Follow RT on People who already had the coronavirus show rapid immune response to Sputnik V and may require just one shot of the Russian jab during vaccination, a study in Buenos Aires found.
Participants developed Covid-19 antibodies in 100 percent of the cases after both doses of Sputnik V were administered to them, a study by Buenos Aires-based Leloir Institute Foundation (FIL) revealed.
The research, which was supported by the National Scientific and Technical Research Council (CONICET) and the provincial health ministry, saw 142 volunteers from among Buenos Aires medical workers aged between 18 and 59 taking part. They were tested before the vaccination, three weeks after the first shot and the same period after the second one.
