Hypothetical - lets say they invent a vaccine that works for a limited time - limited immunity - just like it seems to happen to people who were infected. The immunity wears off.

So you take an antibody test and find you don't have antibodies, so you get a vaccine. Great. You're immune, but depending on everything that makes you you, the vaccine antibodies may last a short or a long time. So you need to get monthly antibody tests to see if you still have antibodies or you may need a vaccine booster shot.

Theoretically, each test recorded on QDX HealthID should generate some income for the QMC subsidiary.
