A Chinese experimental coronavirus vaccine being developed by the Institute of Medical Biology under the Chinese Academy of Medical Sciences was shown to be safe in an early-stage clinical trial, researchers said.

In a Phase 1 trial of 191 healthy participants aged between 18 and 59, vaccination with the group's experimental shot showed no severe adverse reactions, its researchers said on Tuesday in a paper here posted on medRxiv preprint server ahead of peer review.
