"The mRNA platform is far more modifiable than what Novavax does," he said. With expert resources and tireless advocacy, the AMA is your powerful ally against COVID-19. The biggest difference is the way the vaccine works. Both Pfizers and Modernas vaccines use messenger RNA (mRNA) to deliver a blueprint of sorts to cells in the body. For this reason, mRNA vaccines are easier to adjust than Novavax when a new variant comes along, Kedl said. And, unlike mRNA vaccines, protein-based vaccines do not contain any genetic material, said Dr. Fryhofer.

Download AMA Connect app for KFF COVID-19 vaccine monitor - April 2021. In accordance with the WHO Prioritization Roadmap, Subunit vaccines do not include any live components, containing only the specific parts of a viral or bacterial pathogen. They have a similar safety profile, and a similar efficacy profiles, very high efficacy in all three of these vaccines. Determining the best antigen to include in the vaccine takes time and it will take longer to change this antigen if needed, Yildirim says. In comparison, of the 3,261,656 Moderna doses, 3,077 cases reported adverse reactions, at a 0.09 per cent incidence rate, 191 of which were serious.
