I don't understand your comment. The phase III study was done I'm the real world, not a lab. So it's not surprising we are seeing the same numbers as it rolls out. I'm fact, it would be suprising if it didn't match the studies.
They don't just select from the population at random from these studies. For example the study excludes those over the age of 85 or those that are immunocompormised. You can see more details on the exclusion criteria listed in seciton 5.2 of the Pfizer study: https://pfe-pfizercom-d8-prod.s3.amazonaws.com/2020-09/C4591...
