In April 2021, the
U.S. International Development Finance Corporation (DFC) announced that it would fund the expansion of Biological E's manufacturing capabilities, so that it could produce at least 1 billion doses by the end of 2022.[9]
History
Clinical trials
A phase I clinical trial was carried out to evaluate the safety and immunogenicity of the vaccine candidate in about 360 participants.[4] The phase II concluded in April 2021.[10][11][12]
In April 2021, the
Drugs Controller General of India permitted the vaccine candidate to start phase III clinical trials. A total of 1,268 healthy participants between the age of 18 and 80 years to be selected from 15 sites across India for the trial and intended to be part of a larger global Phase III study.[13][11] On 3 June 2021, India's
Ministry of Health and Family Welfare pre-ordered 300 million doses.[14]
As of December 2021, Biological E announced positive results, but some experts criticized the lack of public data from phase III trials.[15] The developer specifically claimed the vaccine appeared to be over 90% effective against the original variant based on antibody levels.[16] On 28 December 2021, India approved the vaccine for emergency use.[17]
2022
In January 2022, the developers declared that no
G7 countries had funded the project and reiterated their plea for funding for mass production and distribution, arguing that
Moderna had received much more support.[18]
As of August, 70 million doses had been administered to adolescents in India. It was also approved by the Botswana Medicines Regulator Authority.[19] A study reported that the heterologous (Corbevax plus
Zycov-D) vaccine was effective against
Omicron in India.[20]
Financing
Vaccine development was financed with $7 million from mostly private investors, including a $1 million donation by
Tito's Vodka.[21][22] The vaccine technology is given patent-free to manufacturers, although Baylor College receives a fee.[15][23][24]
The BioE company planned to priced the shot at ₹250 (around $3) per dose.[25]
Licensing
The vaccine is not patented and is planned to be openly licensed under
COVAX.[15][26]
