According to the official, the infection took place during the period when the immunity from the disease has not shaped yet.
"The data analysis of clinical tests, the efficiency of the vaccine after the one-time standard dose makes 76 percent during the period from 22 to 90 days. The level of anti-bodies remains on the same level, with a minimal drop. It was only the 13th day after the injection when the symptoms began, so no loss here," Lyashko said.
Earlier, Richard Bergstrom, the local coordinator of the vaccination campaign in Sweden said that the country could get the first batch of Sputnik V vaccine in June. "It's quite possible that those who get vaccinated last are going to get this vaccine. It seems to be quite promising, as the estimated efficiency is on the level of approximately 93 percent", he said.
