The Drugs Controller General of India (DCGI) has given vaccine manufacturer Bharat Biotech approval for conducting Phase 3 clinical trials of an intranasal booster dose for those who have received both doses of Covaxin.

  • The chimpanzee adenovirus vectored COVID-19 vaccine (BBV154) will be administered through an intranasal route, and each single dose is 0.5 ml.
  • Experts have noted that an intranasal vaccine as a booster will be easier to administer in mass vaccination drives. 
  • By reducing the need for needles and syringes, among others, such vaccines would also impact the overall cost of a vaccination drive.

Nasal vaccine

  • A nasal vaccine is a vaccine administered to a person via the nose and does not require a needle. 
  • It induces immunity through the inner surface of the nose, a surface that naturally comes in contact with many airborne microbes
