> I personally doubt they'd still be spending that money if they needed it, there's been plenty of time for a stability analysis by now.

I don't believe your logic follows. There's a lot riding on this vaccine working as advertised, thus there is considerable pressure on Pfizer/BioNTech to deliver on that promise. If they know their vaccine is at peak effectiveness when transported at -90ºC and that the effectiveness drops if handled at lower temperatures, and if time is critical as it is, then they have all the reasons in the world to just play it safe by going with the costly but reliable option.

That's true, on the other hand, consider that Moderna has lowered storage requirements twice in the past four months. This gives us three options, Is it Moderna taking more risks, Pfizer being more risk-averse or is the Moderna one inherently more stable?

Moderna's vaccine was the second to enter the US market. If Pfizer/BioNTech delayed their vaccine to work on lowering the temperature requirements, Moderna would eat their lunch, and Pfizer/BioNTech would be relegated to second place on the place it matters the most: the history books.

As is, I'm sure that Pfizer/BioNTech are already working on improving temperature requirements, while leading the race.

I have zero insight on the situation, thus I can't really tell. However, it's clear that each and every single actor in the story, from biotech companies to politicians and also regulatory bodies, is taking way more risks on this issue than what they would otherwise take.
