AIM Vaccine (HKG:6660) said its rabies vaccine received China's National Medical Products Administration (NMPA) approval for holding clinical trials, according to a Friday filing with the Hong Kong bourse.
The human diploid rabies vaccine uses human diploid cells instead of Vero cells, which are homologous to humans and have a natural safety advantage compared with the traditional Vero cell rabies vaccines, the filing added.
The company's shares were down by 17% in recent trading.
