The California Department of Public Health supplied a nonsensical answer when asked to explain the rise in the California COVID case fatality rate (CFR) after the COVID shots rolled out.
Supervisor Sue Frost (Sacramento), the only red pilled Board of Supervisors member in the US (as far as I know), asked the question of her county health officer as to why the CFR went the wrong way after the shots rolled out (it went up instead of down).
The county health officer didn't know so she had the California Department of Public Health (CDPH) respond directly.
The Fatality Ratio graph from the CDPH that you provided in your previous response shows that the Fatality Ratio reversed direction (went up) instantly after the COVID shots were introduced, and then remained flat for nearly a year until Omicron. If the COVID vaccine worked, wouldn't you have expected the Fatality Ratio to go down over time as more people were vaccinated rather than remain flat? The variant didn't change until later in 2021! And why would it go up right after vaccination? Was it predicted it would go up and then remain flat?
COVID-19 vaccines first became available in the middle of a surge in COVID-19 disease in late 2020 and early 2021. The risk of death increased during the surge for those who were not yet vaccinated. Meanwhile, it took several months after COVID-19 vaccines first became available for many long-term care residents to be vaccinated against COVID-19.
The Fatality Ratio of residents in facilities included a mixture of unimmunized individuals and immunized individuals. Comparing the mortality between unvaccinated versus vaccinated residents would better indicate the protective effect of vaccination.
More rigorous evidence of the effectiveness of COVID-19 vaccine in protecting residents of long-term care facilities against severe COVID-19 infection and death includes, but is not limited to, the studies linked at:
If you have a FIXED known group of people and you give 98% a vaccine that is supposed to reduce their COVID mortality by 50%, the mortality should go down.
It doesn't get any more complicated than that.
No fancy math required. No Cox regression analysis needed. All raw data.
