1. RNA vaccine ingredients. These vaccines have RNA wrapped up inside tiny droplets of oil and cholesterol. The lipids are similar to your cells - they have mild chemical charge on one side that orients the RNA (short-lived genetic message encoding the coronavirus spike protein)
2. ... inside them (biological systems do this all the time). There is also polyethalene glycol - this is a common compounds used in medicines to make them more water soluble, it’s also used as a constipation medicine when given at high doses and in a bunch of other applications.
3. No, the vaccine doesn’t have any formalin or stem cells or “green monkey cells” (I actually don’t know what that is - got it in a question this morning), or carcinogens in it. It’s droplets of oil that protect the RNA until your cells take it up & process the RNA instructions
4. The RNA cannot incorporate into your genome so it’s not genome editing - it degrades after a few days like all other RNA. That’s why you need a second booster shot four weeks later. https://www.americanpharmaceuticalreview.com/Featured-Articles/364236-Recent-Advances-in-Lipid-Nanoparticle-Mediated-mRNA-Therapy/
