Gupta stated that Bharat Biotech’s vaccine was authorized for emergency use. The data from Phase I, Phase II trials, and the ongoing Phase III trials imply that it is secure as well as reliable, and by next month-end tentatively, the results from phase III trials will certainly be offered to verify its efficacy.

He further added that Covaxin is being provided to lakhs of individuals, and there are rarely any major adverse impacts. Importantly, no death has been caused by the vaccine thus far.

Covaxin’s authorization in India has actually drawn objection as the Centre waved a green signal before releasing phase III trial results. Lately, the Health Minister of Chhattisgarh had likewise raised concerns over the vaccine’s efficiency.

The final effectiveness rate of Bharat Biotech’s Covaxin is yet to be determined.

WHO has set a 50% efficiency standard for all the COVID-19 vaccines. Covaxin’s efficiency rate will likely be released in February 2021.

Covaxin is a 2 dosage vaccine, with the 2nd dosage given 28 days after the first dose.

Gupta further added that it is much more reliable to take Covaxin than having irreversible damages to the lungs due to SARS-CoV-2 infection. By next month-end, we will certainly have more real-life data, and there will be much more clearness. It will be a matter of pride if Phase 3 trials offer good outcomes.

Gupta said that the regulator authorizes a drug only if its efficacy is determined to be more than 50%, which has held true for Covaxin, and emphasized that various hypotheses and extrapolation indicate that it will be potential. There should not be any hesitancy in getting vaccinated.
