Omicron-specific mRNA vaccine

 

Source: TH

 Context: India’s first indigenous mRNA vaccine for the Omicron variant, GEMCOVAC-OM, has been granted emergency use approval by the Drug Controller General of India.

  • GEMCOVAC-OM has the advantage of being stable at ordinary refrigeration temperatures, and it can be administered using a needle-free Pharma Jet system.
  • Clinical trial data submitted to the regulatory authorities indicated that the vaccine has a strong safety profile and generates more neutralizing antibodies compared to Covishield.
Aspect mRNA Vaccines Traditional Vaccines
Mechanism Tricks the body into producing viral proteins Introduces small or inactivated doses of the whole disease-causing organism or its proteins into the body
Composition Uses messenger RNA (mRNA) Contains small or inactivated doses of the whole disease-causing organism or its proteins
Action mRNA instructs cells to produce viral proteins Provokes the immune system into mounting a response
Protein Production The body produces viral proteins itself Introduction of pre-formed viral proteins
DNA Involvement Utilizes mRNA, which puts DNA instructions into action Does not involve DNA
Immune Response Stimulates an immune response Provokes the immune system to mount a response
Development Process Utilizes mRNA technology Relies on traditional vaccine development methods
Manufacturing Flexibility Can be developed and produced relatively quickly May require longer development and production times
Potential Applications Versatile platform for various vaccines Used for a wide range of vaccines
Storage and Administration May require special storage conditions and specific administration methods Can be stored under ordinary conditions and administered using conventional methods
