The date on the calculator continues to fall slightly (moved 3 days closer in the last week into March for me) obviously it's only an indication however whoever has set the parameters doesn't see any issues with supply.
Vaccine Queue Calculator for England
The vaccine queue calculator for England estimates where you are in the queue to get your COVID vaccine based on your age, health, and job.www.omnicalculator.com
Presumably it takes an average of vaccinations over the last week (or similar) and uses that to predict how far it takes. A very simple model.
I don't think they would know about any potential shortages, and probably wouldn't know how to build that factor into it.
