Pune-based pharmaceutical manufacturer Gennova Biopharmaceuticals Ltd has almost completed the phase 3 trials of its Covid-19 messenger or mRNA vaccine even as the company has started developing an Omicron-specific vaccine using the same technology. Gennova has developed an mRNA vaccine for the Omicron variant, which will be tested for safety and efficacy for use in humans.

Messenger RNA or mRNA technology involves the injection of a small part of the virus’s genetic code (RNA) to stimulate the recipient’s immune response. It contains instructions for human cells to make proteins that mimic part of the novel coronavirus, spurring the immune system into action. No actual virus is contained in the vaccines.
