The Russian Direct Investment Fund (RDIF) announced on Thursday that it will "soon offer" a Sputnik V booster shot, specifically made to counter the Delta strain of the coronavirus, to other COVID-19 vaccine manufacturers.
"We've always said that vaccine cocktails are the way of the future. We offer all vaccine makers to use our shot in cocktails against COVID mutations," the fund added on Twitter.
The RDIF previously claimed that the Sputnik V vaccine is more efficient against the Delta variant, initially uncovered in India, than any other COVID shot available at the moment.
