My understanding was always that AZ had capacity to produce many billions of doses by year (2021) end, and already had a large supply ready to go: is it possible that “first week of January” is referring specifically to the number of doses that can be administered by then which is limited by more than supply? Distribution, appointments etc. And if so, could we see the second week of January jump substantially? Access to just 500k doses would be a significant shift from the expectations that have been shared so far.
