So back on topic....
I empathise with Deleted User, but alas the show must go on. It is because of GC's and Aramis's positions that govt needs to press on and open the borders irrespective of vaxx numbers (after a sufficient notice period).
e.g. If it's theoretically possibly to reach X% of those in high risk categories by 1st May, then that should be the date.
GC (and plenty of others with much less bonafide reasons) will simply wait until the covid risk is present enough otherwise.
Waiting is a luxury that society should not be prepared to pay for.
Time and tide waits for no man.
