Shanghai's 1st mRNA vaccine approved for trial...

The Center for Drug Evaluation has approved a Shanghai-developed COVID-19 mRNA vaccine for clinical trial, a first for the city.

mRNA (messenger ribonucleic acid) technology is used to deliver genetic material to the body, spurring human cells create a protein from the virus, training the immune system to attack if it encounters SARS-CoV-2, making it more effective than inactivated vaccines.

The Shanghai vaccine, produced by Stemirna Therapeutics, involves a unique mutation of the Omicron and Delta variants, which can offer effective protection against the current dominant variants.

The company previously completed phase-I and phase-II clinical trials of the vaccine in Laos, with none of the participants in the phase-I trial infected with COVID-19, and no serious adverse reactions reported.

Stemirna has built modern vaccine plants in both Pudong and Fengxian districts which, should it be approved for market, will be able to produce some 400 million doses of the vaccine a year.
