This isn't "mRNA" this is modified-mRNA (where the name Moderna comes from).
Unfortunately they are allowed to abbreviate it as mRNA, which IMO is extremely problematic.
Modified-mRNA uses pseudouridine in some of its base pairs. As such, it is able to remain stable for orders of magnitude more time in many chemical situations.
This practice is incredibly deceptive and lead many in the medical profession to disregard some pretty serious safety issues.
Natural mRNA is too unstable to reliably transport into the cell via injection. Part of the reason mRNA gene treatments spent so long in development without a single approved product.
The two technologies that facilitate this techonology are:
1. Base-modified mRNA (modRNA or :( mRNA), where they substitue uridine.
2. Nano-technology which protects the payload in a bubble of fat, lipid-nano-particles (LNPs).
While LNPs on their own are capable of their own side effects, the modRNA is particularly worrying because of its extended lifetime. IIRC some studies claim to have found it intact many weeks after injection, which would be astounding were we talking of natural mRNA.
Bret Weinstein said of this situation "if a fiberglass tree falls in the forest", which illustrates that most biologists and medical professionals could estimate how long a tree would take to decompose in a forest, however, their estimates would be wildly incorrect if you omitted to tell them the tree was made of fiberglass.
