What if the vaccine immune response is only 60 or

What if the vaccine immune response is only 60 or 120 days? We would have to be continually testing forever. Would people support such an inconvenience? The small companies won't spend the money but I'm pretty sure large companies would require it for employment from the fact most senior management are older and more susceptible. Companies have a fairly large investment in their management and training so they aren't to keen on the idea of losing their investment.
It's going to be very interesting watching this play out. Speaking of wanting more, as a side note, I think it would be beneficial if people that move a lot could roll personal medical records into the QDX HealthID program too.
