I think all states should have two weeks on hand at all times so people are fairly guaranteed to get their second shot. I’d have to work out the math, but it’s not up at 90%. I was a buyer, and although shipments are usually on time and regular, they do get screwed up. We have a snowstorm right now in the northeast, it wouldn’t surprise me if there will be a delay in shipments. What if something happens at the manufacturing plant? Always good to have some cushion. The delay is only initially, and then there is a constant flow of goods and vaccines with the extra stock of product always there. The way I see it, if they see shipments are held up, they cancel first doses for a few days to preserve the back stock for second doses, keeping in mind that these vaccines do expire so that must be monitored too. A way to avoid cancelling appointments, which causes a headache and ripple effect, is to not schedule more than 7 days out.
