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. It uses the spike proteins themselves, in the form of nanoparticles, to trigger an immune response. The company is still testing an updated booster for prevention of infection by newer variants. Because information about COVID-19 changes rapidly, we encourage you to visit the websites of the Centers for Disease Control & Prevention (CDC), World Health Organization (WHO), and your state and local government for the latest information.

In accordance with the WHO Prioritization Roadmap, While other vaccines trick the bodys cells into creating parts of the virus that can trigger the immune system, the Novavax vaccine takes a different approach.
