The results of the study were revealed by its partner in the US, Ocugen, which said the study met both co-primary endpoints with robust immune responses.
“Phase II/III observer-blind, immuno-bridging and broadening study was done to generate a broader immune response against the whole virus covering important antigens such as S-protein, RBD, and N-protein,” it said, adding that currently approved vaccines in the US target only S-protein antigen. “Additionally, in contrast to other inactivated vaccines, clinical trials have demonstrated that TLR7/8 agonist adjuvant in Covaxin generates a Th1-biased immune response that induces robust long-term memory B- and T-cell responses,” it said.
