- NEWS SD - Dec 5, 2020 -

Haryana Health Minister Anil Vij, who was administered the trial dose of the indigenous COVID vaccine Covaxin last month, has tested positive for coronavirus, he said in a tweet on Saturday.

According to the details about the trial that have been reported thus far, the participants will receive two intramuscular injections about 28 days apart. Not everyone will receive the vaccine injection. Participants will be randomly assigned to either receive either two 6-microgram injections of Covaxin or two shots of a placebo.

What is a placebo in a vaccine trial?

A placebo is used in clinical trials to test the effectiveness of treatments and is most often used in drug studies. For instance, people in one group get the tested drug, while the others receive a fake drug, or placebo, that they think is the real thing.
