Sinovac’s candidate – dubbed CoronaVac – induced a positive immune response against COVID-19, according to a statement released by the Chinese biotech company.

The early-stage trials tested the candidate in 743 healthy volunteers between 18 and 59 years of age. That included 143 participants in a phase 1 trial and 600 volunteers in a phase 2 trial.
