That doesn't do anything to prove your statement that "vaccine risk/reward isn't there for those under 50 years old who don't have health challenges".
For your statement to be correct, you'd need to demonstrate that more than 5 out of every 1,000 vaccinated people die from the Covid vaccine. Good luck backing that up.
I've read that 3.4 Billion people across the world have received a covid vaccination (6 Billion vaccinations administered in total). In your view, do you believe that 17 million people have died from the vaccine?
