Excess mortality is a great measure but I don’t think the authors adequately show their methodology accounts for confounding variables. Not taking into account clinical characteristics (yes, I know it is difficult to link data in the US) is a major limitation. Figure 1 also reports a correlation of 0.97, but visually it does not look close to that. The bottom left is clustered with data points and the top right is pulling the correlation towards 1, so the methodology may also have limitations. I was surprised the authors did not address this.
Regardless, it still explores excess mortality and vaccination status, which is quite interesting

Reply to A study in the US has found, compared to unvaccinated people, protection from the risk of dying from COVID during the six-month omicron wave for folks who had two doses of an mRNA vaccine was 42% for 40- to 59-year-olds; 27% for 60- to 79-year-olds; and 46% for people 80 and older. by Wagamaga
