No that's the secondary reduction. The initial projection was 30 million by September, that became 10 million by December due to manufacturing issues, which became hundreds of thousands by end of December due to vials (with the rest not taken from the batch to the vial yet).
As for pricing you've left out the possibility that the leak was wrong. But the UK has paid to get a brand new production plant operation fully operational in the UK so that the vaccine isn't being imported which could have inflated the cost.
