The chart is not comparing one year of flu shots, it is comparing 30 years of flu shots.
There have been 3.104 billion flu shots in the US since 1990 and (according to your data) 563 million Covid shots in the US.
So, while Covid shots are roughly 15% of total flu/Covid shots they make up more than 74% of the post vax deaths.
You did not pay attention to the comment that since Covid vaccinations are new, people are monitored for 15 minutes for any side effects after receiving the vaccination. That is not done for the influenza vaccinations. Therefore, more side effects are found for the Covid vaccinations and reported. Besides you were told by the VAERS reporting site not to give direct causation to the adverse reactions. Like I heard in my sophomore statistics class: “Umbrellas in Tokyo does not mean rain in Seattle.” Use the VAERS reporting site like you are told to use it.
