111 is about 4.5 days
Sounds about right cuz the lead time for my dad is about a week or 7 days cuz that is when the event is happening for them pop up sites.
However, we got people who goes into a clinic around closing time and hoping that there are left overs. I think the maderna comes in a pack of 8 so once you open up a new pack, you gotta shoot it all. Some places even goes outside and find random people just to shoot it all without wasting.
