A trial of a potential coronavirus vaccine developed in China has indicated that its safe and produces virus-specific antibodies and T cells.

“The challenges in the development of a COVID-19 vaccine are unprecedented, and the ability to trigger these immune responses does not necessarily indicate that the vaccine will protect humans from COVID-19,” said Wei Chen of the Beijing Institute of Biotechnology, who is responsible for the study.
The trial is the first human trial of a potential vaccine to be published in a peer-reviewed journal. Earlier this week, Moderna reported on positive interim data from its human trial, but these results have yet to be peer-reviewed.
The Chinese phase 1 clinical trial was carried out on 108 adults who didnt have coronavirus. The vaccine was well tolerated, with most negative reactions being classified as mild or moderate. Participants either received a low, middle or high dose of the vaccine.
