I will try to be polite, as your deep level of ignorance of virology and molecular biology is frankly embarrassing.
When you get a coronavirus infection, virus particles covered in thousands of spike proteins each enter your body. In the case of Covid, trillions of spike protein covered viruses literally distribute all over your body. What this means is that if spike protein is a carcinogen as you seem to believe, anyone who catches Covid or even a common cold caused by a coronavirus is doomed. The small quantity of spike protein produced in your arm in response to the mRNA vaccination is nothing next to the huge quantity of spike protein produced all over your body during a coronavirus infection. Yes, vast quantities of spike protein are made by your own body during infection, because viruses use your body to make new viruses.
I do not know if it is even worth my time to try to explain what mRNA, DNA, or the SV40 promoter are. It's probably not worth my time to explain how an antibody response occurs or what the roles of IgM, IgG, IgE, IgD, and IgA are. You appear to be just repeating words that you saw in antivax propaganda, words that you have no idea what they actually mean and seem incapable of truly understanding.
My advice to you is to stop being so prone to fear just because some scammers throw words around that you don't understand.
I am not an idiot. I can hit a coke can at 500 miles. If you think I am in awe of your magnificent intellect,then you’re mistaken. Your oversimplified response shows your attempt to bluff people off the facts. Piss off. The mRNA was thought to degrade quickly but it did not. It’s been published many times and it’s still there 180+ days. Free spike is not from viral origins - it’s from the vax. Any cell doing so will be attacked by the immune system until exhausted. The bio distribution was not well understood until after the fact. They didn’t test for many specific cases (example pregnancy or breastfeeding) yet they were MANDATED TO TAKE IT. Those are all facts. Piss off. I now know you’re not an ex-Dem, typical Dem thinking you’re superior to those around because you just think so.
