It uses the spike proteins themselves, in the form of nanoparticles, to trigger an immune response. This will take much less time with mRNA vaccines since once the genomic target is identified, mRNA signature can be quickly and easily edited, and a new version of the vaccine can be manufactured. A first booster dose is recommended 4-6 months after the completion of the primary series. Later data on effectiveness (the vaccine's performance when used in the real world) for adults showed that the protection from the mRNA two-dose primary series wanes over time; but booster doses bring the immune system back to robust levels.
