentioned years.
5. If you are aware of what Nanose is doing you would be aware that the device isn't just for covid. I'll let you DYOR rather than elaborating for the people here that already know its capabilities.
6. The accessibility and speed of the test results will be game changing, possibly leading to borders opening sooner than expected.

The only failure I see in your comment is your failure to research.
