• It is priced at Rs 376.
• It has shown to be 66.6 percent effective.
• Cadila Healthcare, an Indian pharmaceutical business, produced the vaccine.

 

• How it is created:

 

• It has been created using plasmid DNA.
• simple terms, it was created using a portion of DNA from a virus that had been weakened or killed.
• The human immune systems learn to respond to the virus when this DNA fragment is delivered into the body. E Coli cells are used to make the plasmid.

 

• Why is ZyCov – D known as a needle-less vaccine:

 

• Because ZyCov – D is administered by a jet injector.
• An injecting syringe is referred to as a jet injector.
• A tiny stream of high-pressure liquid penetrates the skin's outermost layer here.
• This allows the drug to reach the epidermis' underlying tissues.
• This is preferable to the traditional needle approach.
• This is due to the fact that the vaccines are transported through the cell plasma membrane and nuclear membrane in this technique.
• Conventional approaches, on the other hand, produce low immunogenicity.
