The information from these research have been revealed in peer-reviewed journals and accessible for review.

“The overall efficacy of 77.8 % following the phase III clinical trial of Covaxin is wonderful news. Sera from Covaxin recipients have also been evaluated against viral variants detected in India ie the Alpha, Beta, Zeta, Kappa, and Delta. The making of this vaccine entirely on Indian soil is a matter of great pride to every Indian,” stated Priya Abraham, director, National Institute of Virology.

The vaccine has acquired emergency use authorisations in 16 nations together with, Brazil, India, the Philippines, Iran, Mexico.
