The thing about using person- years is that unvaxxed fully vaxxed are in this status for long periods, while most of partially vaxxed are in this category for only around 6 weeks. So even if the mortality rate is higher, the absolute numbers are lower. Comparing unvaxxed vs fully vaxxed (>21 days) then mortality rate is lower for fully vaxxed. Of course, what happens after 6 months is the key.
