Scientific approach followed in Covaxin approval: Govt rebuts all allegations on Bharat Biotech Covaxin hurried approval

Before Covaxin was approved for restricted emergency use in January 2021, the Subject Expert Committee reviewed the data on the safety and immunogenicity of the vaccine and recommended for grant of permission for restricted use in an emergency situation in the public interest as an abundant precaution, in clinical trial mode, to have more options for vaccinations, especially in case of infection by mutant strains. The SEC's approval for the commencement of phase 3 clinical trial of the proposed dose of Covaxin was based on scientific data presented by M/s Bharat Biotech and established practices in this regard.

Moreover, the purported 'unscientific changes' in clinical trials of Covaxin, as claimed in the news reports, were made after submission made by M/s Bharat Biotech in CDSCO, compliance of due process in CDSCO and with approval from the DCGI. Additionally, later on, based on the further submission made by M/s Bharat Biotech and assessment of interim efficacy and safety data by SEC of CDSCO, the condition of administration of the COVID-19 vaccine in 'clinical trial mode' was removed on 11th March 2021.

Authorization to COVID-19 vaccines including Covaxin for restricted use in an emergency situation with various conditions and restrictions were granted by the national regulator only on the recommendations of the Subject Expert Committee of CDSCO. The Subject Expert Committee consists of domain knowledge experts from the fields of pulmonology, immunology, microbiology, pharmacology, paediatrics, internal medicine, etc.
