Pfizer vaccine got fully approved August 23,2021..and according to Bob Woodward 's interview, those in the know,knew the dangers and were working on the vaccine at that time..so the @2 year timeline was pretty accurate..2-5 years is still fast by established standards..most vaccines over 10years before the use of new technologies and techniqueThere is some really good reading material in this thread back a few hundred pages ago. When it was operation warp speed some were saying vax should not have been the priority and treatements should. That was also back when a few of the more frequent posters here said the vax would take 2 years to 5. Almost like magic the opinions changed. Weird / Strange ? Xfiles type stuff.
