> Does that include the engineered quasi-mRNA in the vaccine, that was specially crafted to evade certain types of degradation?

Yes; that's why it has to be stored at such a cold temperature, to stave off that degradation.

The "engineered quasi-mRNA" aspect of things isn't to evade degradation, but initial immune response so it can avoid being broken down before it can express itself. https://www.science.org/content/article/mysterious-2-billion...
