The world's largest vaccine trial against a new coronavirus infection began in the United States on July 27. This is reported by the Associated Press.
30 thousand volunteers will participate in the testing of the drug. They will help study the vaccine, a prototype of which the American National Institute of health developed with the company Moderna.
The first stage of testing took place in Savannah, Georgia. The third stage is now underway.
During the trial, some volunteers will receive a placebo drug. This will make the test more reliable.
