I think Gov should buy the vaccine and provide it for free. Private companies should rightfully charge a premium to the governments as they took: 1) Enormous risk 2) Expediency 3) Investment of talent 4) Demand is through the roof; all this even if the governments were involved in hedging the risk for spinning up manufacturing lines.
In the US that is what is happening - no one is paying for the vaccine.
It is intellectually vapid to get worked about the fact companies are making a $15 marginal unit profit on a vaccine that has 10x the utility of the average annual physical but costs 1/10th as much.
