Russia’s Health Ministry agreed to cut the size of a study of a domestically developed coronavirus vaccine and to stop the enrollment of volunteers. The decision comes a week after developers said enrollment of study volunteers has slowed since Russia began giving out the Sputnik V vaccine while the late-stage study was still continuing. They also cited ethical concerns about giving a dummy shot to some of the volunteers. The study size was cut to about 31,000 from 40,000 participants.
