Indian Corona Vaccine 1st phase human trials done |
India`s Bharat Biotech International Ltd and Zydus Cadila Ltd have completed the phase I of clinical trials for their respective vaccine candidates against COVID-19, just three weeks after the two companies started human dosing of the immunization shots against the fatal respiratory disease. Addressing a press conference on Tuesday, Indian Council of Medical Research Director-general Balram Bhargava said, “At present, we have three vaccines in different levels of clinical testing. The first one is the inactivated virus vaccine, which is the Bharat Biotech vaccine, that has completed its phase I study in 11 sites and has started its phase II study. Similarly, for the DNA vaccine of Zydus Cadila, India has completed the phase I study and has embarked on phase II studies; The two drugmakers had received approval from the Drug Controller General of India, V.G. Somani for conducting simultaneous phase I and II trials, which study the vaccine`s safety and immunogenicity, which is the ability to provoke an immune response in the body. The nod allowed the firms to start the second phase without a complete analysis of data of the first phase. Enrolment and human dosing of the vaccine candidates began only in mid-July and the completion of trials in such a short time is unprecedented. The phase I trial is faster than the one developed by the University of Oxford, deemed a frontrunner among COVID-19 vaccines.
