No one should have to tell you. Go get the Excess Deaths data and observe with a GASP that there are none age 0-44. None.
People age 0-44ish have died at a given rate pre 2020. Since then, even during the virus surges, the death rate remained multi year normal (adjusted of course for population gain).
Google Excess Deaths ALL CAUSES. It’s right there. Nobody has to tell you anything. Do your own research.
More precisely, death count. Rate derived therefrom.
My wife is being checked for a brain virus causing brain cancer that was from simian monkeys back in the 50’s who were the source of polio vaccine. The monkey had a virus with a 50 year incubation. Sounds unbelievable. I also think about Thalidomide for morning sickness for pregnant women. That was the 1950. There are people, still living, without arms or legs from it. Science needs to go slow.
