Long time ago I spent a lot of time with a girl that had Polio as a child.
She had not been vaccinated.
The Polio vaccination was fully tested before it was allowed onto the market.
This deadly SAES-CoV-2 shot was ILLEGALLY granted a EUA, when "safe" medications were available, and this shot was not fully tested for safety or proven to work.
Those effective treatments were way too inexpensive.
