A phase 4 study comparing Sanofi's protein-based Nuvaxovid vaccine with Moderna's mRNA-based mNEXSPIKE found Nuvaxovid caused significantly fewer and less severe side effects. Conducted with 1,000 US adults, the study showed Nuvaxovid recipients experienced over 50% fewer severe systemic symptoms and 75% fewer severe local reactions. These findings may improve vaccine acceptance and routine COVID-19 vaccination uptake, addressing ongoing health risks despite the pandemic's end. Sanofi plans to expand Nuvaxovid availability in multiple markets from 2026 onward.
