New Delhi: Krishna Ella, CMD of Bharat biotech, issued a statement that phase- 3 of clinical trials for corona vaccine ’Covaxin’ has begun on Monday.

Addressing  participants in an event held by Indian School of Business, Ella said that they have a plan to come up with a nasal spray vaccine which will be released next year. Now the vaccine which is under phase-3 trials has to be injected twice for each person as a dose. So we need nearly 2.6 billion doses which may take vast time and there would be problems  in distribution. The dose of nasal spray is just two drops and can be easily monitored, said Ella.

Trail has begun after Drug controller Of India (DGCI) gave nod for Bharat Biotech which completed Phase 1 &2 with much efficacy ,following proper guidelines and immunology data. For phase-3 trials, Bharat biotech selected nearly 26,000 volunteers across India, which is the largest clinical trial conducted for Covid vaccine in the country.
