Covaxin versus covishield.

The company officially issued a statement on Wednesday against this study. “Recent comparative reports on evaluation of immunogenicity responses on proteins after the protein after the first and second doses of the Indian manufacturing vaccine study have many shortcomings. Journals that state comparative reports say more antibodies are produced by Covishield than Covaxin®. This is not a peer publication The review, also did not succeed statistically and scientifically designed. Design research and behavior reflect ad hoc analysis, rather than the specified hypothesis, “said the company.
