As the weekly stats were surprisingly absent from the Vaccination Status data, I figured it might be fun to take a look at how the different cohorts did, Deaths-wise, for 2023.
tl;dr: Boosted not faring well. In fact, worst of all, even per-capita.
As usual, all stats come from the Te Whatu Ora weekly updates.
NZ Cumulative Deaths “with Covid” by Vaccination Status – April 2022 – December 2023


NZ Monthly new Deaths “with Covid” by Vaccination Status – April 2022 – December 2023

Now, with the age-stratified Vaccine Rollout obtained via OIA, we can at least (because the others were never provided age AND dose stratified) do the stratification for the Deaths With Covid table. It’s somewhat interesting.
The 80+ 2-dose cohort was worst, then their Boosted, but their Not Fully Vaccinated group was a lot lower. I wonder if that was during that period where all those 80+ people who finally got dose 2 died within 29 days of the dose.
Next came the 65-79 2-dose cohort, their Not Fully Vaccinated next, then their Boosted. 65-79 is the only cohort that had Boosted fare best.
0-64 cohort saw a significantly smaller “with Covid” mortality rate. Their Boosted cohort was worst, then their NFV, then their Fully Vaccinated.
Now, of course, this is deaths (of any cause) where the person had tested positive for Covid within 4 weeks of death. When you’re getting vaccinated against a disease, I don’t think it’s overly useful when the people who take more than 3 doses of it die within 28 days of catching it.
The argument in favour of getting Boosted is weak, in my opinion.
