The vaccine creates spike proteins. They wanted to neutralize the virus, so they decided that mRNA to create spike proteins via the human body would fill ACE2 receptors and not allow a real Covid-19 virus to stick.
They are turning the human body into a spike protein factory. Only after that was done; did they figure out it was the protein spikes that caused the damage, not the virus they had attached them to.
Remember Covid-19 has attached spike proteins because bat viruses just won't work on humans. Hence, Furin Cleavage Site on Covid-19.
