TS Singh Deo expressed concern that the third phase of covaxin clinical trials has not yet been completed. Responding to the Chhattisgarh minister’s letter, Union Health Minister Harshavardhan dismissed the doubts he had raised, said that Bharat Biotech covaxin is completely safe and immunogenic.
Harshavardhan said the Central Drugs Standards and Control Organization (CDCO) had approved the manufacture of covishield and covaxin after examining pre-clinical and clinical trial data on emergencies to deal with the covid-19 situation in the country. In Chhattisgarh, only 9.55 per cent of the total 2,09,512 frontline workers were vaccinated as part of the first phase. It is suggested that measures be taken to improve vaccine coverage so that the vaccine is currently available as needed by the state.
It is well known that the covaxin vaccine has been widely criticized from the beginning. The opposition Congress also already expressed many doubts about covaxin’s effectiveness.
