Apparently, if you've been infected, 180 days from the infection on a rolling
one month basis. You needn't ask how I know ;-)
I'm not sure when the time runs out for the vaccinated. It does seem to go on
indefinitely for the double jabbed, although logic would suggest that there
must be an end date.
