Maybe, maybe not. AZ is unique in not using a "stabilized" spike protein (one edited not to become un-capped after cells produce it) and resembles Janssen (J&J) in screwing up the "signal" by throwing in chimp adenovirus proteins. Since there's no real-world proof that stabilizing worked in any of the other vaccines, and there's no region that represents a "Janssen wave" there's no easy comparison to be made between AZ and the other platforms without throwing a billion assumptions of relative exposure rates around.

For a sign the UK (and therefor AZ) might not actually be unique, see the rates in the Northeastern US, especially New York. These places all had spring waves, and no summer waves. Now it looks like their "autumn waves" might be starting to plateau.
