"We need two to three weeks' time to study the new variant. We are in discussions to produce a new variant of the Sputnik vaccine if needed.

The duration of the vaccine protection is important which is why we are seeing more cases in Europe," Kirill Dmitriev, CEO of Sputnik maker RDIF, tells NDTV.
