American biotech company Moderna has downgraded the effectiveness of its coronavirus vaccine in the third phase of trials.

DW reports about it with reference to the data of the company.

According to the latest clinical studies, the Moderna vaccine, created using mRNA technology, prevents infection in 90 percent of cases, and severe disease in 95 percent.

It is noted that more than 30 thousand volunteers took part in the third phase of clinical trials.

Note, in December 2020, Moderna estimated the effectiveness of its vaccine at 94.1 percent.
