Throwing stats about like this is ludicrous, they can be selected and spun to fit any narrative you like. It's all about clicks.
Same figures from uk today, being spun against the vax hesitant under 50s includes the fact that 70% of over 50's who died from (with) Delta were vaccinated. Then you have to understand the sample size, the period over which the data is collected. Which vaccine, when, who. Most of the people going to these gigs will be in that demographic, if you think you're 100% safe, think again.
If everyone is vaccinated, 100% of deaths will be vaccinated.
