Sputnik V May be India's Third Covid Vaccine by Hannah Joy on March 5, 2021 at 11:09 AM Sputnik V vaccine is one of the world's top three coronavirus vaccines, as the phase III clinical trials of Sputnik V has a strong protective effect across all participant age groups. To cater to the vaccination process of the world's largest democracy, it would be pertinent to bring in safer and more effective vaccines from other countries. However, on February 24, India's drug authority had asked Dr Reddy's, the Indian pharmaceutical company facilitating the trials in the country, to supply data on immunogenicity for going ahead with the approval process. However, experts across the country have been questioning the approval procedure given the fact that the country gave approval to two homegrown vaccines in January this year for emergency use based on modified standards. For instance, Covaxin was granted restricted approval in "clinical trial mode" without any efficacy data.
