Interventions
Novel coronavirus broad-spectrum neutralizing antibody SA55 injection (SA55 injection) is developed and produced by Beijing Kexing Zhongwei Biologics Technology Co., Ltd. The main component of SA55 injection is novel coronavirus broad-spectrum neutralizing antibody SA55. Each milliliter contains 150 mg of novel coronavirus broad-spectrum neutralizing antibody SA55. Excipients include histidine hydrochloride, arginine hydrochloride, histidine hydrochloride, sucrose, and polysorbate 80 (II)
