I haven't got a clue. My arthritis requires me to take an immunosuppresent, but it's quite a mild effect on the immune system. I wasn't shielded or at high risk, and my medication alone doesn't increase my risk but I also take drugs for hypertension. Apparently that combination increases my risk, but not by much. "Medium or heightened" something like that according to the rheumatologist.
I doubt the system has the nuance in it for me. So probably be August - September, which might be about right anyway. I'm fit and relatively young.
If they manage a million a week then fair play. Let's see.
