There's a huge difference between a vaccine that's been around for decades, that's made with proteins we can accurately measure and precisely dose, and for which we have a proven track record of efficacy and safety - and whatever the latest mRNA product is.

mRNA, on the other hand, is a brand new technology, rushed to market under Operation Warpspeed as a panicked response to a biological weapon. The technology itself dates back nearly 2 decades now and has always been of dubious safety and efficacy. During its high profile debut, fake research data were used to create the illusion of efficacy that never materialized among real patients, and create the illusion of safety that also never materialized among real patients. Under this scheme, the FDA stopped being an effective guardian of the American people because it failed to adequately vet the fake data being submitted to it. It simply processed that data in good faith, as if the data were real, despite numerous high profile and very public whistleblowers telling them the data were fake.

Moreover, there are two processes to manufacture these products: one high quality, laboratory-grade, but slow and expensive, the other scaled for industrial production, but which produces countless byproducts of genetic material. All of the medical data you see published are produced from patients given drugs manufactured by the first process. It's safer and more effective. All of the real-world data you see published are produced from patients who get the industrial-grade slop they shove out the door at a tiny fraction of the cost. The manufacturers tell us the two things are identical because the label on the vial is identical. They're not.

The short answer on mRNA is that you can't control the dose, you can't control the purity (there are countless RNA and DNA byproducts in the actual injection), and thus, you cannot control the effects of the injection, either the intended ones, or the unpredictable inflammatory and other side effects from the contaminating genetic material that result as a byproduct of the sloppy ass manufacturing process they use to produce this stuff.

Get the damn measles shot. Avoid anything mRNA like it's poison.
