Actually, only from what I’ve read, as we know mRNA has been around for quite awhile. Originally it was being looked at for Cancer treatments, and HIV. And still is.
It’s truly a break through.
I got the Moderna and, except for the new eye that I am growing on my shoulder, I am doing well.
Read up on Derek Lowe's article where the MDs and PhDs are discussing how coy the manufacturers are about the distribution of mRNA throughout the body following injection, not remaining in the injection site, how the mRNA injections cross the blood brain barrier, and the implications of that for long-term sequelae.
Now do *cough* booster injections again and again *cough*.
mRNA therapies have never been approved for humans. None made to Phase 3 studies.
Also, the Pfizer, Moderna, JnJ, Astra, vacs are so-called sub-unit vaccines. Which is new vacc tech.
For comparison, the new shingles vax (shringrex) is a sub-unit vaccine, it took 12 years to be approved by the FDA.
