Yes natural mRNA typically breaks down super quick. The COVID vax mRNA uses N1-MethylPseudoUridine as a replacement for natural Uridine in the amino acid sequence  to strengthen the mRNA and prevent breakdown. There is also a long PolyA tail at the end of the sequence. The combination of the two make it far more robust than the virus mRNA. 

The Substack blog covers the rest.
