At least your link had an embedded link inside of it that had some breakthrough data, but not enough context to verify the results for the entire period of time. In the recent month, and it would appear to be about 85% of deaths. At the beginning of August, it was only 70% of deaths.
The West Virginia Dashboard, which Buff could have provided, had he understood what he was even arguing about, could have got him somewhere in recent months when there were a high number of vaccinated individuals.
However, in some of these statistics, the start counting unvaccinated deaths starting December 14th, 2020. By April of 2020, only about 25% of people were vaccinated. There overall statistic is around 6% of deaths were vaccinated, but it is skewed by the lack of vaccinations how they are picking their start date.
I crunched some numbers based upon the embedded link provided for the Covid dashboard of WV.
August 2021- 80.6% unvaccinated deaths
September 2021 - 85.56% unvaccinated deaths
Further, of the unvaccinated deaths counted from 12/14/2020, approximately 85% of the deaths were over 60.
This pandemic of the unvaccinated showing young people is a farce.
It goes back to what I have said more than once, do a cost/benefit analysis of the vaccine. If you are older, the benefits might outweigh any potential risk. But for the young, especially under 40, I do not believe that is so.
