Sinopharm is developing a homegrown messenger RNA inoculation for Covid-19, becoming one of the first big Chinese pharmaceutical groups to pursue the technology to combat the disease.
The state-owned pharma group’s move comes as concerns grow over the efficacy of conventional inactivated virus vaccines, which have dominated the rollout in China. Certain studies have shown the jabs produce fewer antibodies compared with mRNA shots.
Inactivated vaccines, such as Sinopharm’s existing Covid vaccine, use dead viral particles to produce an immune response, while mRNA jabs contain genetic instructions that tell cells to make viral proteins that prime the immune system.
