To be clear: mRNA vaccine tech is @20 years old. The only thing “experimental” about it is the efficacy of new vaccines using the technology, not the tech itself.
Right now, it’s being adopted as THE industry standard going forward in large part because of the speed with which new & effective vaccines can be created. Some in the pharma world have declared older methodologies functionally “dead” or “dying”. Another plus is their decreased odds of harmful side effects compared to old tech vaccines using killed or weakened viruses.
It’s also showing promise as a method by which we can produce vaccines for pathogens that have- thus far- eluded scientists’ attempts to create vaccines to. This- plus its speed- can also potentially aid in fighting viruses that mutate rapidly (influenza) or combat diseases that affect so few people that they’re not “economically feasible“ to develop vaccines for- the so called orphan diseases.
