"Now, a major new study shows that the virus spike proteins (which behave very differently than those safely encoded by vaccines) also play a key role in the disease itself."
Remember, the mRNA in the vaccines create a protein which happens to mimic a part of the structure of the virus spike proteins. It does not create an actual COVID-19 spike protein.
The strategy is akin to training a search dog with something that looks like a bomb, and smells like a bomb to the dog, but isn't actually a bomb.
There have been no long term studies comparing the effect of natural spike proteins to the artificial versions.
Remember Pfizer told the FDA that the artificial spike proteins were not expected to travel from the injection site.
