It's just a crude measurement comparing infection rates between vaxxed and unvaxxed in the relative age groups. It's what Pfizer uses, so that's why they chose that method, to compare apples and apples. So what they are looking at is the increase in vaxxed case rate over time compared to unvaxxed and measuring the change. It demonstrates that over time, the case rates for vaxxed continue to rise and have now surpassed the unvaxxed case rate for all age groups >30 and continue to increase.
