Beijing Wantai Biological Pharmacy Enterprise (603392.SH) announced that its wholly-owned subsidiary Wantai Canghai has received the "Drug Clinical Trial Approval Notice" issued by the National Drug Administration for the recombinant Respiratory Syncytial Virus (RSV) vaccine (CHO cells). It is reported that the recombinant RSV vaccine (CHO cells) was jointly developed by Xiamen University and Wantai Canghai, using gene engineering recombinant technology to produce recombinant protein vaccines using CHOZN cells. The main active ingredient is the self-developed RSV fusion prereceptor membrane fusion protein F. Preclinical data shows that the product is safe and can induce RSV-specific protective immune responses in animals such as mice, rats, guinea pigs, and crab-eating macaques.
