China Starts Clinical Trials of mRNA Vaccines as Covid Booster Shots

What’s new: Chinese Covid-19 developers will kick off the country’s first clinical trial of using a home-grown mRNA vaccine as a booster shot to protect against Covid-19.

Walvax Biotechnology Co. and partner Suzhou Abogen Biosciences will test the safety and efficacy of their jointly developed mRNA vaccine, known as ARCoV-005, as a reinforcement shot for people fully inoculated with China’s widely used inactivated-virus vaccines, according to a filing published Wednesday by Walvax in the country’s online clinic trial database.
