According to Baike Biotech, on August 3, Baike Biotech held a national launch ceremony for the liquid nasal spray influenza vaccine in Changchun. The vaccine was upgraded on the basis of the freeze-dried nasal spray influenza vaccine already marketed in China. It was changed from a freeze-dried mixed solvent type to a ready-to-use liquid pre-filled dosage form. There is no need for redissolution or direct use during vaccination. The operation time for a single vaccination was shortened from about 2 minutes to about 8 seconds. It is suitable for children and adolescents aged 3 to 17.
