The phase I of clinical trials has been completed in less than a month. Indian Council of Medical Research (ICMR) director-general Balram Bhargava said that three vaccines are in different levels of clinical testing. The first one is the inactivated virus vaccine, which is the Bharat Biotech vaccine, and it 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. According to the latest report, Zydus Cadila said phase II of human trials of its COVID-19 vaccine candidate ZyCoV-D will commence from August 6.

The Oxford-AstraZeneca, Moderna, Pfizer-BioNTech, Sinovac, and Sinopharm are at the final stages of Human Trials. However, the World Health Organisation has cautioned Russia against its Coronavirus COVID19 vaccine candidate. Russia has said that it was planning to approve a vaccine candidate developed by Moscow-based Gamaleya Institute in the second week of August. Russia has also claimed that the vaccine will be available in the market in September. The mass vaccination is likely to begin in October. In the second week of July, Russia’s candidate vaccine was likely to have completed Phase I human trials. The phase-II trials commenced on July 13.
