Valneva Touts Additional Positive Heterologous Booster Data From COVID-19 Vaccine Study

  • Valneva SE VALN reported further heterologous booster data from an exploratory, small clinical study for its inactivated COVID-19 vaccine, VLA2001. 
  • The data show that a booster dose of VLA2001 was well tolerated in previously vaccinated participants with either Pfizer Inc PFE and BioNTech SE BNTX or Moderna Inc MRNA shots.
  • The data confirm the favorable safety profile of VLA2001 seen across all studies, including in homologous or heterologous booster settings.
  • However, in this study, an additional booster dose of VLA2001 elicited only a marginally increased neutralizing antibody response, Valneva added.

  • Valneva is currently seeking regulatory approval for VLA2001 as a homologous and heterologous booster in AstraZeneca - primed individuals who may support the company deploying its inventory in international markets. 
  • Price Action: VALN shares closed at $12.72 on Friday.
