The two vaccines, Covishield and covaxin have been approved by DGCI after meticulous research and tests.
Prime Minister Narendra Modi congratulated the Indian companies as well as frontline warriors who have helped the country brave through the ongoing pandemic. “We reiterate our gratitude to doctors, medical staff, scientists, police personnel, sanitation workers and all Corona warriors for the outstanding work done, that too in adverse circumstances. We will remain eternally grateful to them for saving many lives. A decisive turning point to strengthen a spirited fight! DCGI granting approval to vaccines of @SerumInstIndia and @BharatBiotech accelerates the road to a healthier and COVID-free nation. Congratulations India. Congratulations to our hardworking scientists and innovators,” he tweeted.
“It would make every Indian proud that the two vaccines that have been given emergency use approval are made in India! This shows the eagerness of our scientific community to fulfil the dream of an Aatmanirbhar Bharat, at the root of which is care and compassion,” the PM added.
A DGCI statement said on Sunday, “M/s Serum Institute of India, Pune has presented a Recombinant Chimpanzee Adenovirus vector vaccine (Covishield) encoding the SARS-CoV-2 Spike (S) glycoprotein with technology transfer from AstraZeneca/Oxford University. The firm submitted safety, immunogenicity and efficacy data generated on 23,745 participants aged ≥ 18 years or older from overseas clinical studies. The overall vaccine efficacy was found to be 70.42%. Further, M/s Serum was granted permission to conduct Phase-II/III clinical trial on 1600 participants within the country. The firm also submitted the interim safety and immunogenicity data generated from this trial and the data was found comparable with the data from the overseas clinical studies. After detailed deliberations Subject Expert Committee has recommended for the grant of permission for restricted use in emergency situation subject to certain regulatory conditions. The clinical trial ongoing within the country by the firm will continue.”
“M/s Bharat Biotech has developed a Whole Virion Inactivated Corona Virus Vaccine (Covaxin) in collaboration with ICMR and NIV (Pune), from where they received the virus seed strains. This vaccine is developed on Vero cell platform, which has well established track record of safety and efficacy in the country & globally. The firm has generated safety and immunogenicity data in various animal species such as mice, rats, rabbits, Syrian hamster, and also conducted challenge studies on non-human primates (Rhesus macaques) and hamsters. All these data has been shared by the firm with CDSCO. Phase I and Phase II clinical trials were conducted in approx.800 subjects and the results have demonstrated that the vaccine is safe and provides a robust immune response. The Phase III efficacy trial was initiated in India in 25,800 volunteers and till date, ~22,500 participants have been vaccinated across the country and the vaccine has been found to be safe as per the data available till date,” it added.
M/s Serum and M/s Bharat Biotech vaccines have to be administered in two doses. All the three vaccines have to be stored at 2-8° C. After adequate examination, CDSCO has decided to accept the recommendations of the Expert Committee and accordingly, vaccines of M/s Serum and M/s Bharat Biotech are being approved for restricted use in emergency situation and permission is being granted to M/s Cadila Healthcare for conduct of the Phase III clinical trial.
