Sanofi's two combination vaccine candidates, NCT06695117 and NCT06695130, received Fast Track designation from the FDA for preventing influenza and COVID-19 in people aged 50+. These candidates combine Sanofi's Fluzone High-Dose or Flublok with Novavax's NVXC19 vaccine. Sanofi and Novavax have a deal for co-marketing NVXC19 from 2025, with Sanofi having sole rights to develop and market the combination with its influenza vaccines. Novavax's NVXC19 shows better tolerability and high efficacy. Sanofi's Vaccines unit has strong sales growth, expecting over €10 billion in annual net sales by 2030.
