"Efficacy against SARS-Cov-2 has been established. Covaxin has demonstrated an excellent safety record in human clinical trials and in usage under emergency use. Covaxin is now a global innovator vaccine derived from R&D in India," Bharat BioTech Chairman and Managing Director Krishna Ella was quoted as saying by news agency PTI.
Ella also said that the protocols for manufacturing, testing and release of inactivated vaccines meet the requirements of WHO, Indian, and other regulatory authorities.
"These protocols have delivered consistent results over a 15-year period with more than 300 million doses supplied globally, with excellent safety and performance record," the MD said.
The pharma company said final analysis results will be available in June and the final report will then be sent to a peer-reviewed publication.
Covaxin has been jointly prepared by Bharat BioTech and ICMR.
Balram Bhargava, Director General of ICMR and Secretary of Department of Health Research said that Covaxin "works well against" most variants of coronavirus.
