Isolation and transport of RNA for medical testing, research, and drug delivery is historically very difficult. Compared to DNA's half life of 531 years, RNA has a half life of just 28 minutes.
COVID-19 has shown that this esoteric laboratory challenge is a huge business opportunity. Early on, we saw constant shortages of viral transport media needed to ship samples for diagnostic testing. More recently, the RNA-based vaccines are often in the news because of the challenges associated with keeping them refrigerated.
