Here is the thing the mRNA vaxxes are the 3rd line of defense against illness. (*see blow for explanation) The "Vax" which was only defined as a vaccination within the last month because it was not one, only increases white blood cells which are there to fight off an infection AFTER you have it. (may/probably decreases 2nd tier responses to all other infections including covid) It does not help prevent you from getting it like a normal vax. You may not get sick, but you will still spread it and have the same viral load as an unvaxxed with fewer or no symptoms.

I will stick with my own immune system and not tamper with it. Also the vax decreases your body's ability to repair it's DNA. (FACT TAKEN FROM National Library of Medicine) "Mechanistically, we found that the spike protein localizes in the nucleus and inhibits DNA damage repair by impeding key DNA repair protein BRCA1 and 53BP1 recruitment to the damage site."

First line of defense is our skin and mucus membranes. Viruses cannot just migrate through our skin and are caught in mucosal "traps" before infection can occur.
Second line is our innate non-specific immune defense. This is a rapid local response to viral/bacterial invaders at the immediate point of contact. Macrophages and neutrophils, interferon (anti microbial proteins created by our own body), and even fever.
