mRNA can be used to create practically any protein in the body: antigen against which antibodies can be developed, growth factors, enzymes for rare diseases, host-specific proteins, etc.
The establishment of the ‘mRNA-based platform technology’ could be an important tool for developing variant- proof, safe and effective vaccines. mRNA vaccines do not contain live virus and carry no risk of causing disease in the vaccinated person thus making it suitable for people with compromised immune systems.
mRNA-based vaccines are the ideal choice because of their rapid development and production timeline. mRNA vaccines are considered safe as mRNA is non infectious, non integrating in nature, and is degraded by standard cellular mechanisms. They are highly efficacious because of their inherent capability of being translated into proteins. Additionally, mRNA vaccines are fully synthetic and do not require a host for growth, e.g., eggs or bacteria. Therefore, they can be quickly manufactured in a cost effective manner under cGMP conditions to ensure their “availability” and “accessibility” for mass vaccination on a sustainable basis. These vaccines are safe as mRNA is non-infectious, non- integrating in nature, and degraded by normal cellular mechanisms.

Gennova has developed an mRNA-based vaccine against COVID-19, GEMCOVAC™-19, which overcomes the limitations associated with the currently approved mRNA vaccines.
The currently approved mRNA vaccines have certain inherent limitations like:
GEMCOVAC™-19 is stable at 2 – 8 °C and can be considered superior in terms of deployability in India and other developing nations (especially LMICs) compared to other approved mRNA vaccines. In GEMCOVAC™-19, the mRNA is adsorbed on the surface of the nano-lipid emulsion (as opposed to it being
entrapped in other mRNA vaccines using NLPs), thereby easing manufacturability and minimizing losses.
This also makes the process scalable and amenable for technology transfer – a must for the democratization of the mRNA-based technology globally to eliminate the inequitable vaccine distribution globally.
In addition to the obvious application to infectious diseases, mRNA-based vaccines have the potential for multiple administrations in patients with low intrinsic immunity, thereby opening up bright prospects for developing novel therapeutics. Creating such an unprecedented ‘disease agnostic mRNA-based technology platform’ empowers the world to be ready for future pandemics.
