ICMR, DG, Dr Rajiv Bahl, in the letter, said that the apex research body cannot be associated with this poorly-designed study which purports to present a "safety analysis" of Covaxin.
Calling the reports completely misleading, fallacious, and ill-informed the Health Ministry said, "The government of India and the national regulator Central Drugs Standard Control Organisation (CDSCO) have followed a scientific approach and prescribed norms in approving the Covid-19 vaccines for emergency use authorization."
Ella, Chairman, and MD of Bharat Biotech, which produces Covaxin, met state Minister for Large and Medium Industries Dr. Murugesh R. Nirani, in Hyderabad on Friday, stated the official press release from the ministry of large and medium industries.
The study by 'bioRxiv', an open-access preprint repository for the biological sciences, shared on Tuesday that its study shows that administration of Covaxin booster dose will enhance the vaccine effectiveness against the Delta variant infection and give protection against the Omicron variants BA.1.1 and BA.2.
According to the Union Health Ministry, dedicated centres can be established for the same.
Antibody levels were measured at three-time points: on the day of vaccination (baseline), at month one following the first dose and at month two following the first dose.
An estimated 23%, roughly one in every five persons who are administered the first dose have missed the second jibe for an unexplained reason.
"In a welcome initiative, digital #COVID19 vaccination certificates will now be issued to the clinical trial participants of COVISHIELD & COVAXIN through Co-WIN. The nation thanks them for their incredible commitment & contribution to COVID-19 vaccine research & treatment,"
The study also found that immunization with combination of Covishield and Covaxin was safe and the adverse effects were also found to be similar when compared to the same dose regimen.
A KMC health department official said if supplies keep running out so frequently, it will be difficult to cope with a probable third wave.
