Prototype/XBB.1.5 Bivalent Vaccine is an investigational vaccine being developed for the prevention of COVID-19. It is currently in Phase 3 clinical development and has not been approved by regulatory authorities. The vaccine is designed to target SARS-CoV-2, the virus that causes COVID-19.
Prototype/XBB.1.5 Bivalent Vaccine is being developed by Novavax, Inc. (NASDAQ: NVAX). The company is conducting clinical trials to evaluate the vaccine's safety and efficacy in preventing COVID-19.
Prototype/XBB.1.5 Bivalent Vaccine is in Phase 3 clinical development. It is an investigational vaccine and has not yet been approved for use. A Phase 3 clinical trial has been completed to evaluate its safety and immunogenicity in adolescents.
Prototype/XBB.1.5 Bivalent Vaccine has been studied in one completed Phase 3 clinical trial, NCT05973006, titled 'Phase 3 Adolescent Study for SARS-CoV-2 rS Variant Vaccines'. The trial enrolled 400 participants in the United States and evaluated the vaccine in healthy volunteers aged 11 years and older.
Prototype/XBB.1.5 Bivalent Vaccine is a recombinant protein vaccine that targets the SARS-CoV-2 virus. It is designed to elicit an immune response against the virus, potentially providing protection against COVID-19. The vaccine is being evaluated for its ability to generate neutralizing antibodies.
