I didn’t hear the part about MRNA but I am anti-vaccine and that means all of them, other than tetanus and rabies (as needed).

Whenever the President considers that unlawful obstructions, combinations, or assemblages,
or rebellion against the authority of the United States, make it impracticable
to enforce the laws of the United States in any State
by the ordinary course of judicial proceedings,
he may call into Federal service such of the militia of any State,
and use such of the armed forces,as he considers necessary
to enforce those laws or to suppress the rebellion.
Yea I also did not hear the specific term MRNA either. But the conversation did talk about vax designed by AI for indivduals particular health needs.
And that sounds like a “DNA thing”.
Sorry I am not up to par with medical terminology.
The mRNA tech has potential, the implementation into a mandatory, untested over time cellular therapy that has life long (or ending) consequences is criminal.
