If that sounded like red flag, Indian Government had given a specific date - August 15(this year) for the launch of their vaccine from a private company, by which the labs conducting trials for their vaccine should finish all three phases of vaccine trials and give approval[0]. When did the enrollment of participants for the trial start? July 7th(this year).

Why August 15? It is independence day and PM would like to make an announcement that India created the worlds first vaccine.
