There are four major companies offering the COVID-19 "vaccines" (biological bioengineered agents); Pfizer, Moderna, Johnson & Johnson and AstraZeneca. Two (Pfizer and Moderna) use a technology never before approved or used "vaccine" called a messenger RNA (mRNA) biological.

The mRNA biologicals encase spike protein producing mRNA within a nanoparticle capsule–LNP [which contains nano-sized polyethylene glycol (PEG)] to protect the mRNA from enzymatic destruction by the vaccinated person's cells. This prolongs the survival of the mRNA, allowing it to continuously produce the spike protein in your body.  The latter two biologicals, from Johnson & Johnson and AstraZeneca, utilize a single vaccine technology involving the use of an altered, attenuated virus (Adeno26) to generate antibodies to the spike protein.

This man-made virus literally infects the person with a spike protein-containing virus. You should know that the spike protein is the pathological part of the COVID-19 virus. In essence, you have a man-made virus, and mRNA biological that does exactly what the COVID-19 virus does to you—it exposes you to massive amounts of spike protein. Once in the body this spike protein can enter all tissues—including the heart, the brain, the lungs, the kidneys, the eyes, and the liver.  The two main sites it invades with the spike protein are the liver and the spleen—both major immune regulating sites.

Since no studies have been done on what happens to the spike proteins once they have been injected and most important, how long the mRNA will keep producing the spike proteins, we have no idea concerning the safety of these vaccines. Moderna and Johnson & Johnson have never made a vaccine before this.
