They took what was the equivalent of a plastic/fake virus body and stuck the spike protein on it, gave it to animals, and the animals got very sick/died. Conclusion being that the spike protein IS the part of covid we want to attack with a vaccine.
Both Modern a and Pfizer used every single epitome on the spike protein, the whole enchilada, in their mrna recipe.
So ok, maybe people with covid made antibodies to other parts of the virus, maybe an epitome on its bottom or something. But is it relevant, or iow is it pathogenic?
The whole premise is that antibodies to only the spike protein make covid vaccines leaky.
So for instance with Hep B, they took the main antigen, the one we use for testing in fact, and created a vaccine from it. But then they found people still had the disease, while testing neg for the antigen. So obviously more of the virus than that *one* antigen causes disease. In the case of covid vaccines, however, the spike protein contains many antigens, and we vaxxed are indeed making poly clonal abs.
Way back in the 1980s I got the vaccine series. And OMG I was mouthpipetting racks and racks of greenish-sera hep samples for testing. I never got Hep B.
It takes more than the spike protein to make the virus. The rest of it is not just fluff along for the ride. Now that we know Delta evades the vaccine why isn't it being updated for Delta? After all, the flu vaccine is formulated against multiple strains every year
The whole premise is that antibodies to only the spike protein make covid vaccines leaky.
That the vaccine is leaky is not a premise, it is an observed fact. You folks seem to have a lot of trouble telling the two apart, meaning you are approaching the whole question from a political rather than a scientific angle.
That's the problem right there: people looking for an easy way out, mucking around things they don't really understand and thinking they are geniuses when it doesn't immediately blow up in their faces.
When you go all wooly with what should be hard science and your standard of success is that everything seems ok you invite disaster. They are like a bunch of teenage boys setting fire to an ant bed using gasoline and thinking they are mighty as they watch the ants fry. Not realizing the ants aren't what they should be concerned about.
