One big reason the Covid vaccines failed was the antigen changed.
Not that I’m a virologist but saw an article be one scientist who predicted this.
The article stated coronaviruses mutate quickly.
Then I looked up the childhood vaccine schedule and not one vaccine to a coronavirus was there.
mRNA vaccines might work someday, but then again we were promised gene therapy in 1990 and it’s still not here.
Coronaviruses in general mutate quickly.
Nobody had ever created a successful one-shot vaccine for a coronavirus before.
So it was something between a fool’s mission, and a lie, to sell the mRNA clot shots as “safe and effective”.
OK, it was a baldfaced lie, since the Pharma companies lied about multiple aspects of the safety profile of the clot shots in their hurried, incomplete, rushed through testing.
The antigen changed but the secreting spike protein was attached to different cell types that don’t change like cardiac, neurological, muscle, brain, bone marrow cell precursors and other tissues that incorporate the cell.
Your body sees the spike protein as foreign AND the attached cell as well and attack them in a small percentage... however the small percentage are basically having a host versus graft reaction with the body’s modified spike protein tissues under attack.
That’s why this isn’t a “normal” vaccine but gene therapy that is now re-defined as a “vaccine” in order to get the EAU and the qualified corporate immunity.
