  • As the Omicron variant has rapidly reached nearly every corner of the Earth, Prime Minister Narendra Modi announced that the nasal vaccination and the world's first DNA vaccine against COVID-19 will be available for inoculation soon.

 

About ZyCoV-D vaccine

  • It is the world’s first and India’s indigenously developed DNA based vaccine for COVID-19 to be administered in humans including Children and adults 12 years and above.
  • Developed in partnership with the Department of Biotechnology, under the ‘Mission COVID Suraksha’ and implemented by BIRAC, ZyCoV-D has been supported under COVID-19 Research Consortia through National Biopharma Mission for Preclinical studies.
  • This 3 dose vaccine which when injected produces the spike protein of the SARS-CoV-2 virus and elicits an immune response, which plays a vital role in protection from disease as well as viral clearance.
  • The plug-and-play technology on which the plasmid DNA platform is based can be easily adapted to deal with mutations in the virus, such as those already occurring.

 

What is a DNA-based vaccine, and how does it work?

  • In its most basic form, DNA stores the memories of all biological activities.
  • It also contains hereditary or genetic information about how the body should react in the event of infection.
  • The DNA-based vaccinations operate by transferring a genetically modified blueprint of viral genes into small DNA molecules for injection into persons being vaccinated.
  • The ZyCoV-D was created by inserting a fragment of virus DNA into the human body, which, once inside, causes the virus to manufacture a crucial component that the immune system can recognise and so encounter.

 

Efficacy rate of the DNA vaccine

  • In clinical trials, the vaccination was proven to be 67 per cent effective against symptomatic COVID-19.
  • It demonstrates that DNA vaccinations work and can aid in the control of the pandemic.
  • Vaccines based on DNA are also being developed for a variety of other disorders.
