Covaxin Booster Dose Can Neutralize Both Omicron & Delta Variants Of COVID-19: Bharat Biotech

New Delhi: The booster dose of Covaxin has shown to “neutralize” both Omicron and Delta variants of COVID-19, Bharat Biotech said in a statement on Wednesday.

A booster dose of candidate vaccine generated robust neutralizing antibody responses against both Omicron (B.1.529) and Delta (B.1.617.2) using a live virus neutralization assay, the company said.

It further said that 100% of test serum samples showed neutralization of the Delta variant and more than 90% of serum samples showed neutralization of the Omicron variant.

These data add to the body of evidence that the broad-spectrum mechanism of action of a whole virus inactivated COVID-19 vaccine, like Covaxin, is a viable option in this continuously evolving pandemic, it added.

These were the findings of a study conducted at Emory University demonstrating that sera from subjects who received a booster dose six months after getting a primary two-dose series of Covaxin. More than 90% of all individuals boosted with Covaxin showed neutralizing antibodies. The neutralization activity of Covaxin boosted sera was comparable to what has been observed in mRNA vaccine-boosted sera against the Omicron variant.

It was sponsored by Ocugen, Inc., and Ocugen’s partner, Bharat Biotech, provided the sera of the subjects from the Phase 2 study.
