The smoking gun graph: the one plot that tells the story instantly
Below is the cumulative all-cause mortality (ACM) death counts of everyone under age 80 in the Czech Republic. The cohorts are FIXED composition cohorts defined by whether or not the person was vaccinated as of 6/14/21 (the enrollment date). Source data. The cohorts are naturally matched. No scaling was done or needed.

Note:
During COVID, the unvaccinated die at a lower rate than the vaccinated. That is not a typo. The unvaccinated did better. It’s unambiguous.
After COVID is over and the booster shots are given to the vaccinated, the mortality of the vaccinated increases relative to the unvaccinated.
One graph tells all: it wasn’t safe or effective. It was an unmitigated disaster.
