Why is the mRNA vaccine more expensive than the "classic" vaccines?

My understanding of the process was, that not only the mRNA vaccines are faster to develop, but also easier to scale up in the production. But the prices are between ~20 and ~40 for the mRNA and the AstraZeneca around 4. Why is that so?

Is it only because the production process is new and the factories have to create new production lines for it?

New production lines, paying for R&D, the storage requires colder, more expensive to buy and operate freezers, and therefore more expensive shipping too. 

There's also a level of risk present that many other vaccines don't necessarily face that could also factor into pricing.
