They also already knew which genetic modifications would stabilize the spike in its "prefusion" configuration—important for a robust and safe antibody response—and those that would make the mRNA less inflammatory and therefore safer. They found that there are RNA molecules that help catalyze the synthesis of new RNA, remove some sequences from mRNA, and join peptides to form proteins. Gene-based vaccines take a different tack.
