NEW DELHI: The Drugs Controller General of India (DCGI) on Tuesday approved Bharat Biotech’s intranasal Covid vaccine, BBV154, for restricted emergency use by people above 18 years of age.
The Hyderabad-based Bharat Biotech claimed its clinical trials among about 4,000 volunteers did not see any side effects or adverse reactions.
“Big Boost to India’s Fight Against Covid-19! Bharat Biotech’s COVID-19 recombinant nasal vaccine approved by DCGI for primary immunization against COVID-19 in 18+ age group for restricted use in emergency situation,” Union Health Minister Mansukh Mandaviya tweeted.
Bharat Biotech said the vaccine has been specifically formulated for intranasal delivery.
“Being an intranasal vaccine, BBV154 may produce local antibodies in the upper respiratory tract. These may provide the potential to reduce infection and transmission. Further studies are being planned,” the company said.
The nasal delivery system would be cost-effective, it added.
Mandaviya said this step will further strengthen "our collective fight" against the pandemic.
India has harnessed its science, research and development (R&D), and human resources in the fight against COVID-19 under Prime Minister Narendra Modi's leadership, he said.
"With the science-driven approach & Sabka Prayas, we will defeat COVID-19," Mandaviya said in another tweet.
iNCOVACC is a recombinant replication-deficient adenovirus vectored vaccine with a pre-fusion stabilised spike protein.
This vaccine candidate was evaluated in phase I, II and III clinical trials with successful results, the press release from the vaccine-maker said.
Clinical trials were conducted to evaluate iNCOVACC as a primary dose schedule, as a heterologous booster dose for subjects who have previously received two doses of the two commonly administered Covid vaccines in India.
Krishna Ella, chairman and managing director of Bharat Biotech, said, "We are proud to announce the approval of iNCOVACC, a global game changer in intranasal vaccines technology and delivery systems.
Despite the lack of demand for COVID-19 vaccines, we continued product development in intra-nasal vaccines to ensure that we are well prepared with platform technologies for future infectious diseases."
Phase III trials of the vaccine were conducted for safety, and immunogenicity in about 3,100 subjects, in 14 trial sites across India, Bharat Biotech said.
BBV154 has been specifically formulated to allow intranasal delivery.
In addition, the nasal delivery system has been designed and developed to be cost-effective in low and middle-income countries.
This trial has been permitted to be conducted at nine sites.
