Pfizer actually manufactures only half of the third step in the process it acquired when it bought BioNTech. Everything before is actually made by only three subcontractors of BioNTech in 3 factories in Switzerland, Germany and Belgium (which does the other half of the step). They are already working at well over originally planned maximum capacity for these plants. And that's for the original 2 doses only. Pfizer is supposed to have manufacturing capacity open sometimes later this year... Where they are gonna manufacture the booster ? Good question. So yeah, you can say it's not gonna be that fast.
