Bharat Biotech’s Nasal Vaccine Will Work As Booster COVID-19 Dose, Say Reports

New Delhi: India may get the much-talked-about nasal vaccine soon. It will act as a COVID-19 booster dose and protect from infection.

Speaking at the Times Now India@75: The Freedom Summit on Sunday, Dr Krishna Ella, chairman and managing director of Bharat Biotech, said the Hyderabad-based company is working on a combination of Covaxin followed by a nasal vaccine “so that Covaxin primes the system of innate immunity and then the boost by the nasal which produces three immune responses — the IGG, the IGA and then mucosal immunity, all three of which are powerful and can protect a person from getting infected,” Ella was quoted as saying.

The Serum Institute of India (SII) had last week said that a booster dose provides a four-fold increase in neutralising antibody levels.
