Shanghai Fosun Pharmaceutical (Group) Co. said its mRNA vaccine against the coronavirus is still in the initial stage of a phase 1 clinical trial.

The Chinese drug maker shared the progress of its potential vaccine after its Shanghai-listed shares rallied in recent days on reports of its vaccine candidate.

While the National Medical Products Administration has approved the clinical trial of its mRNA Covid-19 vaccine in mainland China, it remains uncertain whether the vaccine will be approved for clinical use, the company said.

In China, vaccines typically require several stages of clinical trials and other certifications before reaching the clinic.
