Here is from the first one:
{...
Messenger RNA, or mRNA, was discovered in the early 1960s; research into how mRNA could be delivered into cells was developed in the 1970s. So, why did it take until the global COVID-19 pandemic of 2020 for the first mRNA vaccine to be brought to market?
...}
This is saying mRNA was never used for a vaccine until covid, and clearly the covid mRNA vax totally failed, so this proves mRNA has not ever worked as a vaccine.
The second link showed the history of the development of mRNA from the 1980s, and it was not for vaccines. It was for lipids.
{...
Dr. Pieter Cullis and his team, including Dr. Jeffery Wheeler, turn their attention to using lipid nanoparticles in medicine, in particular for gene therapy drugs that use nucleic acids (like RNA).
The lipid nanoparticles form a protective bubble around the medicine so that it can be delivered to cells safely and effectively.

This was about how the mRNA technology was originally just created by Dr. Robert Malone in order to cure protein deficiencies.
It is absolutely impossible for mRNA to ever work as a vaccine because we do not understand what the immune system identifies, triggers on, or what can be stored in bone marrow T-cell DNA memory.
