Covaxin, India’s first indigenous vaccine for Covid-19, has been found to be 77.8 per cent effective, according to the safety and efficacy analysis data from Phase III clinical trials peer reviewed and published in reputed medical journal The Lancet.

Hyderabad-based Bharat Biotech said the Lancet peer-review confirms the efficacy analysis which demonstrates Covaxin to be effective against Covid-19. The vaccine maker Covaxin is the only Covid-19 vaccine to have demonstrated efficacy data from phase III clinical trials against the Delta variant at 65.2 per cent.

A”The efficacy analysis demonstrates Covaxin to be 77.8 per cent effective against symptomatic Covid-19, through evaluation of 130 confirmed cases, with 24 observed in the vaccine group versus 106 in the placebo group,” the company said.

The efficacy analysis also demonstrates Covaxin to be 93.4 per cent effective against severe symptomatic Covid-19

“Safety analysis demonstrates adverse events reported were similar to placebo, with 12 per cent of subjects experiencing commonly known side effects and less than 0.5 per cent of subjects experiencing serious adverse events,” it said.

The efficacy data also shows 63.6 per cent protection against asymptomatic Covid-19, 65.2 per cent protection against the SARS-CoV-2, B.1.617.2 Delta and 70.8 per cent protection against all variants of SARS-CoV-2 virus.

Covaxin was developed under a partnership with the Indian Council of Medical Research (ICMR) and the National Institute of Virology, with Bharat Biotech receiving the SARS-COV-2 strains through this collaboration.

Bharat Biotech had established an ongoing collaboration with ViroVax since 2019, through the Indo-US Vaccine Action Program, to develop and evaluate IMDG (Alhydroxiquim-II), a novel TLR7/8 agonist molecule, which is formulated as part of the adjuvant in Covaxin. The Adjuvant Program of the US National Institute of Allergy and Infectious Diseases (NIAID) has supported ViroVax since 2009.

The phase 3 trial Efficacy and Safety Study involving 25,800 volunteers across 25 sites in India is India’s largest ever clinical trial conducted for a Covid-19 vaccine.

“I am delighted to see that the phase III efficacy data has also been published in The Lancet, one of the most reputed journals worldwide. This itself speaks high about the strong position of Covaxin amongst other global front-runners Covid-19 vaccines.A The bench to bedside journey of Covaxin in less than 10 months showcases the immense strength of Atmanirbhar Bharat along with the Indian academia and industry in fighting against the odds and carving a niche in the global community,” said Balram Bhargava, Director General of the ICMR.

Recently, the World Health Organization granted emergency use listing to Covaxin enabling countries to expedite their regulatory approval to import and administer doses. It has also received emergency use authorizations in several countries with applications in process in more than 50 countries worldwide. Bharat Biotech has partnered with Ocugen to obtain approvals for Covaxin in the US and Canada.

With more than 150 million doses manufactured, supplied, and with an excellent safety and efficacy profile, Covaxin is a major contributor to the global fight against the Covid-19 pandemic.

The vaccine is currently being evaluated in controlled clinical trials in children 2-18 years of age, with results expected during Q4 2021.

Bharat Biotech said it was poised to achieve its goal of an annualized capacity of Aabout 1 billion doses of Covaxin by the end of 2021.
