I see North Korea is accused of trying to hack Pfizer servers to get vaccine information. Totally unnecessary, since they are getting a few million of AstraZeneca's doses. Not to mention AZ's non-profit approach is setting up manufacturing in multiple countries around the world: Basically in any country that could actually produce the vaccine.

I bet AZ would give them easy-to-follow instructions and starter cultures for free, if they just asked nicely. If they can ferment kimchee, I bet they could grow the needed adenovirus.
