The mRNA can be delivered right into the lungs and has been used to "vaccinate" mice intranasally.

A team from Yale University has developed a new airborne method for delivering mRNA right to your lungs. The method has also been used to vaccinate mice intranasally, "opening the door for human testing in the near future."

While scientists may celebrate this invention as a convenient method to vaccinate large populations, skeptics have started to raise obvious concerns about the potential misuse of an airborne vaccine, including the possibility of covert bioenhancements a concept that has previously been suggested in academic literature.
