Clinical trials of the combined use of COVID-19 vaccines – Russian Sputnik V and UK’s AstraZeneca have been started, the statement on the official Twitter page of Sputnik V vaccine said, Trend reports on Feb.20.

According to the statement, the immunity formed after the first shot of AstraZeneca vaccine reduces the efficacy of its second dose (55 percent), so the second shot must be made no earlier than three months after the first one.
