This is India’s first phase 3 efficacy study for a COVID-19 vaccine, and the largest phase III efficacy trial ever conducted in India. The trial has been registered at www.ctrl.nic.in (CTRI/2020/11/028976) and approved by the Drugs Controller General of India.

Trial volunteers will receive two intramuscular injections approximately 28 days apart. Participants will be randomly assigned to receive COVAXIN or placebo.

The trial is double-blinded, such that the investigators, the participants, and the company will not be aware of who is assigned to which group.

COVAXIN has been evaluated in ~ 1000 subjects in Phase I and Phase II clinical trials, with promising safety and immunogencity data. Volunteers who wish to participate in this trial should be adults over 18 years of age.
