COVAXIN™ (BBV152) Booster Shown to Neutralize Both Omicron and Delta Variants of SARS-CoV-2
MALVERN, Pa., Jan. 12, 2022 (GLOBE NEWSWIRE) -- Ocugen, Inc. (NASDAQ: OCGN), a biopharmaceutical company focused on discovering, developing, and commercializing novel therapeutics and vaccines, and its partner, Bharat Biotech, a global leader in vaccine innovation and developer of vaccines for infectious diseases, today announced results from a study conducted at Emory University demonstrating that sera from subjects who received a booster dose of candidate vaccine COVAXIN™ (BBV152) six months after getting a primary two-dose series of COVAXIN™ (BBV152) neutralized the SARS-CoV-2 Omicron and Delta variants. Earlier studies demonstrated the neutralizing potential of COVAXIN™ (BBV152) against SARS-CoV-2 Variants of Concern Alpha, Beta, Delta, Zeta and Kappa.
The study will be published on the pre-print server, medRXiv, in the coming days.
Sera samples from individuals who received a booster of COVAXIN™ (BBV152) were observed to be effective in neutralizing Omicron and Delta variants on a live virus neutralization assay. The neutralization activity of COVAXIN™-boosted sera was comparable to what has been observed in mRNA vaccine-boosted sera against the Omicron variant. More than 90% of all individuals boosted with COVAXIN™ (BBV152) showed neutralizing antibodies. All participants received an initial two-dose schedule of COVAXIN™ (BBV152) at Day 0 and Day 28.
“The global impact of Omicron shows us that the fight against COVID-19 continues, and we’re encouraged that these data demonstrate the value of COVAXIN™ as a primary and booster vaccine,” said Dr. Shankar Musunuri, Chairman, CEO and Co-Founder, Ocugen, Inc. “These results show how a broad-spectrum vaccine has the potential ability to address ever-shifting public health challenges such as new variants and mutations.”
“As the dominant COVID-19 variant throughout the world, Omicron poses a serious public health concern,” said Mehul Suthar, Ph.D., Assistant Professor, Emory Vaccine Center and who led the laboratory analysis. “Data from this preliminary analysis show individuals receiving a booster dose of COVAXIN™ have a significant immune response to both the Omicron and Delta variants. These findings suggest that a booster dose has the potential to reduce disease severity and hospitalizations.”
Dr. Krishna Ella, Chairman and Managing Director of Bharat Biotech said, “We are in a continuous state of innovation and product development for COVAXIN™. The positive neutralization responses against the Omicron and Delta variants, validates our hypothesis of a multi epitope vaccine generating both humoral and cell mediated immune responses. Our goals of developing a global vaccine against COVID-19 have been achieved with the use of COVAXIN™ as a universal vaccine for adults and children.”
COVAXIN™ is formulated uniquely such that the same dosage can be administered to adults and children alike. COVAXIN™ is a ready-to-use, liquid vaccine, stored at 2 - 8°C, with 12 months shelf life and multi-dose vial policy. The same doses of vaccine can also be used for two-dose primary immunization in adults and children and for booster dose vaccinations, making it truly a universal vaccine. COVAXIN™ is not currently authorized or approved for use as a primary or booster dose in the United States.
About the study
This study was sponsored by Ocugen, Inc. and Ocugen’s partner, Bharat Biotech, provided the sera of the subjects from the Phase 2 study.
About COVAXIN™ (BBV152)
With more than 180 million doses having been administered to adults and children outside the U.S., COVAXIN™ (BBV152) is currently authorized under emergency use in more than 20 countries, and emergency use authorization is in process in more than 60 other countries. The World Health Organization (WHO) recently added COVAXIN™ (BBV152) to its list of vaccines authorized for emergency use. And, as many as 110 countries have agreed to mutual recognition of COVID-19 vaccination certificates with India that includes vaccination using COVAXIN™ (BBV152). The trade name, COVAXIN™, has not been evaluated by the FDA.
