There is a BIG difference between getting the little covid spikes from having covid, which go away, to having the covid vaxx direct your cells to manufacture the spikes. The cells will manufacture the spikes till they are dead and replaced.
Among others, my bone and nerve cells are producing the spikes, which means I am facing years of spike production.
The Pfizer and Moderna vaccines work by introducing mRNA (messenger RNA) into your muscle cells. The cells make copies of the spike protein and the mRNA is quickly degraded (within a few days). The cell breaks the mRNA up into small harmless pieces. mRNA is very fragile; that's one reason why mRNA vaccines must be so carefully preserved at very low temperatures.
How long do spike proteins last in the body?
The Infectious Disease Society of America (IDSA) estimates that the spike proteins that were generated by COVID-19 vaccines last up to a few weeks, like other proteins made by the body. The immune system quickly identifies, attacks and destroys the spike proteins because it recognizes them as not part of you. This "learning the enemy" process is how the immune system figures out how to defeat the real coronavirus. It remembers what it saw and when you are exposed to coronavirus in the future it can rapidly mount an effective immune response. The Novavax vaccine introduces the actual protein into your body to produce an immune response similar to many other vaccines currently in use.
