• The US Food and Drug Administration has authorized Novavax's protein-based COVID-19 vaccine for adults, making it the fourth COVID-19 shot available in the United States.
• Novavax's vaccine uses traditional protein-based technology that has been employed for decades against diseases like hepatitis B and influenza, potentially appealing to the 27 million unvaccinated American adults skeptical of mRNA platforms.
• The US government has secured 3.2 million Novavax doses to be released after quality testing, though European uptake has been limited with only about 242,000 doses administered since its December launch.
